摘要
20%溴硝醇可湿性粉剂在水稻上已获得正式登记,用以防治水稻恶苗病。本文采用高效液相色谱法,以甲醇:0.04%磷酸水溶液(20:80)为流动相,使用SinoChrom ODS-BP-C_(18)、5μm为填料的不锈钢柱和二极管阵列检测器,在215nm波长下对溴硝醇可湿性粉剂进行分离和定量分析。结果表明,该分析方法在0.224 8~1.124mg/mL线性范围内,相关系数为0.998 8,标准偏差为0.11,变异系数为0.55%,平均回收率为99.8%。
Bronopol 20% WP has obtained full registration on rice to control bakanae disease in China. A method for the separation and quantitative analysis of bronopol by HPLC with methanol and O. 04% phosphoric acidaeetonitrile （20：80 v/v） as mobile phase, SinoChrom ODS- BP - Clscolumn and DAD at 215 nm wavelength was described. The results showed that the method is valid over a range of 0. 224 8 - 1. 124mg/mL the standard deviation of 0, 11 and the variation this range was 99.8%. with the correlation coefficients of above O. 998 8, coefficient of 0. 55%. The average recovery over
