Abstract

ABSTRACT Column sorption–elution studies for boron removal were performed using N-glucamine-type chelating ion-exchange resins Diaion CRB 02 Purolite S 108. The breakthrough curves were obtained as a function of resin type and feed flow rate. Boron was effectively removed from the wastewater of Kizildere, Turkey, geothermal power plant by passing it through the resins Diaion CRB 02 and Purolite S 108 at a space velocity of 25 bed volumes per hour. The boron on the resins was quantitatively eluted with 0.25 M H2SO4 solution. The resin Diaion CRB 02 was used to study the recycle use of resin for boron removal from the wastewater of Kizildere geothermal power plant. The capacity of Diaion CRB 02 remained constant after three sorption–elution–washing–regeneration cycles.
