摘　　要：浮选法是在二氧化碳气氛中,以溴化十六烷三甲基铵(CTMAB)为捕收剂,用溶剂浮选吸光光度法.对离子缔合物(CTMA^+I_3^-)的组成进行测定.试验表明,方法有较高的灵敏度.较好的准确性和重性现.It is reported in this paper that a spectrophotometric determination of iodide as an ion associate of CTMA^+I_3^- after solvent floatation in an atomosphere of carbon dioxide and using cetyl trimethyl ammonium bromide as collector is proposed. The method has high sensitivity and good accuracy and precision.
