2. Wastewater treatment: FeCI3 can be used for the treatment of raw water with low oil content, wastewater with high toxicity, high nitrogen content, and high COD (Chemical Oxygen Demand), etc. It has the advantages of good effect and low cost, but at the same time, it can also cause the water color to turn yellow.
3.In the dye industry, ferric chloride can also be used for engraving on printing and dyeing rollers, the production of circuit boards and fluorescent digital cylinders in the electronics industry, and as an oxidant in the dyeing of Indymium dyes, etc.
4. In the construction industry, FeCl3 can be used to prepare concrete to enhance its strength, corrosion resistance, and waterproofing. It can also be mixed with ferrous chloride, calcium chloride, aluminum chloride, aluminum sulfate, hydrochloric acid, etc., to form a waterproofing agent for concrete.
5. Inorganic industry: Ferric chloride can be used to produce other iron salts, inks, or catalysts (such as catalyzing the decomposition of H2O2);
6. Metallurgical industry: Anhydrous ferric chloride is used as a chlorination leaching agent for extracting gold and silver.
