Abstract

The invention relates to the technical field of water treatment and in particular relates to a heavy metal adsorbent. The heavy metal adsorbent is prepared from the following raw materials in parts by weight: wood charcoal, artificial zeolite, baking soda, sodium carbonate, a molecular sieve, coconut shells, graphene and plant extract. The plant extract is prepared from rorippa globosa, herba commelinae, rhizoma acori tatarinowii and cynodon dactylon according to the weight part ratio of 1 to 0.6 to 0.5 to 0.3. According to the heavy metal adsorbent, the rorippa globosa, the herba commelinae, the rhizoma acori tatarinowii and the cynodon dactylon in the plant extract are over-accumulated plants so that the heavy metal adsorbent can be used for effectively adsorbing heavy metal elements including Cd, As, Ni and Cu, is safe and has no toxin and does not cause secondary pollution; metallothionein in the heavy metal adsorbent can be used for further improving a metal storage capability. The raw materials are cheap and easy to obtain, the production cost is low and the adsorption effect is good.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a heavy metal adsorbent. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. For environmental protection, the treatment of industrial wastewater is more important than the treatment of urban sewage. Wastewater containing heavy metals is highly toxic and needs to be separated from other wastewater and treated separately. At present, the treatment methods of heavy metal wastewater mainly include adsorption method, chemical precipitation method, and catalytic oxidation method. Among them, the adsorption method of applying porous adsorption materials to adsorb heavy metals in wastewater through ion chelation and complexation is one of the most commonly used methods. However, t...
