Glucose and chitosan are compounded on a hydrogel (GC hydrogel) by an initiator and a crosslinking agent, and GC hydrogel are applied to treat Co2+ in wastewater. The samples were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). In the study of adsorption process, the influence of five factors on the adsorption process was studied. On this basis, the adsorption thermodynamics, kinetics and adsorption mechanism of isotherm were discussed. The results showed that the adsorption capacities of GC hydrogels for Co2+ 202 mg g(-1) at 20 degrees C, pH = 7 and adsorbent dosage is 0.01 g. The study shows that the adsorption of heavy metal ions by GC hydrogel adsorbent is a single molecule chemisorption of the spontaneous process. In addition, GC hydrogel adsorbent has good cyclic stability. (C) 2019 Published by Elsevier B.V.
