Investigation on the Electrochemical Behavior of cobalt-Nitroso R Salt and Its Analytical Application Ⅱ . The Electrode Reaction Process of Nitroso R Salt and Its Complex with Cobalt

亚硝基R盐(NRS)在0.1mol/LKCl溶液中,其电极反应过程为准可逆双电子过程,在有氯化十四烷基吡啶(TPC)存在时,钴与NRS和TPC形成三元钴络物,Co(Ⅲ):NRS:TPC=1:3:6,稳定常数1gβ为:37.80,探讨了其电极反应机理。

Cobalt and nitroso R salt in the solution of 0.1 mol/L KC1 in the presence of tetradecyl pyridinium chloride can form ternary complex.The molar ratio of Co( Ⅲ ) : (NRS) : (TPC) was 1:3:6 and the apparent stability con-stant(β)was calculated to be 6.5 f44 1037.The current character, the reversibility of the electrode process and the mechanism of electrode reaction of nitroso R salt and its ternary complex were investigated.
