Nano structure adsorption material capable of efficiently removing micro-pollutants and preparation method thereof

Abstract

The invention discloses a nano structure adsorption material capable of efficiently removing micro-pollutants and a preparation method thereof. The adsorption material is prepared from the following components in parts by weight: 20-25 parts of nano ferroferric oxide, 20-25 parts of nano titanium dioxide, 3-5 parts of fullerene and 3-5 parts of chitosan. The preparation method comprises the following steps of: weighing nano ferroferric oxide, nano titanium dioxide, fullerene and chitosan according to the amount of a formula; and mixing nano ferroferric oxide with nano titanium dioxide to obtain mixed powder, vibrating and stirring the mixed powder for 5 minutes, and standing for 1-2 minutes, and adding weighed fullerene and chitosan to mix to obtain the nano structure adsorption material.Compared with the prior art, the nano structure adsorption material disclosed by the invention has the following advantages that the nano structure adsorption material is simple in preparation method,is simple in component, is non-toxic, and is suitable for industrial large-scale production; adsorption efficiency on heavy metal and organic micro-pollutants in sewage is high, and adsorption performance is excellent; the specific surface area is relatively great; the size is uniform; the chemical properties are stable; and the dispersion is relatively good.

Description

technical field [0001] The invention relates to the technical field of adsorption materials, in particular to a nanostructure adsorption material for efficiently removing micro-pollutants and a preparation method thereof. Background technique [0002] With the rapid development of economy and society, environmental problems are becoming more and more severe, and water pollution is showing an increasing trend. The discharge of industrial, agricultural and domestic wastewater poses challenges to sewage treatment. At present, most wastewater treatment uses adsorbent materials to absorb pollutants for purification. Adsorbent materials commonly used in polluted water bodies include activated carbon, chitosan and other polymer adsorbents, microbial adsorbents, and mineral adsorbents. Such as arsenic, organic micro-pollutants such as perfluorooctane sulfonic acid, perfluorooctanoic acid, etc., the adsorption efficiency is not high, and the adsorption is poor.
