  • 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.
  • 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 are the synthesis parameters of aluminum chloride hexahydrate?
  • The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
  • Does calcium aluminate react with aluminum chloride to increase basicity?
  • It indicated that the method of increasing the basicity in liquid PACl is viable, calcium aluminate reacts with aluminum chloride (zero base) to generate a high basicity PACl (Eq. (2)). The sample A exhibited the highest aluminum content (13.7%) and the highest basicity (92.9%).
