<P>PROBLEM TO BE SOLVED: To provide a method for recovering high purity boron from boron and phosphoric acid-containing drain discharged from various kinds of manufacturing processes and various kinds of treatment processes of plating, glass and medicines. <P>SOLUTION: In the method for recovering the high purity boron, water containing boron and phosphoric acid is passed through a boron selective adsorption resin and then a mineral acid solution is passed to remove boron adsorbed onto the boron selective adsorption resin. The recovery method for the high purity boron is characterized by passing the mineral acid solution of a mineral acid after passing an aqueous alkali solution. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
