Description
Summary:Recovery of gold ions from solution is most popular in the field of comprehensive recycling of secondary resources. Herein, we designed an efficient trithiocyanuric acid functionalized cellulose fiber adsorbent functionalized by covalent coupling of chloroacetyl chloride and trithiocyanuric acid for efficient recovery of gold ions from aqueous solution. The functionalized cellulose fibers were characterized by diverse instruments. The adsorption property of fibers was evaluated by different adsorption models. The maximum adsorption capacity is 340.42 mg/g at pH 4.0 at ambient temperature. The adsorption isotherm and kinetic models were in accord with the Langmuir and pseudo-second-order models, respectively, showing that the adsorption behavior was dominated by monolayer chemsorption. Langmuir and D-R models were agreed with the adsorption isotherm and pseudo-second-order kinetic model was best fitted with the adsorption kinetics. The results indicated that the functionalized cellulose fibers were a facile and efficient sorbent for recovery of gold ions.
