The relationship between mankind and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, chemical products are needed to serve them. Some chemical products have played an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. The products that the chemical industry provides to people are rich and colorful. In addition to producing a large amount of materials for making various products for human use, there are also products with a small amount but with very obvious effects, which continuously improve people's lives. Chemical equipment, including chemical equipment, all chemical machinery are tools used in chemical factories to realize chemical production. The normal operation of the production process of chemical products and the control and guarantee of product quality and output are inseparable from the adaptation and normal operation of various chemical equipment. The selection of chemical equipment must meet the needs of chemical production through careful calculation, design, processing, manufacturing and selection of the entire chemical production process. Solvent extraction is a method that uses organic solvents to extract and separate the extract from its immiscible aqueous solution. It is called organic solvent liquid-liquid extraction, or solvent extraction for short. It is a method of removing substances from one A mass transfer process in which a liquid phase is transferred to another liquid phase. Solvent extraction has been applied earlier in petrochemical, organic chemistry, medicinal chemistry and analytical chemistry. However, in the past 40 years, due to the development of atomic energy science and technology and the need for the production of ultra-pure substances and rare elements, solvent extraction has made great progress in nuclear fuel industry, rare metallurgy and other industries. my country has reached a very high level in the research of extraction theory, the synthesis and application of new extractants, and the extraction process of rare earth element separation.
