Problems solved by technology

This determines that there will be secondary pollution after chemical treatment, such as the generation of a large amount of waste residue, and there is no good disposal method for the treatment of these waste residues, so there is a huge impact on its application in engineering and sustainable development. Negative effects
[0004] The solvent extraction method in the physical chemical method, the loss of solvent in the extraction process and the large energy consumption in the regeneration process are the limitations of this method; the ion exchange method has low energy consumption, simple operation and good treatment effect, but the treatment cost is relatively high. high

Abstract

The invention relates to magnetic phenol formaldehyde-humic acid resin and a preparation method thereof. The preparation method for the magnetic phenol formaldehyde-humic acid resin comprises the following steps of adding a sulfonated sodium humate solution into water-soluble phenol formaldehyde resin, uniformly stirring the mixed solution, adding magnetic fluid, stirring for mixing, heating the mixed solution to 100 DEG C, performing cross-linking reaction for 30 to 90 minutes at constant temperature, activating the magnetic phenol formaldehyde-humic acid resin in a calcium acetate solution, filtering and drying. According to the magnetic phenol formaldehyde-humic acid resin and the preparation method thereof, the magnetic phenol formaldehyde-humic acid resin can be prepared, is high in Cu<2+> ion adsorption performance, and can be used for removing copper ions from wastewater; the resin adsorbed with the copper ions is easy to regenerate, and can be separated by adopting an external magnetic field.

Description

technical field [0001] The invention relates to an adsorption resin, especially a production method of a magnetic phenolic humic acid resin and its application in removing copper ions in industrial wastewater treatment. Background technique [0002] The discharge of industrial wastewater is the main source of water pollution, and the excessive discharge of heavy metal ions in the water is very harmful to the environment, and its pollution problem has attracted increasing attention. According to the nature of heavy metal ions in industrial wastewater, scientific and reasonable methods are adopted for treatment. "Common Treatment Methods for Heavy Metal Ions in Industrial Wastewater" in "Guangzhou Chemical Industry" 2011 Volume 39 Issue 5 "Common Treatment Methods for Heavy Metal Ions in Industrial Wastewater" discusses chemical methods, physical chemical methods and biochemical methods. Made a detailed elaboration. [0003] Chemical methods include chemical precipitation and...
