Abstract

NANOSIZED POLLUTANTS ARE WIDELY PRESENT IN THE AQUEOUS ENVIRONMENT. SINCE THE NANOPARTICLES HAVE MANY USAGES IN VARIOUS FIELDS [1-3], THEREFORE THEY TRANSFERRED OR ENRICHED IN THE WASTEWATER. THESE NANOMATERIALS (NM) ARE KNOWN AS NANOWASTE, BECAUSE THEY ADSORBED HEAVY METALS OR ORGANIC POLLUTANTS AND DISPERSE THOSE ON THE ENVIRONMENT [4]. BECAUSE OF THE EXTREMELY LOW CONCENTRATION OF NMS AND THE COMPLEX MATRIXES IN REAL ENVIRONMENTAL AND BIOLOGICAL SAMPLES, A SEPARATION STEP THAT NOT ONLY CAN PRECONCENTRATE NMS BUT ALSO PRESERVE THE SIZE AND SHAPE OF NMS IS URGENTLY NEEDED. RECENTLY, THE CLOUD POINT EXTRACTION (CPE) WITH A COMMERCIALLY AVAILABLE AND LOW COST SURFACTANT (TRITON X-114) IS GENERALLY APPLICABLE FOR REVERSIBLE CONCENTRATION/SEPARATION OF NMS FROM AQUEOUS DISPERSIONS. SINCE THE COACERVATES CAN EXTRACT ANALYTES WITH NO NEED FOR AN ORGANIC SOLVENT. FURTHERMORE, THE SIZE AND SHAPE OF NMS WERE PRESERVED DURING PHASE TRANSFER AND STORAGE IN A SURFACTANT-RICH PHASE. THUS, TX-114-BASED CPE HAS THE POTENTIAL TO BE, APPLIED IN EXTRACTING ENGINEERED NMS FROM ENVIRONMENTAL WATERS. TODAY BECAUSE OF THE MORE APPLICATION OF NANOMATERIALS AND THEIR POLLUTIONS, THEREFORE, IT IS VERY IMPORTANT THAT WE INTRODUCE THE USEFUL TECHNIQUE FOR THIS PURPOSE. IN THIS ARTICLE WE INVESTIGATED ON THE APPLICATION OF THIS SEPARATION TECHNIQUE FOR SEPARATION OF NMS FROM WASTEWATERS.
