摘要
总磷是影响地表水环境质量的一项关键性指标,传统手工监测方法操作繁琐、人为影响因素较大.本实验采用手工法和仪器法分别对不同标准样品和实际水样中的总磷从校准曲线、方法检出限、方法精密度、方法准确度、加标回收率等几个方面来进行比较分析,通过对手工法和仪器法的测定结果进行统计学分析,结果表明仪器法和手工法测得的水样总磷结果并无显著性差异,仪器法能较好地替代传统手工监测方法.
Abstract
Total phosphorus is a key indicator that affects the quality of surface water.Traditional manual monitoring methods are laborious and have significant human interference.In this experiment,the total phosphorus in different standard samples and actual water samples was compared and analyzed from the perspectives of calibration curves,method detection limits,method precision,method accuracy,and spiking recovery rates using both manual methods and instrumental methods.By statistically analyzing the measurement results of the manual method and the instrumental method,the results show that there is no significant difference in the total phosphorus results obtained by the manual method and the instrumental method.The instrumental method can replace the traditional manual monitoring method to a good extent.
