  • What is poly aluminum-ferric chloride (PAFC)?
  • Author to whom correspondence should be addressed. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.
  • Is polyaluminum ferric chloride an inorganic coagulant?
  • 1. Introduction Polyaluminum ferric chloride (PAFC) is an efficient inorganic polymeric coagulant [1], [2]. Many studies [3], [4], [5] have demonstrated that inorganic polymeric coagulants were more effective than conventional inorganic coagulating salts in coagulation due to their resistances to the influence of wastewater initial pH.
  • How is PAFC prepared?
  • PAFC is prepared by microwave synthesis with a shortened time of 5 min and the conditions of preparation are optimized. Its performance is better than that of the commonly used polymeric aluminum chloride (PAC) and polymeric iron chloride (PAF).
  • Does pH affect the performance of polyaluminum chloride (PAC)?
  • The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
