摘　　要：硫氰酸钾和α—糠偶酰二肟比色铼已有应用,但将此种试剂用于极谱测定铼则未见报导,为解决不经繁琐分离测定辉钼矿中少量铼,本文试验了在含有还原剂氯化亚锡的酸性介质中,铼与硫氰酸盐和α—联糠酰二肟络合物在滴汞电极上的反应,观察到于电位-0.9伏附近。The rhenium complex with thiocyanate+α-furildioxime in acid media containing stannous chloride gives a sensitive and welldefined peak at about-0.90v(vs.SCE)at the dropping mercury electrode.The detection limit is 0.08μg/ml.Moderate amounts of Mo,W and Mn do not interfere.This method has been successfully applied in the determination of small amounts of rhenium in molybdenum disulfide.
