摘要：

The preparation of depolymerised solutions from various zirconium salts in the cold and on boiling, the depolymerisation of polymerised zirconium solutions, and the dissolution of precipitated zirconium hydroxide by hydrochloric acid, are described. The concentrations of the zirconium solutions are between 10-4 and 10-1 M. The minimum permissible concentrations of various acids are shown by depolymerisation curves. Zirconium was determined by spectrophotometry with arsenazo III in 8 N hydrochloric acid, and the interferences by sulphate, perchlorate, phosphate, fluoride and nitrate are described. © 1969.
