Detailed Application of 4A Zeolite

1. Daily chemical ---- detergent additives: 4A zeolite as detergent additives is mainly used to exchange calcium ions in water to produce softened water, remove dirt and prevent dirt redeposition. At present, 4A zeolite is the most widely used and the most mature product in the substitution of phosphorus lotion aids. The substitution of 4A zeolite for sodium tripolyphosphate as detergent additive plays an important role in solving environmental pollution. 4A zeolite can also be used as a soap molding agent, toothpaste friction agent, etc.

2. Environmental protection ---- sewage treatment: 4A zeolite can remove NH3-N and Pb2+, Cu2+, Zn2+, Cd2+ in sewage. The wastewater discharged from industry, agriculture, civil and aquatic animal husbandry contains ammonia nitrogen, which not only endangers the survival of fish and pollutes the internal breeding environment, but also promotes the growth of algae, leading to the blocking of rivers and lakes. Due to the high selectivity of 4A zeolite to NH4+, it has been successfully applied in this field. Sewage from metal mines, smelters, metal surface treatment and chemical industry and other departments, which contains heavy metal ions are very harmful to human health. In addition to ensuring qualified water quality, 4A zeolite can also recover heavy metals.

3. Other uses:

(1) water treatment ---- hard water softener, can replace the sulfonated coal widely used in our country at present, so as to reduce costs;

(2) metallurgical industry ---- separation agent, separation and extraction of potassium, rubidium, cesium and so on in brine. In industry for enrichment, separation and extraction of metals and other processes;

(3) petrochemical industry ---- catalyst, desiccant, adsorbent;

(4) Agriculture ---- Soil amendments;

(5) medicine ---- silver - loaded zeolite antibacterial agent.
