Comparative study of two rapid detection methods for water quality

The purpose of water quality testing is mainly to investigate the environmental quality, to study whether the water quality is suitable or suitable for use, to investigate the pollution or the degree of pollution of the water, and to check the efficiency of the water treatment process, etc. 

"Comparative Study of Two Rapid Testing Methods for Water Quality" introduces that the author chooses the water quality analysis test paper and reagent (DPD for short) of Hangzhou Luheng Biotechnology Co., Ltd. to compare with the test paper (MN for short) produced in Germany, and tests the two products. Performance testing and analysis.

in conclusion

In this paper, scientific methods are used to compare two kinds of rapid water quality testing products, MN and DPD, to provide more scientific and accurate support for specialized water quality testing units and ordinary users when using and selecting.

1. In the pH value detection, the detection performance of the MN and DPD test strips is relatively consistent, but the DPD test paper can detect the alkaline solution better, and the MN has better accuracy for the pH value detection of the acidic solution and tap water. ;

2. In the detection of copper ions, iron ions, and chloride ions, MN has a large detection range, but low sensitivity, while DPD has high detection sensitivity and small range; 

3. In the detection of nitrite ions, the detection sensitivity of MN and DPD products is the same, but the accuracy of MN is higher in the high concentration range, and the accuracy of DPD is higher in the low concentration range; In detection, MN can only detect high-concentration solutions, while DPD can only detect low-concentration solutions.
