摘要
本文研究了在(NH_4)_2SO_4-CuSO_4-HClO_4-酒石酸钠介质中硒的极谱行为.发现在-0.64~-0.72V硒有敏锐的极谱波.硒含量在1.27×10^(-7)~2.53×10^(-5)mol/L范围内峰电流与硒浓度成正比.可不经分离直接测定电解锰中微量硒.
Polarographic behaviour of selenium was studied in (NH4)2SO4-CuSO4-HC1O4-H5C4O6Na solution and peak height for polarographic wave of selenium was found in-0.64to-0.72V.Change of peak height with the concentration of selenium are linear in the range from 1.27×10-7to 2.S3×10-5 mol/L. The selenium in electrolytic manganese was direct determinated without prior separation.
