In a recent case of platinum carbon catalyst recovery, we received a batch of platinum carbon samples for recycling. These samples appeared as black powders with high density, typical characteristics of platinum carbon catalysts. Used commonly in the chemical and pharmaceutical industries as reaction catalysts, their high density and fine particles indicate high platinum content and potential recycling value.
To confirm the authenticity of these platinum carbon catalysts, we employed a simple yet effective identification technique. By adding a small amount of sample into a dilute acid solution and observing for bubble formation, we could gauge reaction. Platinum carbon catalysts react under acidic conditions, releasing bubbles, serving as preliminary proof of their authenticity. Additionally, we further verified the presence of platinum in the samples through X-ray diffraction analysis.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47068.html
Based on the characteristics of the samples, we chose a suitable recovery process for the platinum carbon catalysts. Initially, the catalysts were treated with an acid wash to separate platinum from the carbon carrier. Then, platinum metal was extracted through chemical precipitation and filtration, with precise control of the concentration and duration of the acid wash to ensure maximum extraction rate and purity of platinum.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47068.html
Throughout the recovery process, every step is crucial. The acid wash process must be handled carefully to avoid loss of platinum metal. In the chemical precipitation step, the choice of precipitant and control of appropriate reaction conditions significantly affect the purity of the extracted platinum. Filtration and washing are key steps in enhancing the purity of the platinum metal. Finally, high-purity metallic platinum is obtained through thermal treatment or electrochemical purification.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47068.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47068.html
