Platinum-Iridium Recovery_Extraction of Platinum-Iridium Metals from Radiofrequency Ablation Catheters

Impact of Radiofrequency Ablation Catheter Models and Types on Platinum-Iridium Metal Extraction

Radiofrequency ablation catheters are medical devices used in cardiac electrophysiology research and treatment. The model and type of the catheter affect the extraction process of platinum-iridium metals. Different models have variations in design, materials, and manufacturing processes, which determine the content and extraction difficulty of platinum-iridium metals. Some high-end models contain higher proportions of platinum-iridium alloys, making metal extraction more valuable. Therefore, it is essential to understand the specific model and structure of the catheter during the recovery process and optimize the extraction process to improve the recovery rate of platinum-iridium metals.

Pre-treatment Steps Before Separation and Extraction of Platinum-Iridium Metals

The first step in the recovery process is to classify and disassemble the radiofrequency ablation catheters. Mechanical disassembly and chemical processing steps separate the metals from other materials (such as plastics and electronic components) to obtain parts containing platinum-iridium metals. Then, a crushing process is carried out to reduce the particle size of the platinum-iridium metals, facilitating the subsequent chemical extraction process.

Chemical Purification and Recovery Process of Platinum-Iridium Metals

After pre-treatment, the next step is chemical purification. This step involves dissolving the platinum-iridium metals from other materials, typically using acids or other chemical reagents. During the extraction process, precisely controlling the conditions of the chemical reaction (such as temperature, concentration, and pH) is crucial. Pure platinum-iridium metals are extracted from the solution through chemical precipitation or electrochemical purification methods.
