摘要：
A spectrophotometric method for the determination of antimony is described, which is based on a chemical enhancement procedure comprising formation of an equivalent amount of ICl2- in several steps and measurement of the latter by means of Rhodamine 6G. Analyses of water samples gave recoveries of 98-99% of added antimony.
