Boron removal from wastewaters of geothermal plant was studied using N-glucamine type chelating resins so-called Diaion CRB 01, Diaion CRB 02, Purolite S 108. The batch-mode sorption studies was performed to obtain the optimum amount of resins for boron removal from geothermal wastewater. The boron on the resin was quantitatively eluted with 5% H2SO4. A column-mode study was performed using weak base ion exchange resin Diaion WA 30 for the separation of boron from H2SO4 solution. (C) 2004 Elsevier B.V. All rights reserved.
