Ferric chloride is quite a strong Lewis acid, with a Lewis base, such as triphenylphosphine oxide, can be composed of a stable FeCl3 (OP-Ph3) 2 (Ph = phenyl). Ferric chloride in hydrochloric acid and chlorine can be composed FeCl4? Complex ions, phosphorus agent ferric chloride, which is yellow, which is the industry concentrated hydrochloric acid was yellow reasons, it can be extracted with ether. Oxalate ions and ferric chloride, to obtain a stable coordination compounds such as [Fe (C2O4) 3] 3 ?. Ferric chloride is the general strength of the oxidizer, oxidized copper chloride, copper chloride. Reducing agents such as diamide, efficient ferric chloride manufacturers, ferric chloride can become complex compound of iron. Ferric chloride is cheap and efficient flocculant urban water and industrial wastewater treatment has significant precipitation of heavy metals and sulfides, bleaching, deodorizing, degreasing, sterilization, removal, reduce the effluent COD and BOD and other effects. Compared with other wastewater treatment flocculants, ferric chloride bleaching agents, its main features are as follows: replace liquid or solid aluminum sulfate, PAC, PFS and other flocculants, reducing processing costs by more than 30%; good flocculation Hefei ferric chloride coagulant sedimentation rate higher than aluminum series (such as aluminum sulfate, aluminum chloride, etc.), and the formation of alum dense; produce less sludge, saving the cost of sludge treatment; adapt water wide pH range, from 4 to 12, the optimum pH range of 6 to 10. Metal etching dedicated ferric chloride, flourishing green (online consultation), Hefei ferric chloride provided by the Hubei Environmental Protection Engineering Co. Spirit.
