Facile preparation of MoS2@Kaolin composite by one-step hydrothermal method for efficient removal of Pb(II)

Weiquan Yuan et al.

Summary: MoS2@Kaolin composite material shows efficient, rapid, and highly selective adsorption of Pb(II). The adsorption process follows the Langmuir isotherm model with a maximum adsorption capacity of 280.39 mg/g. Additionally, the adsorption kinetics of MoS2@Kaolin to Pb(II) fits well with the pseudo-second-order kinetics models.

Comparative study on intercalation-exfoliation and thermal activation modified kaolin for heavy metals immobilization during high-organic solid waste pyrolysis

Haoran Du et al.

Summary: With the implementation of China's new municipal solid waste classification policy, attention has been focused on achieving waste-to-energy disposal of dry waste. Pyrolysis conversion of high-organic solid waste is a promising method for treating solid waste. The addition of kaolin as an additive during pyrolysis can effectively immobilize and stabilize heavy metals, with effective solid enrichment performance observed between 450-650 degrees Celsius.

Preparation of pH-sensitive carboxymethyl cellulose/chitosan/alginate hydrogel beads with reticulated shell structure to deliver Bacillus subtilis natto

Mengmeng Wang et al.

Summary: A novel strategy was designed to construct a pH-sensitive hydrogel structure that is stable in simulated gastric fluid but breaks down in simulated intestinal fluid. The structure showed a high embedding rate of Bacillus subtilis natto and sustained release for over 10 hours, balancing the conflicting properties of pH sensitivity and sustained release.

In Situ Functionalization of Iron Oxide Particles with Alginate: A Promising Biosorbent for Retention of Metal Ions

Alina-Roxana Lucaci et al.

Summary: In this study, alginate extracted from marine algae biomass was used to functionalize iron oxide particles, resulting in the preparation of a new biosorbent. The obtained Alg-Fe3O4-MPs showed high biosorption capacity for Cu(II), Co(II) and Zn(II) ions. The Langmuir model was found to be the best fitted model for the equilibrium data, and biosorption kinetics followed the pseudo-second order model.

Enhanced flotation selectivity of fine coal from kaolinite by anionic polyacrylamide pre-conditioning

Wencheng Xia et al.

Summary: The flotation process of fine non-coking coal from kaolinite was improved by the addition of anionic polyacrylamide, which interacted with kaolinite and coal particles through hydrogen bonding. Anionic polyacrylamide selectively flocculated kaolinite particles, reducing kaolinite pollution in the froth and decreasing the amount of kaolinite particles coating the clean coal surface. Ultimately, the flotation selectivity was enhanced by anionic polyacrylamide pre-conditioning.
