| Popis: |
The aim of this study was to develop a method for removing phosphate from an aqueous solution using iron (III) chloride-modified eggshells. The physicochemical properties of the modified biomass (FTIR, pHPZC) were examined. The sorption capacity of the modified sorbents was tested. The kinetic rate constant was determined using the general model and equals 1.82 10−10 min−1. The maximum sorption capacity of modified eggshells was determined using the Langmuir model (Qmax = 42.3 mg g−1). Kinetic experiments were also carried out in a fixed-bed column. To establish the adsorption parameters in the bed column, the Thomas, Yoon-Nelson, and MDR models were used to describe the experimental data. The maximum sorption capacity in the column was 58.4 mg g−1. Based on the result, modified eggshells could be used in the future as an effective sorbent for removing phosphate ions from aqueous solutions. |
