摘要: 本文研究了镓的吸附催化波的示波极谱性能,并对催化波的性质,影响因素,干扰及分离方法等进行了试验。确定了最适宜的分析条件。同时,测定了两种矿样中的镓并与罗丹明B比色法对照,结果满意。

Abstract: In this paper, the oscillopolarographic behaviour of the adsorptive catalytic wave of Gallium has been studied. It is found that Ga can be determined from the height of a catalytic wave at -0.92 (vs. SCE) in the formic acid and ammonium formate buffer solution with cupferron. The optimum conditions are 0.15M HCOOH, 0.05M HCOONH4, 8.0×l0-5M cupferron and pH = 2.6-3.0. The calibration graph covers the range 7.2×10-8M-3.6×10-8M-Ga. The nature of the catalytic wave was considered to be the adsorptive complex wave of Ga with cupferron.
