The Mechanism of Action of Polyferric Sulphate

Polyferric sulphate, as a highly effective inorganic polymer flocculant, occupies a significant position in the field of water treatment. Its mode of action encompasses multiple dimensions, achieving exceptional water purification results through synergistic effects. From the perspective of hydrolysis reactions, when polyferric sulphate comes into contact with water, the ferric ions (Fe³⁺) within the ferric sulphate molecules rapidly react with water molecules. This hydrolysis process facilitates the recombination of ferric ions with water molecules, forming hydroxide ions (OH⁻) and hydrated ferric ions. These hydrolysis products possess distinctive chemical reactivity, enabling them to chemically interact with various contaminants in water. For instance, they react with dissolved colloidal particles, altering their surface properties and thereby creating conditions conducive to subsequent purification. Oxidation represents another crucial mechanism by which polyferric sulphate purifies water. Leveraging its inherent oxidising properties, it engages in redox reactions with certain organic and inorganic substances present in water. During this process, originally soluble pollutants are oxidised and converted into insoluble precipitates. For instance, with regard to certain organic pollutants possessing reductive properties, polyferric sulphate can oxidise them, altering their structure from a soluble state to a precipitate state, thereby separating them from the water. Adsorption capacity is equally pivotal to the efficacy of polymeric ferric sulphate. Its distinctive porous structure and high surface activity endow it with formidable adsorption capabilities. Numerous adsorption sites function as ‘capture agents’, precisely adsorbing pollutants such as organic matter and heavy metal ions from water. Whether organic pigments in dye wastewater or heavy metal ions like lead and mercury in industrial effluent, polyferric sulphate effectively adsorbs and immobilises these contaminants, thereby removing them from the water body. Precipitation serves as the final stage in the water purification process achieved by polyferric sulphate. The interaction between hydrolysed and oxidised products forms stable, water-insoluble precipitates. These precipitates possess high density, enabling rapid settling to the water body’s bottom. During sedimentation, the precipitates collide with and agglomerate suspended solids in the water, akin to a snowball effect. This process encapsulates increasing quantities of pollutants, ultimately separating contaminants such as suspended solids, organic matter, and heavy metal ions from the water, thereby achieving significant purification.
