preparation example Construction

[0042] The preparation method and performance of composite material CMC among the present invention are introduced as follows:

[0043] A kind of preparation method of composite material CMC, comprises the steps:

[0044] S1: the nano-Fe 3 o 4 Ultrasonic dispersion in a three-necked flask containing deionized water to form Suspension A;

[0045] Dissolve MOFs and CS in a beaker and stir well to form a stable suspension B. The mass ratio of MOFs and CS is 1:4 to 4:1. In practice, the mass ratio of MOFs and CS can be selected as 1:4 or 1:2 , 1:1, 2:1 or 4:1;

[0046] S2: According to Fe 3 o 4 The mass ratio of CS to CS is 1:4~4:1, inject the suspension B into the suspension A drop by drop, and stir rapidly to form a uniform and stable suspension, and then add pure N 2 The reaction solution is completely deoxygenated by bubbling, and during specific implementation, Fe 3 o 4 The mass ratio to CS can be selected as 1:4, 1:2, 1:1, 2:1 or 4:1;

[0047] S3: Add the initiator ...

Abstract

The invention relates to a method for removing antimony ions in a water body by a magnetic adsorption material. The method includes the following steps: S1: pretreating the water body: adjusting the pH value of the water body to make the water body alkaline; and / or diluting the water body to reduce the water body Medium pollutant concentration; S2: Add the composite material CMC to the water body and stir: the ratio of the dosage of the composite material CMC to the volume of the water body is: 0.2g / L~1.2g / L, the dosage of the composite material CMC The mass of the water body and the volume unit of the water body need to be on the same order of magnitude; then first stir rapidly for 0.5-3 hours, then stir slowly for 0.5-3 hours, and finally stand still for more than 30 minutes, and the external magnetic field separates the adsorbent. The composite material CMC can be stably distributed in the water body, and with good magnetic performance, it can be recycled and reused very well. Moreover, chitosan itself is green and non-toxic, and has a good adsorption effect. Using it as a carrier will not cause secondary pollution to water bodies.

Description

technical field [0001] The invention relates to the field of energy and environmental protection, in particular to a method for removing antimony ions in water by a magnetic adsorption material. Background technique [0002] With the rapid development of industry and agriculture, water pollution caused by heavy metals has become the focus of social attention. Antimony (Sb) is a toxic and potentially carcinogenic metal element that widely exists in the human living environment, and the pollution problem caused by antimony metal needs to be solved. Antimony pollution comes from a wide range of sources, for example: the mining and smelting of antimony can easily cause serious soil pollution near the site, which poses health threats to residents in surrounding areas; antimony and its compounds are widely used in various industrial products (such as ceramics , ammunition, glass, battery, paint, pyrotechnic material), the production process is accompanied by environmental polluti...
