  • What is polyaluminum chloride (PAC)?
  • Polyaluminum chloride (PAC) is a classic inorganic polymer material, which has the advantages of easy preparation, low cost, and high efficiency in the field of water treatment and other areas of environmental protection [ 1, 2 ].
  • 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.
  • Is PAC a polymer?
  • PAC is a polymer which has a long polymer chain, high positive electrical charge and large molecular weight [ 14 ]. PAC has three different aluminum species such as monomeric species (Al a) medium polymer species (Al b) and colloidal or gel species (Al c ), which are affected by basicity values during polymerization [ 15 ].
  • What is polyaluminum chloride used for?
  • The classic inorganic polymer flocculant—polyaluminum chloride (PAC)—was used as an environmentally friendly, efficient, and recyclable catalyst in the synthesis of Bis (indolyl)methanes (BIMs) compounds for the first time. The strategy of catalysis is to use PAC as a Lewis acid, which contains different structures of Al–O polynuclear cations.
