Product Introduction
Product Introduction
Ferric chloride solution is usually prepared by slowly dissolving anhydrous ferric chloride (FeCl₃) in water (heat is released during dissolution, and stirring at controlled speed is required), presenting as a brownish-yellow to reddish-brown liquid. It is highly corrosive and can easily erode metals such as iron and steel. Therefore, it needs to be stored in corrosion-resistant containers made of plastic, glass, etc. It is commonly used in industry as a water treatment flocculant (to remove impurities from water), a metal etching agent (such as in printed circuit board processing), and can also be used in dye synthesis. When in use and storage, leakage and direct skin contact should be avoided.

Application
1. Water treatment flocculation: In the treatment of industrial wastewater and domestic sewage, ferric chloride solution can adsorb suspended impurities in water to form flocs, facilitating the sedimentation of impurities and enhancing the efficiency of water purification.
2. Metal etching: During the manufacturing of printed circuit boards, FeCl₃ solution can undergo chemical reactions with metals such as copper, etching the metal surface according to the designed pattern to form circuit textures.
3. Dye synthesis: In some dye production processes, ferric chloride solution can act as a catalyst or oxidant to promote chemical reactions and assist in the synthesis of the target dye components.
4. Concrete waterproofing: Add an appropriate amount of FeCl₃ solution to the concrete. It can react with the components in the concrete to form insoluble substances, block the internal pores, and enhance the waterproof performance of the concrete.
5. Wastewater decolorization: When treating colored wastewater from dyeing and printing, ferric chloride solution can adsorb pigment molecules in water and simultaneously remove the pigments along with the flocs through flocculation, achieving wastewater decolorization.
