本文采用反相离子对色谱及双通道检测分析克·杀单颗粒剂。以LichrospherRp-8不锈钢柱为色谱柱 ,0.01mol/L四丁基溴化铵 (pH=3.2) +乙腈=70+30为流动相 ,双通道检测 :杀虫单检测波长为245nm,克百威检测波长为280nm。该方法的标准偏差分别为杀虫单0.015、克百威0.0066;变异系数分别为0.79%、1.21% ;线性相关系数分别为0.9999、0.9999,平均回收率分别为99.04%、98.83%。 In this paper, reversed-phase ion chromatography and dual-channel detection of grams kill single granules. Using Lichrospher Rp-8 stainless steel column as the chromatographic column, 0.01mol / L tetrabutylammonium bromide (pH = 3.2) + acetonitrile = 70 + 30 as the mobile phase, dual channel detection: insecticidal single detection wavelength of 245nm, The detection wavelength is 280nm. The standard deviation of the method was 0.015 for insecticide alone and 0.0066 for carbofuran respectively. The coefficients of variation were 0.79% and 1.21% respectively. The linear correlation coefficients were 0.9999 and 0.999. The average recoveries were 99.04% and 98.83% respectively.
