Removal of cationic dye using polyvinyl alcohol membrane functionalized by D-glucose and agar
The composite membranes of polyvinyl alcohol (PVA) functionalized by d-glucose and agar using the solution casting method were prepared for dye wastewater treatment. The composite membranes improved their hydrophobicity and thermal stability with respect to the parent PVA. The membranes possess good...
