Abstract
The study of the reaction of the new spectrophotometric reagent with Cu2+, N-allyl-N'-(sodium p-aminobenzenesulfonate)-thiourea(ASAT)'s preparation an d its characteristics are described. It was found that this reagent can rea ct with some ions having characteristic phenomena, and, also determine a mi croamount of copper (epsilon(303 nm) = 2.39 x 10(5) L . mol(-1) . cm(-1)) i n aqueous solution. The method's sensitivity and selectivity are good. The new methods are simple and convenient and can provide satisfactory results on samples.
