A very simple and sensitive method for quantitative measurement of paraquat in plasma, urine and some drinks is described. The paraquat radical formed by its reduction can be detected by electron spin resonance spectroscopy (ESR) at room temperature without clean-up or concentration process of samples. The sensitivity limit is 0.1 microgram paraquat/ml and the required amount of sample is 100 microliter. The time needed for the measurement is within 10 min.
描述了一种用于定量测定血浆、尿液和一些饮料中百草枯的非常简单且灵敏的方法。其还原形成的百草枯自由基可通过电子自旋共振光谱（ESR）在室温下检测，无需对样品进行净化或浓缩处理。检测限为0.1微克百草枯/毫升，所需样品量为100微升。测量所需时间在10分钟内。
