Removal of Solfur compound from aqueous solution using non ionic surfactant triton X-100 and arisol dye via cloud point extraction

In this paper,triton x-100 is introduced for colorimetric sensing removal ofsulfure compound using micellemediated cloudpointextraction forthe first time. triton x-100 is an-ionic surfactant phase and show strong surface Plasmon absorption intensity.The extraction of triton x-100 which is the surfactant richphase is suppressed in the presence of Arisol red but upon addition of sulfure compound will be start and the extractionof triton x-100 to the surfactant richphase is increasedagain.This removal in the absence of surfactant rich phase will be stoped but that dye is use only for color solution measurement by uv-vis spectrophotometery. Electrolyteeffect onthecloudpointextractionwasstudied.Underoptimum conditions,thechange in removal was investigated.linearly proportional to theconcentration of sulfure in the range of3– 13 ng pergr with a detectionlimitof0.4ngper gr. Therelativestandarddeviationsfor10replicate measurements of20ngper grrespectively.The method was successfully applied to the determination ofsulfure in different water samples.
