摘要：

A series of high-performance montmorillonite nanosheets (MMTNS)-based hydrogel beads (HG-Bs) are prepared with different amounts of MMTNS, acrylic acid, acrylamide, sodium alginate and polyvinyl alcohol. MMTNS can significantly enhance the adsorption performance and structural strength, showing porous structure, good reusability, and high adsorption capacity of 564.97 mg/g for methylene blue. Moreover, FTIR, EDS and XPS measurements indicate that methylene blue is adsorbed by HG-Bs mainly through the adsorption between methylene blue and carbox...
