Abstract

HALLOYSITE is a kaolinite-type ALUMINOSILICATE (AI2Si2O5(OH)4 nH2O) clay with 1: 1 layer ratio, it has a nano/micro tubular structure and it abundantly is found in nature. Due to various characteristics such as nanoscale lumens, high length-to-diameterratio, relatively low hydroxyl group density on the surface, etc., numerous exciting applications have been discovered for this unique, cheap and abundantly deposited clay. After a brief summarizing of applications in controlled release, nanotemplating and sorption, we emphasize the applications of HNTs in the fabrication of polymer nanocomposites Conducting polymers have recently become the object of numerous investigations because of their greatpotential in device applications, such as transistors sensors, actuators batteries, and so on. Polyaniline (PANI) is one of the most important conducting polymers due to its high conductivity, ease of preparation, good environmental stability and large variety of application such as electrochromic devices, secondary batteries and catalysis and drug delivery.In the current work, anilline was polymerized on the surface of HNTs by chemical polymerization in the various ratios of weight. By this way, HNT/PANI was obtained and the morphology of these nano composites were compared with each other by SEM technology, also the XRD, FT-IR and UV-Vis spectrums of these nano composites were investigated. Finally, HALLOYSITE nano tubes (HNTs) and its conducting nano composites obtained by HNTs were used as nano-adsorbents for removal of the cationic dye of Malachite Green (MG). The adsorption of the dye was studied with batch experiments. The effect of adsorption time, pH and amount of adsorbent on sorption capacity were studied. Adsorption isotherms such as Feundlich, Langmuir and Temkin were studied on prepared nano composites. Langmuir isotherm exhibited the best fit with the experimental data for most of adsorbents. Also, sorption kinetics was determined by pseudo-second-order and interparticle diffusion models. The adsorption of MG onto adsorbents followed pseudo-second-order and interparticle diffusion kinetics.
