Study on Removal of Methylene Blue by Condensation Self-Assembled Graphene Oxide/Thiourea Composite Adsorbent

A novel adsorbent (GO-TOA) was prepared by condensation and self-assembly of graphene oxide (GO) thiourea, it characterized systematically. The results revealed that thiourea has anchored on successfully. showed GO-TOA had a higher adsorption capacity (641.724 mg/g) rate (92.32%) than GO (196.8 mg/g 65.6%), indicating the introduction greatly improved GO. Adsorption kinetics, thermodynamics isotherm, were used to study mechanism. show still an 90.44% compared with 0 cycles (92.32), good activation regeneration capacity. In addition, ethanol dilute hydrochloric acid for desorption MB, effect found very well. Through reusability experiments, we also excellent application potential. We believe will be potential MB.
