Insights and perspectives of chitosan-based hydrogels for the removal of heavy metals and dyes from wastewater.

Water pollution has become an increasingly serious issue, necessitating the design and development of more effective wastewater treatment methods. Chitosan-based hydrogels, owing to their unique structural and chemical properties, have demonstrated high efficiency in removing contaminants. However, the application remains restricted by the scarcity of effective adsorption sites and limited environmental stability.

Efficient Degradation of Congo Red in Water by UV-Vis Driven CoMoO/PDS Photo-Fenton System.

In order to improve the catalytic activity of cobalt molybdate (CoMoO), a PDS-activated and UV-vis assisted system was constructed. CoMoO was prepared by coprecipitation and calcination, and characterized by XRD, FTIR, Raman, SEM, TEM, XPS, TGA Zeta potential, BET, and UV-Vis DRS. The results showed that the morphology of the CoMoO nanolumps consisted of stacked nanosheets.

Chemiluminescence noncompetitive immunoassay based on microchip electrophoresis for the determination of β-subunit of human chorionic gonadotropin.

In this work, a microchip-electrophoresis chemiluminescence (MCE-CL)-based immunoassay method was established for the determination of β-subunit of human chorionic gonadotropin (β-HCG). This approach uses MCE-CL assay as a platform. First, the β-HCG antigen (Ag) binds to excess horseradish peroxidase (HRP)-labeled anti-β-HCG antibodies (Ab*) to form an immune complex (Ag-Ab).
