Two mainstream methods of platinum and rhodium wire recycling

Platinum-rhodium wire is used in precision instruments, temperature sensors and other fields. With the development of science and technology and the scarcity of resources, the recycling of platinum-rhodium wire has become more and more important. At present, there are two main mainstream methods for recycling platinum and rhodium wire: chemical treatment and electrochemical treatment.
The first is the chemical treatment method, which is a traditional platinum-rhodium wire recycling method. The metal elements in the platinum-rhodium wire are converted into soluble forms through chemical reactions, and then the platinum-rhodium metal is recovered from the solution through precipitation, filtration and other steps. element. This method is low-cost and relatively simple to operate, but it is prone to environmental pollution during the treatment process, and the recovery rate and purity of platinum and rhodium are limited by chemical reagents and reaction conditions.

The other is electrochemical treatment, which is a more advanced platinum and rhodium wire recycling technology developed in recent years. It applies current to a solution containing platinum and rhodium, causing the metal elements platinum and rhodium to precipitate on the electrode to form a precipitate. The advantage of this method is that it can more accurately control the recovery process of platinum and rhodium, improving recovery rate and purity. Compared with chemical treatment, electrochemical treatment is more environmentally friendly, but the equipment and operating costs are relatively high.
In the field of platinum and rhodium wire recycling, these two methods have their own advantages and disadvantages. Chemical treatment has always been a common choice for platinum and rhodium wire recycling due to its economy and simplicity of operation. However, with the improvement of environmental protection requirements and technological advancement, electrochemical treatment is gradually becoming a trend in platinum and rhodium wire recycling due to its higher efficiency and environmental protection.
