A simple, fast, and accurate method has been developed to determine residues of bromacil (5-bromo-3-sec-butyl-t-methyluracil) herbicide. Following sample extraction, filtration, and concentration, the herbicide is determined using a gas chromatograph equipped with a thermionic nitrogen/phosphorus detector. The method has been used to recover 0.04 ppm bromacil added to citrus, pineapple, soil, and water, and 0.1 ppm bromacil added to alfalfa hay.
已开发出一种简单、快速且准确的方法来测定溴莠定（5-溴-3-仲丁基-1-甲基尿嘧啶）除草剂的残留量。样品经提取、过滤和浓缩后，使用配备热离子氮/磷检测器的气相色谱仪测定该除草剂。该方法已用于回收添加到柑橘、菠萝、土壤和水中的0.04 ppm溴莠定，以及添加到苜蓿干草中的0.1 ppm溴莠定。
