采用固相萃取法对水样进行提取富集,液相色谱法测定水中2种邻苯二甲酸酯类和阿特拉津有机污染物,并对方法进行了探索、优化和验证。在固相萃取过程中,研究了水体pH、洗脱液组份对邻苯二甲酸酯和阿特拉津萃取回收率的影响,解决了邻苯二甲酸酯和阿特拉津回收率不高的问题。在空白水加标实验中,邻苯二甲酸酯的回收率为89.3%~92.2%,阿特拉津回收率为88.9%,获得了较高的回收率及测定精度。除此之外,还对地表水进行了加标回收实验,结果符合要求。
採用固相萃取法對水樣進行提取富集,液相色譜法測定水中2種鄰苯二甲痠酯類和阿特拉津有機汙染物,併對方法進行瞭探索、優化和驗證。在固相萃取過程中,研究瞭水體pH、洗脫液組份對鄰苯二甲痠酯和阿特拉津萃取迴收率的影響,解決瞭鄰苯二甲痠酯和阿特拉津迴收率不高的問題。在空白水加標實驗中,鄰苯二甲痠酯的迴收率為89.3%~92.2%,阿特拉津迴收率為88.9%,穫得瞭較高的迴收率及測定精度。除此之外,還對地錶水進行瞭加標迴收實驗,結果符閤要求。
