摘要
与液液萃取法相比 ,固相微萃取法测定 5种有机磷农药精密度和灵敏度更高 ,并具有较好的相关系数和较低的检出限 ,且使用时萃取头上的待测物至少保留 2 4h不会损失 ,方法简便 ,快捷 。
Determination five organophosphorus pesticide by solid phase extraction method comparing with liquid-liquid extraction method,the previous one has higher precision and sensitivity,and has a better correlation coefficient and lower detection limit,the extract can retain 24 hours without lost.The method is fast,simple and no pollution.
