Facile fabrication of magnetic carboxymethyl starch/poly(vinyl alcohol) composite gel for methylene blue removal

•Magnetic carboxymethyl starch/poly(vinyl alcohol) (mCMS/PVA) hydrogel was prepared by a one-step method.•The mCMS/PVA exhibited high removal efficiency for cationic methylene blue dye.•Adsorption process of mCMS/PVA fitted pseudo-second-order model and Freundlich isotherm.•The mCMS/PVA presented go...
