WebThe elongation of primary α-Fe2O3 particles produced in the presence of SDS was noticed. This effect can be assigned to the preferential adsorption of dodecyl sulphate groups on nuclei and crystallites of FeOOH and α-Fe2O3 phase during the forced hydrolysis of FeCl3 solutions. In the largest application iron(III) chloride is used in sewage treatment and drinking water production as a coagulant and flocculant. In this application, an aqueous solution of FeCl3 is treated with base to form a floc of iron(III) hydroxide (Fe(OH)3), also formulated as FeO(OH) (ferrihydrite). This floc facilitates the separation of suspended materials, clarifying the water. Iron(III) chloride is also used to remove soluble phosphate from wastewater. Iron(III) phosphate is i…
