Potassium aluminum sulfate is used for chemical oxidation of sulphate galvanizing, brush galvanizing and magnesium alloys, and can also be used as a coagulant for treating sewage. If used for galvanizing, it is necessary to pay attention to the content of iron and heavy metals.
Aluminum Sulfate Anhydrous is an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation.
The aluminum hydroxide (Al(OH 3)) that is produced in this reaction is then heated to drive off water, producing aluminum oxide. Wastes from coal mining operation are also treated to extract the aluminum sulfate (Al 2 (SO 4) 3) they contain. The aluminum sulfate is converted to aluminum hydroxide which, again, is heated to produce aluminum oxide.
