Zirconium titanium separation method

Zirconium titanium separation method

Zirconium titanium alloy is a kind of metal material with high strength and corrosion resistance, which is widely used in aviation, aerospace, Nuclear engineering, chemical industry and other fields. However, due to the similar chemical properties of zirconium and titanium in zirconium titanium alloys, it is difficult to effectively separate and purify them through traditional physical and chemical methods. Therefore, the zirconium titanium separation method has become a key link in the production process of zirconium titanium alloys. The main methods for selecting zirconium and titanium include the following: 1 Solvent extraction solvent extraction is a method that uses the difference of Partition coefficient of solvent in different solutions to achieve separation. In the production of zirconium titanium alloys, organic solvents (such as dimethylbenzene, benzoic acid) can be used for extraction with the aqueous phase to achieve the separation of zirconium and titanium. This method is simple to operate and efficient, but requires the use of a large amount of organic solvents, causing environmental pollution. 2. Ion exchange method Ion exchange method is a method of selective adsorption and desorption of ions using ion exchange resins. In the production of zirconium titanium alloy, strong acid ion exchange resin (such as sulfuric acid resin) can be used to absorb titanium ions, and then the zirconium ions can be desorbed by changing the pH value or using strong basic ion exchange resin (such as Aluminium hydroxide resin). This method has good separation effect, but it requires a large amount of chemical reagents, which poses certain harm to the environment and human health. 3. Oxidation reduction method Oxidation reduction method is a method of separation by Redox. In the production of zirconium titanium alloy, reducing agents such as sodium hydroxide or Aluminium hydroxide can be used to reduce titanium ions to Titanate, and then Titanate and zirconium ions can be separated by precipitation. This method is simple to operate and environmentally friendly, but requires a large amount of reducing agent, which has a certain impact on production costs. 4. Gas chromatography is a method of separating and detecting compounds in samples using a gas chromatograph. In the production of zirconium titanium alloys, gas chromatography can be used to separate and detect zirconium and titanium. This method is simple to operate and efficient, but requires the use of professional instruments, which has a certain impact on production costs. In summary, the zirconium titanium separation method is a key link in the production process of zirconium titanium alloys. Different sorting methods have their own advantages and disadvantages, and it is necessary to choose the appropriate method for separation and purification based on the specific situation. At the same time, in order to reduce the impact on the environment and human health, corresponding environmental protection measures need to be taken during the selection process.
