摘    要:利用Shim-Pack阳离子色谱柱分离了Fe2+, Mn2+, Zn 2+, Ca2+, Mg2+和Cd2+等金属阳离子, 优化了色谱分析条件, 建立了离子色谱(IC)分离、 测定二价锰离子的方法, 结果表明, 测试的相对标准偏差小于5%, 试样加标回收率为98.78%±9.64%, 对Mn2+的检出限为0.69 μmol/L. 此法可用于自然水体生物膜样品中Mn2+的分析.

关 键 词:离子色谱  生物膜  锰(Ⅱ)  形态分析

Abstract:A determination method for (Mn~(2+)) in natural surface coatings by single-column ion chromatography with a conductivity detector is described. The retention behavior and resolution of a series of cations including (Fe~(2+)), (Mn~(2+)), (Zn~(2+)), (Ca~(2+)), (Mg~(2+)) and (Cd~(2+)) were studied in different concentrations of eluent, flow rate and pH value, and the optimum analytical condition was established. The method was applied to the analysis of surface coatings with satisfactory results, which will contribute to the speciation analysis of manganese oxides in the natural surface coatings.
Keywords:ion chromatography  surface coatings  manganese (Ⅱ)  speciation analysis
