Laboratory fast speed qualitative filter paper for chemical

Qualitative analysis of filter paper generally residual ash more, only for general qualitative analysis and used for filtration precipitation or suspension in solution, can not be used for quality analysis.
Qualitative analysis of filter paper type and specification and quantitative analysis of filter paper is basically the same, fast, medium and slow, but printed on fast, medium and slow words said. However, in the case of filter paper is not the use of quantitative and qualitative analysis of filter paper filter should pay attention to precipitation:
1. Natural filtration, using filter paper and the ability to retain solid particles, so that the separation of liquid and solid;
2. due to the poor mechanical strength and toughness of filter paper, use less as far as possible the filtration way to filter, if it is necessary to accelerate the speed of filtering, to prevent wear filter filtration caused by failure, in the air pump filter, according to the pumping force in the funnel stack put 2 ~ 3 layers of filter paper, in vacuum, in leakage. First pad a layer of dense cloth on top filter paper;
3. Filter paper is best not to filter the hot concentrated sulfuric acid or nitric acid solution.
