1. Ammonium alum plays an important role in water purification. After it dissolves in water, it ionizes to produce Al3+, and Al3+ combines with OH- produced by hydro-ionization to produce aluminum hydroxide. Aluminum hydroxide colloidal particles with positive charge meet with negatively charged sediment colloidal particles, and their charges are neutralized. The charged colloidal particles will soon coalescence together and eventually sink to the bottom, making the water clear and clean.
2. The tannery industry is used as an aluminum tanning agent and a post-treatment agent for skin nitrification, which helps to improve the quality and performance of leather.
3. The dye industry is used as an anti-stain agent, which helps to control the diffusion and fixation of the dye and improve the dyeing effect.
4. The paper industry is used as a dye for paper sizing, which helps to improve the surface properties and printing performance of paper.
5. The glass industry is used as a colorant for yellow glass to give the glass a specific color.
6. In the field of medicine, it has the effect of detoxifying and killing insects, relieving dampness and itching, stopping bleeding and diarrhea, clearing heat and eliminating phlegm. Some Chinese medicine practitioners use ammonium alum to treat diseases such as hyperlipidemia, duodenal ulcer and pulmonary hemoptysis.
7. In the food industry, ammonium alum is used as a buffer and leavening agent.
8. Used in pigment, electroplating, starch and other industrial sectors. For example, it can be used in the preparation of aluminum salts, paints, tanning materials, mordant, paper making, water repellent and so on.
9. Ammonium alum can also be used in various experimental research and development.
