| 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. |
