  • What is a preformed polyaluminum salt?
  • Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
  • Are polyaluminum chloride products FDA approved?
  • Polyaluminum chloride products used in the treatment of potable (drinking) water must be approved by the National Sanitation Foundation (NSF). Aluminum chlorohydrate for topical use as an antiperspirant is regulated by the FDA. (This is an excellent review of the literature on this chemistry.)
  • 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 polyaluminum chloride a Lewis acid catalyst?
  • Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst in inte
