This is a relatively cumbersome process. It usually requires preparing a beaker for holding the filtrate, filter paper for filtering, a funnel for holding the filter paper, and a funnel frame for supporting the funnel. These parts must be installed one by one and combined into a whole to filter the slurry. , very troublesome

specific Embodiment 1

[0014] Specific embodiment 1, soil extract is filtered

[0015] (1) Folding filter paper: Take a circular filter paper with a diameter of 11cm, fold it in half twice, and fold it into a 1 / 4 circle fan shape;

[0016] (2) Open the filter hopper: stretch the folded fan-shaped filter paper from the middle to become a conical filter hopper;

[0017] (3) Put the conical filter funnel on a 50ml tall beaker with the edge turned outward, and the upper edge of the filter paper is higher than the edge of the beaker;

[0018] (4) Fill the conical filter funnel made of filter paper with soil extract to filter;

[0019] (5) After filtering out a clear solution, throw away the filter funnel and filter residue.

specific Embodiment 2

[0020] Specific embodiment 2, wheat leaf homogenate is filtered

[0021] (1) Folding filter paper: Take a circular filter paper with a diameter of 16cm, fold it in half twice, and fold it into a 1 / 4 circle fan shape;

[0022] (2) Open the filter hopper: stretch the folded fan-shaped filter paper from the middle to become a conical filter hopper;

[0023] (3) Put the conical filter funnel on a 100ml tall beaker with the edge turned outward, and the upper edge of the filter paper is higher than the edge of the beaker;

[0024] (4) Fill the conical filter hopper made of filter paper with the wheat leaf homogenate to be filtered for filtration;

[0025] (5) After filtering out a clear solution, throw away the filter paper and filter residue.

Abstract

The invention discloses a filter paper filtering method in a chemical experiment. The method comprises the following steps: folding filter paper to be conical, directly putting the folded filter paper on a tall beaker, and filtering pulp. The method is easy to perform, convenient, quick and good in filtering effect, and few utensils are used.

Description

technical field [0001] The present invention relates to the method of chemical experiment, more specifically a kind of filter paper filtration method in chemical experiment. Background technique [0002] In routine chemical experiments, filter paper is often used to filter the slurry. This is a relatively cumbersome process. It usually requires preparing a beaker for holding the filtrate, filter paper for filtering, a funnel for holding the filter paper, and a funnel frame for supporting the funnel. These parts must be installed one by one and combined into a whole to filter the slurry. , very troublesome. Therefore, it is meaningful to create a filter paper filtration method without support and funnel to simplify the operation steps of chemical experiments and improve work efficiency. Contents of the invention [0003] The purpose of the invention is to propose a filter paper filtration method without funnel and support for the complex situation of filter paper filtrati...
