摘要
结合固相萃取预处理技术原理和普遍操作流程,提出改进固相萃取预处理操作过程的方案,并以水中有机磷农药加标回收率为表征,进行对比实验分析。结果表明,操作过程优化对提高整个实验的准确性起非常关键的作用,而操作过程简化在保证实验效果的前提下提高实验效率,因此该改进方案可行。
Based on technology principle and common operation process of solid phase extraction （SPE）, the paper put forward improvement schemes of the operation process, Contrast experiments were carried out by taking the recovery of organophosphorus pesticides in water as the index. Results showed that process optimization played a key role in experimental accuracy and process simplification improved experimental efficiency on the premise of experimental effect, So the improvement schemes were feasible.
