除草地膜中乙草胺的气相色谱分析

GC Analysis of Acetochlor Incorporated within Plastic Film

报道了除草地膜中乙草胺的气相色谱分析方法。以甲苯加热回流除草地膜提取其中的乙草胺，内标物邻苯二甲酸二正戊酯，乙草胺的变异系数为１－０９％ ，回收率为９６－３３％ ，线性相关系数为０－９９９８。

A method of GC analysis of acetochlor incorporated within plastic film — a herbicide controlled release formulation,was introduced in this paper.Acetochlor was extracted by methylbenzene reflux heating and analyzed by GC using dipentyl (o-)phthalate as interna1 standard.The variation coefficient was 1 09% and linear relative coefficient was 0.9998.The recovery was 96.33%.
