AI Technical Summary
Traditional adsorbents are ineffective at adsorbing and separating multiple metal elements in copper-containing sludge, leading to cross-contamination of metal elements. Existing technologies are unable to effectively recover valuable elements.
The treatment of copper-containing sludge using Ti-MOFs materials includes steps such as dewatering, acid leaching, pretreatment, oxidation, precipitation, and extraction. Through the selective adsorption and modification of Ti-MOFs, combined with precipitation and extraction methods, multi-metal cascade purification is achieved.
It improves the recovery rate and purity of various metal elements, solves the problems of competitive adsorption and cross-contamination of metal elements caused by traditional adsorbents, and achieves efficient separation and recovery of multiple metals.
