本文研究了铅和铜在磷酸—硫氰酸钾底液中的极谱行为,提出了同时测定锑制品中铅和铜的极谱法,干扰元素少,分析时间短。
In this paper, the polarographic behavior of lead and copper in the phosphoric acid-potassium thiocyanate bottom solution was studied. The simultaneous determination of lead and copper in the antimony product by polarographic method was proposed with less interfering elements and shorter analysis time.
