Removal of Ciprofloxacin Hydrochloride from Aqueous Solution by Pomegranate Peel Grown in Alziedab Agricultural Scheme - River Nile State, Sudan

Abstract

Abstract:Removal of Ciprofloxacin (CIP) antibiotic from aqueous solution onto Activated carbon derived from pomegranate peel wastes collected from Alziedab Agricultural Scheme at River Nile state, Sudan as a novel precursorby chemical activation with Potassium Hydroxide (KOH), at specific condition of carbonization temperature at 500°C and 1 hour as a holding time and detonated as (AC(PPZS)KOH. The obtained material was submitted to measurements of active surface area, Fourier Transform Infrared Spectroscopy (FTIR) analysis and scanning electron microscope (SEM). Batch-adsorption studied had been carried out to examine the adsorption capacity of the AC(PPZS)KOH for the removal of Ciprofloxacin from aqueous solution. The effect of various process parameters like pH, initial antibiotic concentration, adsorbent dose, and contact time, on the efficiency of Ciprofloxacin removal was investigated. Maximum adsorption of Ciprofloxacin on AC(PPZS)KOH, (86.4 ± 5.7%) was observed at pH 8. The optimum adsorbent dose was determined as 0.05 g at 25°C. Initial Ciprofloxacin concentrations has important effect on AC(PPZS)KOH in the studied range (50-300 mg/L) where the removal percentage increases as the antibiotic concentration decrease. The adsorption equilibrium data was well explained by Freundlich isotherm. The results reveal the Langmuir model is not able to describe the experimental data properly, poor less of fitting on AC(PPZS)KOH. The Freundlich isotherm experimental data obtained showed (Correlation Coefficient, R 2 = 0.991) higher than Langmuir isotherm, R 2 = 0.919). The porous characteristics and adsorption efficiencies of prepared AC(PPZS)KOH were also investigated.

“…Many adsorbents have been reported for the adsorption of FQs [73][74][75][76][77][78][79][80]. As seen in Table 6, the adsorbent reported in this work had a good adsorption capacity and is advantageous in terms of easy separation.…”

Adsorptive removal of antibiotic pollutants from wastewater using biomass/biochar-based adsorbents

“…Another activated carbon derived from KOH-modified pomegranate peel wastes for ciprofloxacin removal from aqueous system has been reported. 86 The experimental findings revealed an optimum pH of 8, and recounted a high level of protonation on the adsorbent surface at lower pH that expedited electrostatic attraction between ciprofloxacin and the prepared activated carbon. Similarly, an optimum dose of 0.05 g was suggested from the experimental findings to yield the highest adsorption capacity, whereas there was a major decline in adsorption removal of ciprofloxacin at a higher adsorbent dose.…”

“…Similarly, an optimum dose of 0.05 g was suggested from the experimental findings to yield the highest adsorption capacity, whereas there was a major decline in adsorption removal of ciprofloxacin at a higher adsorbent dose. 86 Moreover, rapid adsorption removal of ciprofloxacin was attained within a contact period of 30 min, after which there was no significant increase in the adsorption removal of ciprofloxacin at a higher contact time. This outcome is consequent on the high initial concentration gradient occurring between the adsorbates and the number of unoccupied active sites on the adsorbents.…”

“…In addition, the adsorption isotherm for removing ciprofloxacin was best interpreted with the Freundlich model, compared to the Langmuir model which produced a maximum adsorption capacity of 2.353 mg g −1 . 86 …”

“…Antibiotics are indispensable in the treatment of infectious diseases of humans and animals. Of the various antibiotics currently in use, ciprofloxacin, a member of the fluoroquinoline family, and tetracycline, a broad spectrum antibiotic, are the most commonly used in the treatment of bacterial infections and as animal growth promoters 1,2 and both have been classified as high priority emerging organic pollutants by the World Health Organisation (WHO). 3,4 …”
