action of 4-[(z)-(4-methoxybenzylidene)amino]-5- methyl-4h-1,2,4-triazole-3-thiol as chemosensor for the trace amount of copper in aqueous media

This research study evaluates a novel, sensitive, and selective spectrophotometric method for the estimation of copper(ii) by using a new chromogenic reagent 4- [(z)-(4-methoxybenzylidene) amino]-5-methyl-4h-1,2,4 -triazole-3-thiol (mamtt) (schiff base). the maximum absorbance was found to be at 613 nm. experimental conditions were optimized. beer’s law was seen in 12.7-50.83 μg/ml of copper concentration range. calculated molar absorptivity, detection limit and quantification limit of the complex were 0.307x10^4 l mol^-1.cm^-1, 6.328 μg/cm^3 and 19.177 μg/cm^3, respectively. the study of interference of common ions was carried out. the current process was enforced for the estimation of copper in water samples.
