Abstract

In light of the challenge associated with recovering platinum from platinum-containing waste using ion exchange techniques, there is a need to enhance the process of platinum adsorption. To address this, the ultrasonic strengthening method has been employed to improve the adsorption efficiency. Through the application of ultrasound, various resins were utilized to extract platinum metal from platinum-containing chloride leaching solution, with the identification of the most effective resin. The resin underwent characterization using diverse methods, and the adsorption mechanism was scrutinized. Findings indicated that the optimal ultrasonic power level was 240 W. In comparison to the traditional 12-h adsorption saturation period, dynamic equilibrium could be achieved within 3 h under ultrasonic conditions, with a maximum static adsorption saturation of 30.62 mg/g. The most favorable pH value was determined to be 1. The adsorption process of platinum on the resin was accurately described by the pseudo-second-order kinetic model. The 717 resins exhibited notable selectivity and reusability, maintaining an adsorption rate above 91.24% even after 5 regeneration cycles. In conclusion, ultrasound as a reinforcement method offers a viable approach for the practical recovery of precious metals.

离子交换法超声回收氯化铂溶液的研究

鉴于使用离子交换技术从含铂废物中回收铂所面临的挑战，有必要加强铂吸附过程。为了解决这一问题，采用超声强化法提高吸附效率。通过超声波的应用，利用各种树脂从含铂氯化物浸出液中提取铂金属，并鉴定出最有效的树脂。用不同的方法对树脂进行了表征，并对吸附机理进行了研究。结果表明，最佳超声功率为240 W。与传统的12 h吸附饱和周期相比，超声条件下3 h即可达到动态平衡，最大静态吸附饱和度为30.62 mg/g。确定最适宜的pH值为1。拟二级动力学模型准确地描述了铂在树脂上的吸附过程。717树脂具有明显的选择性和可重复使用性，即使经过5次再生循环，吸附率仍保持在91.24%以上。综上所述，超声作为一种强化方法为贵金属的实际回收提供了一条可行的途径。
