Iridium oxide is a precious platinum group metal that is widely used in catalysts, electronic devices, high-temperature equipment and other fields. The use of iridium oxide can not only save resources, but also reduce environmental pollution. However, the process of iridium oxide is not simple, and suitable methods and techniques need to be adopted, otherwise various problems and difficulties will be encountered. This article will introduce the problems that may arise in the process of iridium oxide and their solutions from both physical and chemical aspects.
First of all, from a physical point of view, the process of iridium oxide requires steps such as high-temperature smelting and electrolytic refining, which require a lot of energy, and also produce a certain amount of waste gas, waste water and waste residue, which has an impact on the environment. Therefore, the process of iridium oxide needs to optimize energy efficiency, reduce energy waste, and also strengthen the treatment of waste gas, waste water and waste residue to avoid environmental pollution. In addition, the process of iridium oxide also needs to pay attention to preventing the volatilization and loss of iridium, because iridium will have a certain volatility at high temperatures, and if there is no effective collection and ** measures, it will lead to the loss and waste of iridium. Therefore, the process of iridium oxide needs to adopt closed equipment and systems to prevent the volatilization and loss of iridium and improve the rate and purity.
Secondly, from a chemical point of view, the process of iridium oxide requires steps such as chemical reduction, solvent extraction, and ion exchange, which require the use of various chemical reagents and solvents, which will not only increase the cost, but also have an impact on the effect and quality of iridium oxide. Therefore, the process of iridium oxide needs to choose appropriate chemical reagents and solvents, avoid the use of excessive or unnecessary chemical reagents and solvents, and also pay attention to controlling the reaction conditions, such as temperature, pressure, pH value, redox potential, etc., to ensure the effective reduction and separation of iridium oxide, and avoid side reactions and impurities. In addition, the process of iridium oxide also needs to pay attention to preventing the oxidation of iridium oxide and the regeneration of oxides, because iridium oxide will have a certain oxidation in the air, and if there are no effective protective measures, it will lead to the oxidation of iridium oxide and the regeneration of oxides, reducing the efficiency and quality. Therefore, the process of iridium oxide needs to adopt an inert gas or vacuum environment to prevent the oxidation of iridium oxide and the regeneration of oxides, and maintain the reduced state of iridium oxide.
To sum up, the problems that may occur in the process of iridium oxide are mainly as follows: energy consumption, environmental pollution, iridium volatilization and loss, the influence of chemical reagents and solvents, the oxidation of iridium oxide and the regeneration of oxides, etc. These problems need to be optimized by adopting appropriate methods and technologies to improve efficiency and quality, and to achieve the efficient use of iridium oxide.
