This invention describes a process for preparing high-purity nanoscale polyalumina sols. This invention uses active aluminum hydroxide and industrial hydrochloric acid as raw materials, and adopts a two-stage reverse stripping process to produce a solution of polyaluminum chloride with an alkalinity higher than 50%, which is then increased to 70% or higher using high-purity calcium aluminate as the alkalizer. The process ensures complete stripping of the aluminum hydroxide raw material at normal atmosphere and a low temperature, thus obtaining a high-purity product. In addition, in the produced polyaluminum chloride sols the total content of nanoscale Al13 and Al30 having Keggin structure is higher than 70%, the alkalinity is 70-85% and the aluminum concentration is 10-19% (measured as Al2O3).
