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 0.307x104 L mol-1.cm-1, 6.328 µg/cm3 and 19.177 µg/cm3, respectively. The study of interference of common ions was carried out. The current process was enforced for the estimation of copper in water samples.
