摘要
本文采用共沉淀定量分离方法对五氧化二钒中所含微量镁进行极谱测定。检出限为1．5mg/L，线性范围为0～0．4mg／L。精确度为：标准偏差S=0．14，变异系数CV=1．92％；相对误差为2．3％．
In this paper, magnesium in vanadium oxide was determined by the method of po-larographic analysis, and was quantitatively sepavated by the method of co-precipita-tion, The said analysis method has a detection limit of 1.5ug/ml (Mg2+) and a linearrange of 0- 0. 4ug /ml (Mg2+).
