金属及矿石、冶金中间产品、环境监测中微量锑的测定,目前多采用溶剂萃取法,如孔雀绿光度法,氢化物分离,5-Br-PADAP光度法。资料介绍用巯基棉分离富集多种元素。我们在资料报导苯芴酮光度法测定锑的基础上,研究了分离条件、显色条件,提出了生成多元络合物在水相中直接光度法测定微量锑的操作方法。本法富集倍数大,减少环境污染,结果满意。
Metals and minerals, metallurgical intermediates, environmental monitoring trace antimony determination, the current use of solvent extraction, such as malachite green, hydride separation, 5-Br-PADAP spectrophotometry. Information introduction Sulfhydryl cotton enrichment of a variety of elements. Based on the data of the phenylfluorone spectrophotometry for the determination of antimony, we studied the separation conditions and the conditions for the color development. The method for the determination of trace antimony by direct spectrophotometry in the aqueous phase was proposed. The law enriched multiple, reduce environmental pollution, the results are satisfactory.
