摘要
本工作研究了在NH_4Cl溶液(pH=4.50～7.00)中N-苯甲酰苯胲(BPHA)-稀土络合物的极谱行为以及电极反应机理;提出了测定钆的一种新方法,用此方法可检测1.0×10^(-6)～1.2×10^(-5)mol·L^(-1)的钆。
The polarographic behaviour of BPHA and its rare earth complexes is studied. Except euro-pium, the adsorptive complex waves of other rare earth elements have been observed in 0.4mol/LNH_4Cl (pH 4.5～7.0). The linear rang of determination Gd (Ⅲ) is 2.0×10^(-6)～1.2×10^(-5)mol/L. The detection limit is 1. 0×10^(-6) mol/L.
