摘要：

The recovery of Au(III) has become a focal point of interest due to its significance in resource utilization and addressing environmental contamination. In this study, [C(3)NH(2)Mim]Cl-CMPS and PPh3-CMPS were successfully developed by immobilizing [C(3)NH(2)Mim]Cl and triphenylphosphine (PPh3) onto chloromethylated polystyrene beads (CMPS). The adsorbents demonstrated consistently high adsorption efficiency (>95 %) at a wide pH range. The [C(3)NH(2)Mim]Cl-CMPS and PPh3-CMPS exhibited exceptional selective adsorption ability for Au(III), and the adsorption process adhered to the PSO and Langmui...
