Abstract

One new technique of preparing high-efficiency flocculant was introduced by using raw materials as AlCl3·6H2O and FeCl3·6H2O.The influences of preparing conditions on the morphology and coagulation of polymeric aluminum-ferric chloride(PAFC) were investigated.The optimal experimental settings obtained by orthogonal experiment were n(Al)∶n(Fe) = 5∶5,baking temperature of 260°C,baking time of 25 min,maturation time of 4 h,and PAFC dosage for water treatment as 9 mg·L-1.The coagulation result of PAFC was fine under the above conditions.
