Title:
MAGNETIC ALUMINUM-BASED ADSORBENT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/093188
Kind Code:
A1
Abstract:
Disclosed in the present invention are a magnetic aluminum-based adsorbent and a preparation method therefor. The preparation method comprises the following steps: mixing a carbon black slag powder, porous aluminum oxide and a polar solution, calcining same, then mixing the magnetic powder with a cross-linking agent, then injecting same into a forming mold for treatment and formation, then stripping same, and activating same, so as to obtain the magnetic aluminum-based adsorbent. The magnetic aluminum-based adsorbent prepared by the preparation method has a relatively high adsorption property and can adsorb low-concentration metal ions in wastewater generated by wet recovery of waste batteries well.
