Studies in Chelating Behavior Of Eriochrome Cyanine - R With UO (VI) And Y(III) in Presence Of Micelle Forming Surfactants, CTAB and TX.

The Complex reactions of some rare earths in the presence of Cetyltri methyl Ammonium Bromide (CTAB) and Triton X (TX-100) have been studied in detail.

Description
Summary:The Complex reactions of some rare earths in the presence of Cetyltri methyl Ammonium Bromide (CTAB) and Triton X (TX-100) have been studied in detail. Precision and Accuracy data has been determined which has shown increase in both in the presence of surfactants. Dye - Surfactant complex i.e. modified reagent used as a ligand has shown a bathochromic effect which changes to hypso chromic shift in presence of metal ions. The composition of chelates of uranium with Eriochrome Cyanine R was found to be
1: 1 in the absence of the surfactant and
1: 2 in the presence of CTAB and TX. However, the composition of Y, with ECR was found to be
1: 2, both in presence and absence of CTAB and TX. The studies on evaluation of stability constants as well as on various analytical parameters including effect of foreign ions proves the utility of ECR in the spectrophotometric micro determination of metal ions under study.
