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.
Flotation method is to use the solvent flotation spectrophotometry in the carbon dioxide atmosphere with CTMAB as the collector, and the composition of the ion-association complex (CTMA ~ + I_3 ~ -) The test shows that the method has higher sensitivity, better accuracy and repeatability.
