CHELATING ION EXCHANGE RESIN HAVING MAGNETIC PROPERTIES, PREPARATION THEREOF AND ADSORBING TREATMENT METHOD |
摘要 |
PURPOSE:To obtain a resin having sufficient resistance even in a strong acidic solution by forming the magnetic material of a chelating ion exchange resin from strontium ferrite or barium ferrite. CONSTITUTION:Phenols having a chelating functional group, phenols having no chelating functional group and aldehydes are subjected to polycondensation to obtain an precondensate. A magnetic material such as strontium ferrite or barium ferrite is dispersed in the precondensate and a dispersant is contained in the precondensate or an org. solvent to form a globular chelate resin having magnetic properties. The resin thus obtained has sufficient resistance even in a strong acidic solution and shows a fast treatment speed. |
