Abstract

The invention relates to the technical field of water purifying agent preparation, and discloses a polyaluminum chloride pharmaceutical composition and a preparation method thereof. The polyaluminum chloride pharmaceutical composition comprises the following raw materials in parts by weight: 30-40 parts of polyaluminum chloride, 10-15 parts of polyaluminum sulfate, and 10-15 parts of ferric sulfate. The polyaluminum chloride pharmaceutical composition is prepared by carrying out microencapsulation treatment on polyaluminum chloride, polyaluminum sulfate and ferric sulfate by using a chitosan solution, wherein the chitosan solution is prepared by dissolving modified chitosan in an acetic acid solution; and arc pair electrons on nitrogen in modified chitosan molecules and cuprous ions are chemically adsorbed on a copper pipeline to form a protective film, meanwhile, metal ions and triazole ring electrons form a sigma coordination bond, and a d orbital filled with the metal ions I provides electrons to a triazole symmetrical empty orbital to form a feedback pi bond, so that a crystal field is split, molecular orbital energy is reduced, the stability of the protective film is improved, corrosion of a copper pipeline is prevented, and water pipe corrosion caused by too high corrosion of polyaluminum chloride is avoided.

Description

technical field [0001] The invention relates to the technical field of water purifying agent preparation, in particular to a polyaluminum chloride agent composition and a preparation method thereof. Background technique [0002] The lack of water resources has always been a major problem facing our country, especially in recent years with the rapid development of the domestic economy, water consumption has risen sharply, and water pollution has become increasingly serious. Industrial water treatment technology is very important for saving water resources, reducing water pollution, It is of great significance to prolong the service life of equipment; [0003] Therefore, with the continuous improvement of industrial water treatment and environmental protection requirements, the variety of water treatment agents in my country has been continuously enriched and their performance has been continuously improved. To the diversified development of compounding, in specific practical ...
