Absztrakt (kivonat)
Antibiotics can act as a hidden poison when overused or misused that can contaminate water quality even at low concentrations. The situation has become a severe problem in the world because of the accumulation of certain beta lactam froups in the living organisms posing risks to human and ecological health. In this context, natural source-based carbon adsorbents materials have been proven to be capable adsorbents for the removal of such bulky beta lactam antibiotics. In reference their high surface area and porosity, low cost, and significant physical & chemical properties plays vital role in adsorptive removal. In the present study, low-cost carbon adsorbent was synthesized from the local available Saw Dust material collected from the local market at Pasaż Grunwaldzki, Wrocław, Poland. N2 adsorption-desorption isotherm, X-Ray Diffraction, and point of zero charge (pHZPC) characterization were used to confirm the successful synthesis of the material and changes in surface chemistry. The batch adsorption experiment revealed the higher efficiency of the prepared natural source-based carbon adsorbents as compared with the unprocessed saw dust, with maximum adsorption capacities of 22.2 mg/g for ampicillin and 9.16 mg/g for amoxicillin. Kinetic studies showed that the adsorption of both antibiotics followed a pseudo-second-order model indicating chemisorption, while the Langmuir isotherm provided a strong fit for the experimental data with correlation coefficients (R²) ˃ 0.90 implying adsorption occurred on monolayer surfaces, The adsorption on natural source-based carbon adsorbents was pH and temperature dependent, with lower adsorption observed at higher temperatures. Additionally, the adsorbent was easily regenerated using HNO3 solution. The results of present study suggest that such adsorbents prepared from natural based carbon materials can be potentially used for the removal of beta lactam antibiotics group especially in waste water treatment offering a sustainable solution.
