Composite absorption material capable of removing phosphate radical in water as well as preparation method thereof

Abstract

The invention discloses a novel efficient composite absorption material prepared by loading modified wheatgrass straw negative ions on an egg shell membrane, and belongs to the field of water treatment. The invention also discloses a method for removing phosphate radical in water by utilizing the egg shell membrane loaded with the modified wheatgrass straw negative ions, namely, the composite absorption material can be used for absorbing and removing phosphate radical ions in water under a neutral condition. The novel efficient composite absorption material can be used for effectively absorbing the phosphate radical ions in the water, and solves the pollution problem of the phosphate radical fundamentally. The novel efficient composite absorption material has the characteristics of large specific surface area, high absorption efficiency, availability of raw materials, low material cost, high recovery rate and the like, is simple to operate, and is low in cost, and materials can be obtained easily, so that the novel efficient composite absorption material capable of removing the phosphate radical ions in the water, provided by the invention, has favorable economic and environment benefits.

Description

technical field [0001] The invention relates to a composite adsorption material for removing phosphate radicals in water and a preparation method thereof, in particular to a novel material prepared by loading modified wheat straw anions on an eggshell membrane film, and belongs to the field of water evolution treatment. Background technique [0002] The excess of phosphate ions has been recognized as the main factor of eutrophication and cyanobacteria surface water, usually phosphate is discharged into the water system from washing process, pigment configuration, water treatment and other ways. High phosphorus content causes algae to proliferate and accumulate, destroying the water quality of the receiving water body and affecting the landscape function of the water body, and the highly toxic biotoxins produced by the excessively proliferating blue-green algae will affect human health. [0003] At present, the methods used to remove phosphate ions in wastewater mainly includ...
