  • What is high-purity poly-aluminum chloride (PACL)?
  • Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
  • Is poly aluminum chloride a macro molecule?
  • ... Poly aluminum chloride (PAC) is a mineral macro molecule in terms of composition and its monomers are dual-core complexes of aluminum (Wang et al. 2015).
  • What is the molecular formula of poly-aluminum chloride?
  • One of the major pre-polymerized coagulants, poly-aluminum chloride (PACl) is used broadly for water and wastewater treatment. PACl contains different amounts of hydroxyl, and the molecular formula of PACl is [Al m (OH) n (H 2 O) x]·Cl 3m−n (n ≤ 3 m).
  • What is the basicity of high-purity PACL?
  • The basicity of high-purity PACl can be maintained at about 92% after the adjustment by calcium aluminate (Table 3), it has exceeded the national and international standards of PACl.
