Abstract
A rapid and sensitive spectrophotometric method for the determination of co pper(II) with 4-vanillideneaniino-3-methyl-5-mercapto-1,2,4-triazole (VAMMT ) is described. VAMMT reacts with copper(II) at pH 8.5 to give a green colo red complex which shows an absorption maximum at 430 nm. Sandell's sensitiv ity and molar absorptivity of the complex are 0.0646 mug/cm(2) and 9.929x10 (2) I mol(-1) cm(-1) respectively. The effect of foreign ions and other exp erimental variables are studied. Cu(II) has been successfully determined in various alloy samples.
