  • 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 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.
  • What is the optimum yield of medium polymeric (Al) content in PC species?
  • The optimum yield of medium polymeric (Al) content in PΑC species was predicted to 74.6 %, and the verification experiment result was 73.5 % at 0.5 M, 2.2, 75 °C and 273 min.
