Embodiment Construction

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

[0014] A volcanic rock adsorbent with rare earth elements added, made of the following raw materials in parts by weight (kg): calcium carbonate fiber 12, tetrabutyl titanate 35, silica sol 4, calcium aluminate 7, volcanic rock 78, PA6 nylon powder 8 , gelatin 3, ammonium bicarbonate 2, cerium dioxide 7, attapulgite 6, appropriate amount of deionized water;

[0015] A kind of volcanic rock adsorbent that adds rare earth element described in 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 subse...

Abstract

The invention discloses a rare-earth element added volcanic rock adsorbent. The rare-earth element added volcanic rock adsorbent is characterized by being prepared from the following raw materials in parts by weight: 8-15 parts of calcium carbonate fiber, 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 nylon PA6, 3-4 parts of gelatin, 1-3 parts of ammonium bicarbonate, 5-8 parts of ceria, 5-7 parts of attapulgite and a proper volume of deionized water. According to the rare-earth element added volcanic rock adsorbent, the adhesive power among the raw materials is enhanced by the ceria and attapulgite added, and ceria and attapulgite have a good interaction effect, so that the adsorption property of the adsorbent is further strengthened, particularly the absorption of nitrogen and phosphorus elements; and the adsorbent disclosed by the invention has a good adsorption effect on various pollutants and is high in adsorption efficiency, easy to remove and good in reuse effect, a preparation method comprises few steps and is simple in process, and thus industrial production is facilitated.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to a volcanic rock adsorbent added with rare earth elements and a preparation method thereof. Background technique [0002] The scarcity of water resources has always been a major problem facing our country, especially in recent years with the rapid development of the domestic economy, the water consumption has risen sharply, and the pollution of water resources has become increasingly serious. Industrial water treatment technology is of great significance for saving water resources and reducing water pollution. Rare earth elements have special electronic structures and unique physical-chemical properties, which make them widely used in various fields. Studies in recent years have shown that the specific catalytic and adsorption properties of rare earths not only have unique and significant effects in industry and agriculture, but also play an irreplaceable role in water pollution contro...
