摘要
目的:为获得一种方便、准确和灵敏测定游泳池水中尿素的测定方法。方法:应用流动注射技术在线测定游泳池水中的尿素,水样在线蒸馏后可直接进行定量分析。结果:方法的最低检测浓度为2.9μg/L;线性范围0.01~1.00mg/L呈直线,其相关系数r=0.99992;相对标准偏差为0.9%~2.9%;加标回收率为92.0%~108%。结论:本方法操作简便,灵敏度高,线性范围、精密度和准确度均符合检测要求。
Objective: To seek a simple, accurate and sensitive method for determination of urea in swimming pool water. Methods: Urea in swimming pool has been detected by flow injection analysis ( FIA). Results: The detection limit was 2. 9 μg/L and the linear range of standard curve 0. 01 -1. 0 mg/L ( r = 0. 99992). The relative standard deviation and recovery rate were 1.8% - 8. 2% and 88. 2% - 108%, respectively. Conclusion:The method is simple, sensitive, rapid and accurate.
