PURPOSE:To obtain a phenolic chelate resin having selective adsorbing capacity to boron, by introducing amino phlyalcahols into a phenol nucleus as a chelate forming group. CONSTITUTION:In a phenolic chelate resin, amino polyalcohols having a group shown by formula (wherein R1 is H or 1-5c alkyl, n is aninteger of 1-6) is introduced into a phenol nucleus as a chelate forming group. Thus a phenolic chelate resin in obtained by a simple method, which has an excellent effect of adsorbing special metals, especially, boron in an aqueous solution and permits repeated use by simply regenerating with an acid. |
