MAGNETIC ADSORBENT BASED ON WASTE BIOMASS, PREPARATION METHOD THEREFOR, AND USE THEREOF

摘要

Disclosed are a magnetic adsorbent based on waste biomass, a preparation method therefor, and the use thereof. The adsorbent comprises the following components in parts by weight: 50-80 parts of a waste biomass powder, 1-3 parts of citric acid, 12-25 parts of sodium stearate, 5-25 parts of iron chloride, 2-5 parts of sodium molybdate, 12-25 parts of foamy copper, 1-3 parts of a spiro compound, and 20-28 parts of carboxymethylcellulose sodium, wherein the waste biomass powder is prepared by mixing a Spartina alterniflora straw powder, a peanut hull powder and a crayfish shell powder. In the present invention, by using solid biomass waste to treat dye wastewater, waste control by means of waste is achieved. In addition, the preparation process is simple, the cost is low, and the amount of environmental pollution is low; the adsorption treatment of dye wastewater with the prepared magnetic adsorbent achieves stable and ideal effects; and under an applied magnetic field, rapid separation and recovery can be achieved.
