Action of ۴-[(Z)-(۴-Methoxybenzylidene)amino]-۵-methyl-۴H-۱,۲,۴-triazole-۳-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 ۴-[(Z)-(۴-methoxybenzylidene) amino]-۵-methyl-۴H-۱,۲,۴-triazole-۳-thiol (MAMTT) (Schiff base). The maximum absorbance was found to be at ۶۱۳ nm. Experimental conditions were optimized. Beer’s law was seen in ۱۲.۷-۵۰.۸۳ µg/mL of copper concentration range. Calculated molar absorptivity, detection limit and quantification limit of the complex were ۰.۳۰۷x۱۰۴ L mol-۱.cm-۱, ۶.۳۲۸ µg/cm۳ and ۱۹.۱۷۷ µg/cm۳, respectively. The study of interference of common ions was carried out. The current process was enforced for the estimation of copper in water samples.
