Adsorptive Removal of Boron by DIAION™ CRB05: Characterization, Kinetics, Isotherm, and Optimization by Response Surface Methodology

A significant issue for the ecosystem is presence of boron in water resources, particularly produced water. Batch and dynamic experiments were used this research to extract form boric acid from aqueous solutions using selective resins, DIAION CRB05. DIAION™ CRB05 an adsorbent that effective extracting due its high binding capacity selectivity ions, it also regenerable, making cost-effective sustainable. Field Emission Scanning Electron Microscopy (FESEM), X-ray diffraction (XRD), FTIR analysis characterization. To increase adsorption find ideal values predictor variables such as pH, dose, time, concentration, Box–Behnken response surface method (RSM) was applied. The dosage reported be 2000 mg/L at pH 2 initial concentration 1115 with 255 min highest removal anticipated RSM. According outcomes research, material enhanced capability has superior performance several currently available adsorbents, which makes suitable use removing solutions. isotherm kinetic fitted linear methods. Temkin pseudo-first-order model found have good fits after comparison R2 0.998, 0.997, respectively. results study demonstrate effectiveness provide insight into optimal conditions process. Thus, resin chosen choice recovering solution because higher sorption percentage absorbed.
