| Abstract:

A new trend in extraction and preconcentration of cadmium (II) using azo-azomethinedye6,6'-((1E,1'E)-(1,2-
phenylenebis(azanylylidene))bis(methanylylidene))bis(2-methoxy-3-((6-methoxybenzo[d]thiazol-2-
yl)diazenyl)phenol)(L1)after its synthesis and characterization by UV-visible, FT-IR, 1H-NMR and Mass spectra. Cloudpoint
extraction (CPE) its determination by FASS. The effect of the several factors on the CPE efficiency is optimized
by one-factor-at-a-time (OFAT).Extensive thermodynamic study has been presented to understand the mechanism of
extraction andsolubilisation of ion-association complex in micelles. Under theoptimized conditions, enrichment factor
of 51.259 is achievedleading to limit ofdetection and limit of quantitation of 0.012464and 0.041546µg mL-
1respectively. The linearity of 0.01-1.3µg mL-1,The precision (RSD%;n=8) of the proposed method is of 1.308%at
0.05µgml-1Cd(II). This method is applied in thedetermination of Cd(II) in various environmental samples.
