  • 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.
  • 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%).
  • How much alumina is in bauxite?
  • Bauxite with the particle size under 150 meshes, namely light frit, has 30–40% weight of alumina and 1–5% of ferric oxide. The properties of the bauxite can be seen in Table 1. Generally, the higher concentration of hydrochloric acid is used, the higher percentage of alumina dissolves out.
