Findings from Islamic Azad University Reveals New Findings on Antibiotics

May 30, 2014

By a News Reporter-Staff News Editor at Drug Week -- Investigators publish new report on Drugs and Therapies. According to news reporting originating in Tehran, Iran, by NewsRx journalists, research stated, "The adsorption characteristics of Cephalosporins antibiotics from aqueous solution were investigated using magnesium oxide (MgO) nanoparticles. Liquid phase adsorption experiments were conducted."

The news reporters obtained a quote from the research from Islamic Azad University, "Batch adsorption studies are carried out by observing the effect of experimental parameters, namely amount of adsorbents, pH, temperature and contact time. The drug removal data were fitted on Langmuir adsorption equations. The pseudo second-order kinetic model was indicated with the activation energy of 7.6682 and 5.3745 kJ/mol for Cephalexin and Cefixime, respectively. The values of the enthalpy (Delta H#) and entropy of activation (Delta S#) were 5.0851 kJ/mol and -286.67 J/mol K for Cephalexin; 3.1952 kJ/mol and -303.70J/mol K for Cefixime, respectively. The free energy of activation (AG#) at 30 C was 97.9 kJ/mol."

According to the news reporters, the research concluded: "Thermodynamic analysis showed negative values of AG indicating adsorption was favourable and spontaneous, negative values of AH indicating exothermic physical adsorption of Cephalosporins using MgO nanoparticles."
