In this study, Pseudomonas putida biomass was used for the removal of ceftriaxone from aqueous solutions. The optimal conditions were determined, and the Freundlich adsorption isotherm model was found to fit the experimental data better.
In this study, Pseudomonas putida biomass was used to remove ceftriaxone from aqueous solutions. Biosorption was studied by living bacteria to achieve maximum biosorption. In order to investigate the shape, the biomass structure was analysed by SEM and FT-IR analyses. The effect of important parameters such as pH, contact time, adsorbent amount, and initial concentration of ceftriaxone solution, temperature, and the effect of ionic intensity on biosorption were studied. This study is an experimental study 250 ml Erlenmeyer was used as a batch reactor for the experiment. With increasing initial concentration, the removal efficiency increased. The best results were obtained at optimum pH = 7, adsorbent dose of 0.1 g, and initial ceftriaxone concentration of 50 mg/l after contact time of 120 minutes at the temperature of 37 degrees C and more than 50% of ceftriaxone was removed. Various isotherms including Langmuir and Freundlich were used to analyse equilibrium data at 37 degrees C. The maximum adsorption capacity of this adsorbent was 109.5 mg/g. The results showed that the Freundlich isotherm is more consistent with the experimental data. Data fitting in the Freundlich adsorption isotherm model indicates non-uniformity of the absorbent surface.
