Ferric chloride main purposes: mainly used for drinking water and wastewater purification purifying agent precipitating agent. Printing and dyeing industry oxidant used as a mordant when indigo dye. Trichloroethane and other production of organic synthesis catalyst. Silver chloride leaching agent coal washing and copper with ferric chloride, photographic and printing plate etching agent. Manufacturing raw materials such as iron phosphate, iron salts, pharmaceuticals, paints and inks. After its solution can penetrate buildings and building concrete strength, corrosion resistance and to prevent water seepage. Circuit boards for the electronics industry and the fluorescent tube production figures. Coagulant recovery glycerin soap when production waste. The most common use purposes than etching, especially printed circuit boards and stainless steel. However, because it is difficult to recycle sewage treatment ferric chloride, ferric chloride and environmental pollution, is more use of copper chloride. It is used in sewage treatment to remove heavy metals and phosphates in the water. In the laboratory, can be used to test the phenol Ferric chloride test, as follows: Prepare a 1% solution of ferric chloride ferric uses mixed with sodium hydroxide, until a small amount of FeO (OH) precipitate formed. The mixture is filtered. The sample was dissolved in water, methanol or ethanol. Added to the mixture, if significant color change, i.e., phenol or alcohol in the sample. In addition, we can use it to catalyze the decomposition of hydrogen peroxide into oxygen and water to make.
