    摘要: Significant amounts of soluble fluoride, known to create problems in processes requiring high quality grade calcium chloride, are removed from calcium chloride solution using hydroxyapatite as a removal mechanism. Under acidic conditions, calcium chloride solution is purified to about less than 10 ppm fluoride, significantly, to less than 1 ppm fluoride. At least 0.1 weight percent hydroxyapatite and concentrated hydrochloric acid are added to calcium chloride solution and slurried to remove fluoride and create a highly purified calcium chloride solution, substantially free of fluoride.

    摘要: A purification method of a metal salt which comprises bringing a metal salt formed by melting an alkali metal salt, an alkaline earth metal salt or a mixture thereof into contact with titanium or the like, thereby adsorbing impurities in the metal salt, a deoxidization method by melting metallic calcium into a molten product of the metal salt purified by the purification method and bringing the same into contact with a titanium material, and a production method of the titanium material which comprises conducting molten salt electrolysis by using the molten product of the purified metal salt for an electrolytic bath. Using the purification or production method the molten metal salt can be purified simply and conveniently at good efficiency. Then, use of the purified metal salt can minimize contamination caused by the metal impurities in the molten salt and the titanium material of high quality can be produced.

    摘要: In a brine treatment method of removing sulfate ions from sulfate-ion contained brine, sulfate-ion contained brine is brought into dispersive contact with granular ion exchange resin carrying zirconium hydrous oxide thereon in a fluid state under an acidic condition to thereby cause the sulfate ions to be adsorbed by the ion exchange resin and removed from the brine, then the granular ion exchange resin is washed with aqueous solution whose pH value is equal to or lower than a pH value in the adsorbing step, thereby removing chloride ions from the granular ion exchange resin, then in a fluid state, the granular ion exchange resin adsorbing the sulfate ions is brought into dispersive contact with aqueous solution of pH value higher than the pH value in the adsorbing step, thereby desorbing the adsorbed sulfate ions from the granular ion exchange resin, and then the granular ion exchange resin is washed with water.
