| Abstract: | Adsorption of I-phenyl-3-(2-thiazolyl) thiourea-copper( II) complex on polyurethane foam has been studied and a new method is described for the photometric determination of copper(II). The complex can be extracted into chloroform and it has λmax at465 nm. The absorbance shows a linear relationship over the concentration range 10-100 mg Cu(II) in 10 ml chloroform. The molar absorptivity and sensitivity are found to be 1.37 x 104 1 mol-1 cm-1 and 0.014 mg cm-2 of Cu(II) for 0.001 absorbance respectively. The .method has been successfully applied for the estimation of micro amounts of copper(II) in alloys. |
