Enhanced adsorption of ceftriaxone antibiotics from water by activated carbon derived from agriculture products waste
The present work determines efficiency of domestic food waste like tea waste in removing pharmaceutical waste such as ceftriaxone (CEF) from synthetic wastewater. Carbonaceous material; Tea waste activated carbon (TAC) has been employed and it showed high removal capacity of 787.5 mg/g. TAC was characterized using; XPS, XRD, SEM, FT-IR, and BET as well as it approved that the adsorbent a has high surface area of .6 m2/g. Various experimental parameters are evaluated for the removal efficiency of the synthesized adsorbent under the present study. During the adsorption study through batch experiments, it approved that the adsorption isotherm was fitted to Langmuir, while kinetically fitted to pseudo-second-order; the adsorption process was chemisorption process as the adsorption energy was 23.7 kJ mol−1. From evaluation thermodynamic parameters the adsorption reaction was endothermic and spontaneous reaction. The different real samples spiked with CEF and studies the efficiency of TAC to remove it. On the other hand, investigated the regeneration efficiency of the TAC and exhibit high regeneration efficiency as it will be used after four cycles with good efficiency of about 84.2%.
期刊介绍：
Journal of Molecular Recognition (JMR) publishes original research papers and reviews describing substantial advances in our understanding of molecular recognition phenomena in life sciences, covering all aspects from biochemistry, molecular biology, medicine, and biophysics. The research may employ experimental, theoretical and/or computational approaches.
The focus of the journal is on recognition phenomena involving biomolecules and their biological / biochemical partners rather than on the recognition of metal ions or inorganic compounds. Molecular recognition involves non-covalent specific interactions between two or more biological molecules, molecular aggregates, cellular modules or organelles, as exemplified by receptor-ligand, antigen-antibody, nucleic acid-protein, sugar-lectin, to mention just a few of the possible interactions. The journal invites manuscripts that aim to achieve a complete description of molecular recognition mechanisms between well-characterized biomolecules in terms of structure, dynamics and biological activity. Such studies may help the future development of new drugs and vaccines, although the experimental testing of new drugs and vaccines falls outside the scope of the journal. Manuscripts that describe the application of standard approaches and techniques to design or model new molecular entities or to describe interactions between biomolecules, but do not provide new insights into molecular recognition processes will not be considered. Similarly, manuscripts involving biomolecules uncharacterized at the sequence level (e.g. calf thymus DNA) will not be considered.
