  • 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 polyaluminum chloride (PAC)?
  • Sci.882 012014DOI 10.1088/1755-1315/882/1/012014 Polyaluminum chloride (PAC) is commonly used as a chemical in the water treatment industry, deodorant and paper-making. The PAC is a complex inorganic substance between hydroxyl and aluminum ions that gradually takes place chlorination with its general formula of Al x (OH) y Cl 3x-y.
  • How to prepare polyaluminum chloride (PAC G)?
  • In order to overcome the drawbacks, the fresh aluminum hydroxide gels were proposed to prepare the polyaluminum chloride (PAC G) in this study. The optimal preparation condition of PAC G was obtained by optimizing the preparation conditions including temperature, time and acid concentration.
  • Can aluminum hydroxide gels be used to prepare PAC?
  • An alternative preparation method of PAC was presented in this paper, using fresh aluminum hydroxide gels as the aluminum source. The procedure without the application of extreme conditions in terms of temperature and pressure had the benefit of saving energy.
