- 中文摘要: The study of the reaction of the new spectrophotometric reagent with Cu2+, N-allyl-Ne-(sodium p-aminobenzenesulfonate)-thiourea(ASAT)’s preparation and its characteristics are described. It was found that this reagent can react with some ions having characteristic phenomena, and, also determine a microamount of copper (e303 nm = 2.39 o 105 Lamol-1Acm-1) in aqueous solution. The method’s sensitivity and selectivity are good. The new methods are simple and convenient and can provide satisfactory results on samples.
