Pyrrolidine dithiocarbamic ammonium can cause a sensitive incision on the cathodic branch of dE/dt-E oscillogram at -0.80 V(vs.SCE) in 0.1 mol/L KCl solution. When Co. 2+、Ni. 2+、Cd. 2+、Ga. 3+ and In. 3+ are present...Pyrrolidine dithiocarbamic ammonium can cause a sensitive incision on the cathodic branch of dE/dt-E oscillogram at -0.80 V(vs.SCE) in 0.1 mol/L KCl solution. When Co. 2+、Ni. 2+、Cd. 2+、Ga. 3+ and In. 3+ are present in KCl solution containing pyrrolidine dithiocarbamic ammonium the depth of the incision varies. A linear relationship between the incision depth and concentration of the metal ions is established and the second-order differential simple oscillographic voltammetry is applied to quantitative determination for these ions. The cobalt ion in molecular sieve is also determined with satisfactory results.展开更多
