Investigation of Adsorptivt-Complex Waves of Nickel and Cobalt with Zincon --Consecutive Determination of Trace Nickel and Cobalt in Copper Ore Concentrate

Abstract

Abstract: In the solution of 4 × 10^-5mol/L Zincon-o.4mol/LNH₄Cl-0.6% Na₂SO₃two sensitive adsorptive-complex waves of Ni-Zincon and Co-Zincon were observed by single-sweep polarography. The peak potentials of the waves are -0.84V and -0.96V (vs. SCE), respectively. Various conditions of adsorptive-complex waves of Ni and Co in this system were studied; and the properties of these waves were investigated. The compositions of the complex of Ni and Co with Zincon also were determined to be 1:1.

Key words: Nickel, Cobalt, Zincon, Copper ore concentrate, Oscillographic polaro-graphy
