Spectrophotometric Determination of Mercury (II) By Simultaneous Micelle Mediated Extraction Through Ternary Complex Formation in Water Samples
نویسندگان
چکیده
In this study, a micelle mediated extraction procedure for preconcentration of trace quantities of Hg(II) as a prior step to its simultaneous spectrophotometric determination has been developed. The method is based on a ternary ion-association of Hg(II), Xylidyl Blue (XB) and cationic surfactant (CTAB). Major factors affecting the efficiency of the method has been studied. The limit of detection (LOD) under optimum conditions based on 3S b was 4.65 ng mL-1. The proposed method has been applied for determination of trace amount of mercury in water samples with satisfactory results.
