Abstract

The invention relates to an adsorbent for efficiently adsorbing phosphate ions in water and a preparation method thereof. The invention mainly solves the problem of low removal efficiency of phosphate ions in industrial wastewater existing in the prior art. The present invention adopts the method of co-precipitation and hydrothermal treatment to prepare the metal composite Ca x Mg 6‑x Fe 2 (OH) 18 ·4H 2 O or Ca x Mg 6‑x Al 2 (OH) 18 ·4H 2 O, where x=1-5 is the technical solution of the adsorbent, which better solves this problem. The adsorbent prepared by the method of the invention has the characteristics of high efficiency in removing phosphate ions from water, and can be used in the field of environmental protection.

Description

technical field

[0001] The invention relates to an adsorbent for efficiently adsorbing phosphate ions in water and a preparation method thereof. Background technique

[0002] Phosphate ion (PO 4 3- ) is a common anion in the inorganic chemical industry, industrial wastewater, mine wastewater, surface water and drinking water, and its large amount has adversely affected chemical production, the environment and human health. Phosphorus is one of the main elements that cause eutrophication in water bodies. In order to effectively control the content of phosphorus in water bodies and prevent eutrophication of water bodies, phosphorus removal treatment must be carried out before the sewage from people's lives and production is discharged into rivers and lakes. Phosphorus removal technology by adsorption is attracting more and more attention because of its high efficiency, rapidity, no secondary pollution, and operation. The selection of adsorbents with low price, readily avail...
