Simultaneous determination of HEDP, ATMP and EDTMPS by ion chromatography(离子色谱法同时测定3种有机膦酸类阻垢缓蚀剂)
建立了同时测定有机膦酸类阻垢缓蚀剂羟基亚乙基叉二膦酸(HEDP)、氨基三甲叉膦酸(ATMP)和乙二胺四亚甲基膦酸钠(EDTMPS)的离子色谱检测方法.该方法以Shodex IC NI-424为阴离子交换柱,4 mmol • L-1 H2SO4为流动相,流速为1.0 mL • min-1,非抑制电导进行检测,方法的线性范围为5~200 mg • L-1 ,HEDP、ATMP和EDTMPS的平均加标回收率分别为101.15%、95.48%和92.41%,检出限分别为0.80、4.30和4.27 mg • L-1;对50 mg • L-1标准溶液分别进行8次平行测定,相对标准偏差(RSD%)分别为0...
