摘要
【目的】对双铂电极法高锰酸盐指数自动监测仪的分析性能进行研究。【方法】探讨了温度对测定结果的影响,进行标准物质和实际水样试验。【结果】双铂电极法高锰酸盐指数自动监测仪精密度、准确度、检出限等都能达到预期要求,线性关系较好,实际水样试验与国标法(GB 11892—1989)没有显著性差异。该监测仪自动化程度高、样品和试剂用量小、检测耗时短,更适用于批量样品的检测。【结论】监测仪可应用于地表水、饮用水、地下水等水体中高锰酸盐指数的自动监测。
[Purposes]This paper aims to analyse the analytical performance of permanganate index on⁃line monitor with double platinum electrode method.[Methods]The influence of temperature on the de⁃termination results was discussed,and theexperiments of reference materials and actual water sam⁃pleswere tested.[Findings]Results indicated that the precision,accuracy,detection limit,etc.can meet the expected requirements with good linear relationship.The actual water sample experiment has no sig⁃nificant difference with the national standard method(GB 11892—1989).The monitor has the advantages of small sample and reagent consumption,short analysis time,high automation and issuitable for batch analysis.[Conclusions]It can be applied to online automatic monitoring of permanganate index in sur⁃face water,drinking water,groundwater,and other water.
