Article Synopsis
- Water pollution, especially from heavy metals like hexavalent chromium (Cr), poses a significant threat to human survival and highlights the need for effective solutions.
- Researchers developed self-floating Ni-FeLDH@MWCNT@CA microbeads that effectively remove Cr from water, with optimal performance achieved by increasing the proportion of MWCNTs to 5 wt%.
- The adsorption process of Cr on these microbeads was efficient and well-modeled, showing promising results for reusability and potential application in treating heavy metal-contaminated wastewater.
An efficient composite adsorbent was fabricated based on carboxymethyl cellulose (CMC) microbeads incorporated carboxylated graphene oxide (GOCOOH) for the adsorptive removal of cationic methylene blue dye (MB). The developed CMC/GOCOOH composite microbeads were characterized by means of FTIR, TGA, SEM, XPS, BET and zeta potential analysis tools. Various parameters affecting the removal of MB dye such as the amount of GOCOOH, initial MB concentration, adsorbent dosage, pH and medium temperature were optimized using a series of batch adsorption experiments.

The developed IDA@CMC-PBQ microbeads were characterized by FT-IR, TGA, SEM, XPS and zeta potential analysis tools. Ion exchange capacity measurements proved the successful generation of extra carboxylic groups on the surface of IDA@CMC-PBQ microbeads with a maximum value reached 3.
