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.

在二次资源的综合回收领域中，从溶液中回收金离子最为普遍。在此，我们设计了一种有效的三硫氰尿酸官能化的纤维素纤维吸附剂，该吸附剂通过氯乙酰氯和三硫氰尿酸的共价偶联功能化，可以从水溶液中有效回收金离子。功能化的纤维素纤维由多种仪器表征。通过不同的吸附模型评价纤维的吸附性能。在环境温度下，pH 4.0时最大吸附容量为340.42 mg / g。吸附等温线和动力学模型分别与Langmuir模型和拟二阶模型一致，表明吸附行为受单层化学吸附支配。Langmuir和DR模型与吸附等温线相吻合，伪二级动力学模型最适合吸附动力学。结果表明，功能化纤维素纤维是一种用于金离子回收的简便有效的吸附剂。
