Introduction to Cations Adsorption

Native and modified yam starches’ granules size were normally distributed except bitter yam starch FTIR revealed additional bands and molecular rearrangements were introduced due to modifications Adsorption isotherms revealed type III, GAB-model isotherms with low monomolecular moisture.

The proposed Cu(II) cations adsorption mechanism was electrostatic adsorption, while Cr(VI) were possibly complexed by the phenolic -OH and reduced to Cr(III) cations by CC groups in HS-PVC.

Although MXenes exhibit exciting potential in cations adsorption due to their unique surface groups, the adsorption capacity is limited by the low specific surface area and undeveloped porosity.

Heavy metal cations adsorptions were studied in optimum conditions and the residual concentration of heavy metal cations was measured by ICP.

Combining high selenium adsorption capacity, rapid adsorption kinetics, and suitable adsorption pH, Cu-Al2O3/ceramic particles have potential applications adsorption.

In this work, Br-doped CuO multilamellar mesoporous nanosheets with oxygen vacancies and cetyltrimethyl ammonium (CTA+) cations adsorption were synthesized on Cu foam by one-step liquid-phase method at room temperature.

Study of Pb2+ cations adsorption on these samples proved the high affinity of the pinecones derived ACs to this cation.

Reusability data suggests that (BCS) adsorbents retained ≥ 90% of their initial cations adsorption, these adsorbents may be reusable in wastewater treatment.

From XPS analysis, it was revealed that the external surface of oxidized biochar particles becomes saturated for the initial point of equilibrium diagram, obtained at lead initial concentration of 100gm-3, suggesting that for a higher concentration, the internal surfaces of particles participate in the cations adsorption.

Increasing the ammonium persulfate (APS) concentration did not change significantly the dyes and metal cations adsorption.
