摘要：NOVELTY - The method of concentrating calcium chloride by using membrane involves adding 0.05% chelating agent to 2-30% calcium chloride stock solution, adjusting pH to 6-6.5, followed by using hydrophobic microporous membrane having pore size of 0.8 mu m. The membrane is hollow fiber membrane, flat membrane, tubular film or roll film, preferably hollow fiber membrane. USE - Concentrating calcium chloride solution by using membrane (claimed).
