Application of a rapid scanning photodiode-array spectrophotometer to the continuous determination of nickel and cobalt

A computer-processed linear photodiode-array spectrophotometer is used for the continuous and simultaneous determination of nickel and cobalt in the process water of a storage battery. Disodium ethyl-bis(5-tetrazolylazo) acetate is used as the pnotometric reagent. The interference of copper(II) is e...

Description
Summary:A computer-processed linear photodiode-array spectrophotometer is used for the continuous and simultaneous determination of nickel and cobalt in the process water of a storage battery. Disodium ethyl-bis(5-tetrazolylazo) acetate is used as the pnotometric reagent. The interference of copper(II) is eliminated by reduction and complexation of copper(I).
