Problems solved by technology

Although conventional porous mineral materials have been used to remove heavy metal ions from the environment, these materials have limitations due to low loading capacity and low selectivity
Although the original microorganisms and agricultural, forestry and fishery wastes have a certain adsorption capacity, due to the low content of active components, the adsorption capacity is limited, and they usually need to be treated before they can be applied to the removal of heavy metal ions.

Abstract

The invention provides a clomiphene polymer capable of adsorbing heavy metal ions. The preparation method of the clomiphene polymer comprises the steps of enabling polyphenol and a diamine compound to react according to the mole ratio of 1 to (0.7-1.1) in ethyl alcohol, distilled water or a mixed solvent of ethyl alcohol and distilled water, centrifuging, washing and drying. The clomiphene polymer is low in price, is simple in experiment preparation method, and is convenient to operate; no additive is required, the reaction for oxidizing phenol into quinine can be completed only depending on oxygen in air, and further the polymerisate is obtained. The clomiphene polymer obtained by experiment is used for adsorbing heavy metal ions, and because of good adsorption performance, the clomiphene polymer has the potential of being widely applied to the field of heavy metal ion adsorption.

Description

technical field [0001] The invention relates to a preparation method and application of a phenolic amine polymer capable of adsorbing heavy metal ions. Background technique [0002] With the development of society, people's living standards are getting higher and higher, but the ensuing environmental pollution problems are also becoming more and more serious, especially in recent years with the development of industry, the problem of heavy metal pollution has become increasingly serious. The accumulated accumulation in the ecosystem has led to the deterioration of the environment, and has become a major killer affecting people's health. [0003] There are many existing methods for the removal of heavy metal ions, such as electrodeposition, filtration, ion exchange, membrane filtration, evaporation, reverse osmosis, and adsorption. Compared with other methods, adsorption method has many advantages such as less environmental pollution, fast adsorption rate, high efficienc...
