Aluminium Chloride From Waste Aluminium Foil

Preparation of Polymeric Aluminium Chloride from Waste Aluminium Foils

Polymeric aluminium chloride is a commonly used inorganic polymer flocculant. The wide range of raw material sources for the production of polymeric aluminium chloride has laid the foundation for its development. Especially the production process of a variety of production processes for the development of polymeric aluminium chloride provides a convenient.

International and domestic production and application of inorganic polymer flocculants have reached a large scale, and the theoretical research has also made in-depth development. The raw materials for preparation mainly include the use of bauxite, aluminium hydroxide, waste molecular sieve catalysts, etc., and the preparation methods mainly include wet method and electrolysis method. Some scholars think that the waste aluminium foil has high economic value of recycling and reuse. He studied the optimal conditions for the preparation of polymeric aluminium chloride using waste aluminium foil and the scope of application for water purification through experiments.

With the development of industry and the rapid growth of urban population, the pollution of water resources is becoming more and more serious, and the sewage that needs to be purified and treated is also increasing, and the demand for water purification agents is increasing. As polymeric aluminium chloride molecules with varying numbers of hydroxyl groups, when polymeric aluminium chloride is added to the turbid source water, it continues to be hydrolyzed under the pH conditions of the source water, accompanied by a series of physical and chemical processes such as coagulation, adsorption, precipitation, etc., which can achieve the purpose of water purification.
