摘要
脱脂棉分离一词，是我们首次提出的。应用于铜的二乙基二硫代氨基甲酸钠萃取光度法测定，收到了：简化操作，节省萃取剂用量，实现一次萃取方法，提高测定灵敏度，增进精密度，减轻环境污染等效果。并认为，如能在其他一些萃取光度中得到应用，也可收到相似效果。
Fat-free cotton copper separation was the term firstly proposed by us in this paper. it was successfully applied in sodium diethydithiocarbamate extraction spectrophotometric determination of copper with advantages such as:simple to dewater process, less consumption of extraction -solvent realization of solvent extraction only once, not fwice ormore improvement both in accuracy and reliability, less enviromental pollution, ect, It was considered to be applicable to certain other extraction spectrophotometric determinations with similar advantages.
