Preparation of hyperbranched polyetheramine-grafted GO adsorbent used for heavy metal and dye adsorption as well as application thereof

Abstract

The invention relates to a preparation method of a hyperbranched polyetheramine-grafted GO adsorbent used for heavy metal and dye adsorption as well as an application thereof. The hyperbranched polyetheramine-grafted GO adsorbent is characterized in that polyether diglycidyl ether and a polyamine monomer are employed to prepare the hyperbranched polyetheramine HPEA, an alkalescence catalyst grafting oxidation graphene GO is used, so that the hyperbranched polyetheramine-grafted oxidized graphene GO-HPEA. The adsorbent preparation method is simple and easy, the adsorption quantity for the heavy metal ion or cation dye can be more than 500mg / g, and the hyperbranched polyetheramine-grafted GO adsorbent has the advantages of easy solid-liquid separation and repeatable utilization, and can be used for high efficiency treatment of heavy metal and dye in waste water.

Description

technical field

[0001] The invention belongs to the technical field of water treatment, and in particular relates to a preparation method of a hyperbranched polyetheramine grafted GO adsorbent used for heavy metal and dye adsorption and an application technology for heavy metal ion and dye adsorption in water treatment. Background technique

[0002] Although the rapid development of emerging industries has brought great convenience to people's lives, industrial wastewater, especially wastewater containing a large amount of heavy metal ions or dyes, flows into rivers and lakes, causing serious pollution to water resources and threatening the economy. sustainable development and the healthy existence of human beings. Therefore, how to efficiently treat wastewater containing a large amount of heavy metal ions or dyes has attracted more and more attention, and this has become the focus and difficulty of wastewater treatment today. Currently known methods for treating wastewater...
