Embodiment Construction

[0013] The present invention will be described in detail below through specific examples.

[0014] A composite volcanic rock adsorbent, made of the following raw materials in parts by weight (kg): calcium carbonate fiber 12, ferroferric oxide magnetic powder 7, tetrabutyl titanate 35, silica sol 4, calcium aluminate 7, volcanic rock 75, PA6 nylon powder 7, gelatin 3, ammonium bicarbonate 2, vermiculite powder 6, deionized water;

[0015] A kind of composite volcanic rock adsorbent of the present invention is made by following specific steps:

[0016] (1) Mix tetrabutyl titanate with 4 times the amount of absolute ethanol, stir magnetically for 1 hour, chop calcium carbonate fibers and add them to the above solution, continue magnetic stirring for 2 hours, slowly add deionized water dropwise, and wait for the formation of Continue to stir for 0.6 hours after the gel, then add it to an oven for drying and grinding at 80°C for subsequent use;

[0017] (2) Soak the volcanic rock...

Abstract

The invention discloses a composite volcanic rock absorbent which is characterized in that the absorbent is prepared from the following raw materials, by weight: 8-15 parts of calcium carbonate fiber, 6-8 parts of iron tetroxide magnetic powder, 20-40 parts of tetrabutyl titanate, 3-5 parts of silica sol, 6-8 parts of calcium aluminate, 60-80 parts of volcanic rock, 6-9 parts of PA6 nylon powder, 3-4 parts of gelatin, 1-3 parts of ammonium bicarbonate, 5-8 parts of vermiculite powder, and deionized water. According to the invention, with the added vermiculite powder and iron tetroxide magnetic powder, volcanic rock absorbability, high-temperature resistance and fire resistance are enhanced; and an absorption range is expanded. The absorbent provided by the invention has good absorption characteristics in various fields and especially in the aspects of sewage treatment, oil pollution treatment and the like. The absorption efficiency is high, and the absorbent is easy to remove. The absorbent has a good reutilization effect, and has a good application prospect.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to a composite volcanic rock adsorbent and a preparation method thereof. Background technique [0002] With the development of social economy, the damage to the environment by various industries is becoming more and more serious, especially the pollution of natural water bodies is increasing day by day. Sewage discharged from the paper industry, textile industry, chemical industry, and steel industry enters natural water bodies, affecting the self-purification ability of natural water bodies and the growth of animals and plants in the water. Adsorption is an effective and fast method to protect water quality. Traditional adsorbents have short service life, poor reusability, low adsorption efficiency, etc., and the removal effect on sewage is not ideal. [0003] The texture of volcanic rock is as hard as natural stone. The surface of the coating is honeycomb porous and has a large specifi...
