Filter paper is a kind of paper with good filtration performance. The paper is loose and has strong absorption properties to liquid. The filter paper usually used as a filter medium to separate the solution from the solidin analytical laboratory . At present, the filter papers produced in China mainly include quantitative analysis filter paper, qualitative analysis filter paper and chromatographic qualitative analysis filter paper. Both the quantitative filter paper and the qualitative filter paper are both cellulose filter papers and are not suitable for other types of filter paper such as glass microfiber filter paper. 2. Qualitative filter paper is used for qualitative chemical analysis and corresponding filtration separation. Qualitative filter paper is generally used to filter the solution, and it is a qualitative experiment that does not require calculation of chloride, sulfate, etc. Quantitative filter paper is used for precision calculation of numerical values, such as determination of residue, insoluble matter, etc. Usually, after filtering with a quantitative filter paper, it is also necessary to enter a high temperature furnace for processing. Quantitative analysis of filter paper In the manufacturing process, the pulp is treated with hydrochloric
