AI Technical Summary

Technical Problem

Existing technologies for treating halogen wastewater suffer from high treatment costs, technical difficulties, and unstable treatment results, leading to the need for multiple reprocessing of treated materials and potential environmental corrosion.

Method used

A resin@TiO2 composite material with a hollow core-shell structure is used to efficiently remove halogens through an electrophilic substitution reaction. The stability of the TiO2 shell is used to avoid corrosion between the material and metals or plastics. The composite material with uniform particles and good hydrophilicity is prepared by sol-gel method.

Benefits of technology

It achieves efficient and harmless treatment of halogens, and the material is stable at room temperature for a long time. It is suitable for storage in metal or plastic containers, reducing treatment costs and improving the stability of treatment results.
