摘要
本文选用2种水质快速检测产品(DPD检测试剂法和MN检测试纸条)对不同溶液的p H值和不同离子质量分数进行半定量检测。结果表明,DPD试剂对碱性溶液具有更高的精度,而MN试纸能更好地检测酸性溶液和自来水。对于铜离子、铁离子、氯离子、亚硝酸根离子和铅离子,DPD和MN测试试纸或试剂都能够准确和快速地进行有效检测。
In this paper, DPD reagent method and MN test strip are chose as rapid detection methods of water quality for semi-quantitative detection of p H value and various ions in different solution. The results show that the DPD reagent method has higher accuracy for alkaline solution detection, but MN test strip can better detect acidic solution and tap water than alkaline solution. For copper, iron, chloride, nitrite and lead ion, both DPD reagent method and MN test strip are able to detect them accurately, fast and effectively.
