Abstract

The invention discloses a method for preparing a simple semipermeable membrane separation device. The method comprises the following steps: S1, drilling holes in eggs; S2, preparing eggshells; S3, conducting soaking and dissolving; and S4, preparing the separation device. The simple semi-permeable membrane separation device prepared by the method plays an important role in colloid and semi-permeable membranes in high school chemistry teaching research, the preparation method is simple, easy to operate and low in cost, experiments are performed by the simple semi-permeable membrane separation device, the phenomenon is accurate, errors are not easy to occur, the interest of students in chemistry can be stimulated, and the device has important significance for guiding students to carry out scientific experiments.

Description

technical field [0001] The invention relates to the technical field of semipermeable membranes, in particular to a method for preparing a simple semipermeable membrane separation device. Background technique [0002] Chemical experiment is an important step to guide students in the teaching process. Carrying out experimental teaching can stimulate students' interest in learning chemistry, cultivate students' scientific attitude and learning methods, and cultivate students' creative spirit and scientific literacy. At the same time, strengthening chemistry experiment teaching is an important link to improve the quality of chemistry teaching. It can be seen that chemical experiments play a decisive role in chemistry teaching. Semipermeable membranes are needed when separating solutions and colloids and studying the properties of colloids in current high school chemistry experiments. However, the laboratory does not have a special semi-permeable membrane, and factors such as t...
