Background and Objectives: Industrial wastewater and water contaminated chemicals are released into the environment and, as a result, contamination of the soil is adsorbed and contaminated with limited resources, cause production of harmful and unhealthy products for health. One of the best ways to remove organic pollutants from contaminated water is by adsorption. The purpose of this study is to remove phenol pigment from aqueous solutions by magnetic NANOPARTICLEs. Materials and Methods: MAGNETITE NANOPARTICLEs were synthesized by the sedimentation method and simultaneously reconstructed Fe+3 / Fe+2 ions with a ratio of 2 to 1 with NaOH in aqueous solution under nitrogen atmosphere and identified by IR, SEM and XRD methods. To determine the maximum phenol red absorption wavelength concentration, the UV-VIS spectrophotometer was evaluated in the wavelength range of 400 to 800 nm, with a maximum phenol-red wavelength of 431 nm. The phenol red adsorption on Fe3O4 NANOPARTICLEs was evaluated in a discontinuous medium. The parameters studied in this study included the initial values of NANOPARTICLEs (0. 005, 0. 01, 0. 015 and 0. 02 g), phenol red primary concentrations (5, 10, 20 and 30 mg/l), primary pH (1, 4, 7, 9 and 12), contact time (5 to 40 minutes) and nano-adsorbent desorption process. Langmuir two-parameter adsorption isotherm models, Freundlich and Tempkin were studied. Experimental comparisons were studied with pseudo-first kinetic models, pseudo-second-order and inter-particle influences. The effect of temperature on the adsorption process was investigated by investigating the thermodynamic constants of the adsorption process including Gibbs free energy (Δ G0), change in entropy (Δ S0) and enthalpy change (Δ H0) at temperatures of 293, 300, 305 and 310 K. Results: By increasing and decreasing pH from 7, the phenol red removal rate was increased. Increasing the phenol red adsorption in low and high pHs relative to neutral pH is due to the conversion of pollutant to ion, which increases the adsorption of phenol red contamination on nano-adsorbent. The adsorption takes after 30 minutes to equilibrium. The maximum adsorption capacity occurs at 30 mg/L of the contaminant in the presence of 0. 01 mg/l of the adsorbent and at 20 ° C and at pH= 7. Due to the process heat-up, the increase in temperature increases the amount of adsorption. It is observed that when temperature increases the amount of adsorption will increase. The Freundlich isotherm is in better agreement with experimental data. The pseudo-second-order model with a correlation coefficient of 0. 9999 and a speed constant of 0. 0202 is the best kinetic model describing the adsorption process. The values of the thermodynamic constants Δ H0 and Δ S0 are 278. 89 kJ / mol and 288. 38 j / k. mol, respectively that indicate that the adsorption process is endothermic and an increase in ambient temperature at the solid-liquid interface during absorption. The negative Δ G0 indicates that the adsorption process is spontaneous. Conclusion: MAGNETITE nano-adsorbent can be used as an appropriate adsorbent to remove phenolic contaminants from polluted aqueous solutions and industrial wastewater before releasing into the environment.

In the past few decades, MAGNETITE (Fe3O4) NANOPARTICLEs have attracted growing research interest as these materials have many applications in medicine and drug delivery. Coated magnetic particles, called carriers are very useful for delivering chemotherapeutic drugs. We are herein reporting a synthesis of doxorubicin-loaded bilayer-surface MAGNETITE NANOPARTICLEs. The particles were first stabilized with Stearic acid as a primary surfactant, followed by Maleic anhydride-methyl acrylate (MAN-MA) copolymer as a secondary surfactant to form NANOPARTICLEs with hydrophobic inner shell and hydrophilic corona. The Doxorubicin (DOX) drug was then loaded to modified magnetic NANOPARTICLEs. The structural, morphological and magnetic properties of as-prepared sample were characterization by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra and scanning electron microscopy/energy dispersive X-ray analysis (SEM-EDAX). The magnetic measurements were investigated, using vibrating sample magnetometer (VSM).The particles were exhibited superparamagnetic behavior at room temperature with saturation magnetization (Ms) about 50 emu/g MAGNETITE. We demonstrate that the drug DOX is attached to the NANOPARTICLEs surface and the binding of DOX to the NANOPARTICLEs was confirmed by FT-IR analysis. The present finding show that DOX loaded NANOPARTICLEs coated by copolymer are promising for magnetically targeted drug delivery.

Nowadays, Azolla become a problem in aquatic habitats. Also, the existence of colors in the water and the effluent of industries cause water contamination. In this research, the application of surface modified Azolla with NANOPARTICLEs of MAGNETITE (Fe3O4) as a natural sorbent has been studied in removal of brilliant blue dye. The size and structure of the NANOPARTICLEs were examined by SEM and FT-IR, and particle size was less than 40 nm. Dye removal parameters including solution pH, ionic strength, absorbent weight, stirring time and solution volume have been optimized. The kinetic of brilliant blue adsorption on surface modified Azolla by magnetic NANOPARTICLEs showed that it is followed pseudo-second-order kinetic which indicate the chemical absorption of the dye on MAGNETITE NANOPARTICLE. Based on adsorption isotherms the process is coherent with Freundlich model. By using Azolla powder surface modified with MAGNETITE NANOPARTICLEs, color removal is done in a very short time with high efficiency, which has the advantage of the application of these particles in treatment of wastewaters containing colored compounds.

Current research had successfully encapsulated magnetic NANOPARTICLEs (MNP) with selective estrogen receptor drug tamoxifen citrate (TAM) using Poly (d, llactice-co-glycolide acid) (PLGA 75: 25) via oil in water emulsion technique. TAM is a good example of a drug that is difficult to dissolve. TAM is currently approved for the treatment of hormone-sensitive and early-stage breast cancer as an adjuvant endocrine therapy. The majority of the prescription medicine in today market is made up of poorly soluble, bioavailable, and quickly metabolized and eliminated drug which is a continuously challenges up to these days. Therefore, it is imperative to overcome this disadvantage by encapsulating TAM inside PLGA together with MNP for improved drug delivery. The MNP coated with oleic acid (OA) was synthesized using co-precipitation method and it is known as OAMNP. The fabricated nanohybrid is known as TAM-PLGA-OAMNP where the TAM was encapsulated together with OAMNP within PLGA. XRD results showed that OAMNP is Fe3O4. FTIR spectra revealed that the TAM was successfully encased into the PLGA structure. TAM-PLGA-OAMNP average size is about 131 ±,28 nm as shown in TEM results. The nanohybrid NANOPARTICLEs showed the absence of hysteresis loop indicative of superparamagnetic properties.

More than 22% of the world's agricultural land is saline, and this trend continues to increase with climate changes. Salinity stress causes leaf color change, osmotic stress, ionic toxicity, prevents growth, photosynthesis and plant performance. Due to their size less than micron, metal NANOPARTICLEs have a great absorption and transmission power in plants. Salinity stress is a major problem in hot and dry areas under tomato cultivation. For this purpose, investigating the mutual effects of the size and type of zinc oxide and iron oxide NANOPARTICLEs on the improvement and change of growth and increasing the resistance to salt stress in tomato plants of the early urbana variety were carried out in the form of a completely randomized and factorial design with 4 replications, at a significant level of 5%. In this research, zinc oxide NANOPARTICLEs in 25 and 50 nm sizes, iron oxide in 25 nm sizes and sodium chloride in 0 and 75 mM levels were used. NANOPARTICLEs and salinity treatments were both applied to the plants. The results showed that salt stress led to a decrease in plant growth parameters such as shoot and root length, leaf area, RWC, ion leakage. Also, NaCl led to an increase in the accumulation of prolin and other aldehydes, sodium, iron and zinc. The application of NANOPARTICLEs had a slight effect in stress-free conditions, but in stressed conditions, these two NANOPARTICLEs alone and especially in combination neutralized the effect of salinity and reduced the damage caused by salinity stress.
