A flow injection system with chemiluminescence detection for the determination of asulam, enhancer of the system luminol-H(2)O(2)-horseradish peroxidase, is proposed. The method shows a moderate selectivity against other pesticides usually present in formulations of herbicides and in water. The procedure was applied to the determination of asulam in tap water samples and a recovery study was carried out in order to validate the method. The obtained results show acceptable recovery values (between 88.3 and 93.9%). The detection limit for asulam was 0.12 ng/mL. The precision of the method expressed as relative standard deviation was 1.55% (n = 8), at the 19 ng/mL level.
一种基于流动注射技术并结合化学发光检测的分析方法被用于测定除草定，该方法中化学发光体系的增强剂为鲁米诺-H2O2-辣根过氧化物酶。该方法对通常存在于除草剂制剂和水样中的其他农药具有中等选择性。该方法已成功应用于自来水中除草定的测定，并进行了回收研究以验证该方法的准确性。所得结果表明，回收率在 88.3%至 93.9%之间，具有良好的准确性。该方法的检测限为 0.12ng/mL，在 19ng/mL 水平下的精密度（相对标准偏差）为 1.55%（n=8）。
