| Abstract: | A rapid, sensitive, and highly selective test based on the reaction of copper(I) with thio-Michler’s ketone was developed for the detection and semiquantitative determination of 0.001–2 mg/L copper in natural and potable waters using preconcentration in a portable indicator device. Diffuse reflectance spectroscopy was used to select reagent concentrations for immobilization on paper and study the conditions and performance characteristics of the procedure. |
