摘 要:建立了纳滤膜样品中间苯二胺和哌嗪残留量的测试方法,加入色谱甲醇超声提取待测物,经过滤浓缩后,甲醇定容气相进样。出峰时间定性,峰面积定量,建立内标法标准曲线。此方法简单、易操作,重现性好。A method for the determination of m-phenylenediamine and piperazine residues in nanofiltration membrane samples was established.The samples were extracted by chromatography with methanol,after enrichment and concentration,were injected in constant volume gas phase.The Standard Curve of internal standard method was established by qualitative analysis of peak time and quantitative analysis of peak area.The method is simple,easy to operate and has good reproducibility.
