Summary: To improve the removal efficiency of Cr (VI) by chitosan, this study successfully synthesized a Zr4+ and glutaraldehyde crosslinked polyethyleneimine functionalized chitosan (CGPZ) composite. The adsorption process of Cr (VI) by CGPZ was found to be a spontaneous endothermic process controlled by entropy. The adsorbent showed good acid-base resistance and regeneration performance. CGPZ can synergistically adsorb Cr (VI) through electrostatic interaction and ion exchange, and then reduce Cr (VI) to Cr (III) and chelate Cr (III) through specific functional groups.

Summary: This study found that Bi2S3 nanoparticles prepared from dual sulfur sources efficiently remove Cr(VI) and Cu2+ from aqueous solutions. The selectivity and stability of the removal process for Cr(VI) and Cu2+ by BS-D were excellent. The mutual promotional effects between Cu2+ and Cr(VI) during their co-removal by BS-D were attributed to electrostatic attraction and smaller pH variation.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
