How To Choose Filter Paper
In general, filter paper can be divided into two types, one is qualitative, one is quantitative. Qualitative filter paper generally refers to the generation of cotton fiber on its surface after filtration, which is generally only suitable for qualitative analysis.
While the quantitative filter paper is generally for the non-ash filter paper, in the process of use must go through a special processing program, to a certain extent, it can effectively resist some chemical reactions, so the generated impurities on its surface will be much less, it is generally used in quantitative analysis.
In addition to the application of filter paper in chemical experiments, there are also applications of filter paper in our daily life. For example, the coffee filter paper is one of the most widely used. In general, this filter paper has high softness, while in industry, the filter paper is generally used to absorb suspended particles in the air.
