Determination of New Pesticide Phenazine-1-carboxamide Residue in Tomato and Soil by HPLC with DAD
摘要
Abstract
Phenazine-1-carboxamide is a new pesticide.This paper evaluates the residue of phenazine-1-carboxamide in tomato and three kinds of soils.New methods for determining phenazine-1-carboxamide residue in these matrices were developed by high performance liquid chromatography detection.Phenazine-1-carboxamides from soil with ammonia water + ethanol + dichloromethane = 1+2+3 (v/v)and from tomato with acetonitrile were exacted,followed by chromatography columns (basic aluminum)cleanup. The mean recoveries of phenazine-1-carboxamide in soil and tomato were 80.2% to 95.7% and 80.1% to 85.6% respectively,while the relative standard deviations were 2.14% to 4.17% and 4.12% to 5.17%, respectively.The minimum detectable quantity of phenazine-1-carboxamide was 0.2 ng,and the limit ofdetection was 0.01 mg/kg.In a whole,this method is simple and reliable,and has weak matrix effects, which satisfies the requirement of pesticide residue analysis.It is applicable to determine the phenazine-1-carboxamide residues in soil and tomato.关键词
