【Abstract】 In this paper,a new technique of determination of trace metallic ions in liquid by method of forming ternary complexes is presented,and a flame atomic absorption spectrophotometer is used. The determinations of Fe 3+ ,Co 2+ ,and Cu 2+ were performed after separation and adsorption of their ternary complexes with nitroso-R salt and CTMAB onto benzophenone at 30℃.更多还原
