HPLC法测定种衣剂中多菌灵、福美双含量

Measurement of carbendazim and thiram in maize dressing by HPLC

采用高效液相色谱法(HPLC法)测定种衣剂中多菌灵、福美双含量。实验结果表明,该方法测定的多菌灵、福美双在一定的质量浓度范围内呈良好线性关系,平均回收率分别为98.3%、97.1%,相对标准偏差分别为0.625%、0.995%。该方法简便、准确可行、灵敏度高。

The concentration of carbendazim and thiram in maize seed coating agents was determined by high performance liquid chromatography.The concentration of carbendazim and thiram had favorable linear relationships with their absorbency.The average recovery rates of carbendazim and thiram were 98.3%,97.1% respectively;and the relative standard deviations were 0.625%,0.995% respectively.This method was sensitive and exact.
