Adsorptive Behavior of Medicinal Product Based Activated Carbon for Removal of Pharmaceutical Active Compounds in Aqueous Phase Redlich-Peterson Studies

摘要

Medicinal product based activated carbon was applied for the sorption of pharmaceutical active compounds in batch and aquatic systems.The MP-AC was characterized utilized X-Ray powder diffraction(XRD),Fourier Transform Infrared Spectroscopy(FTIR) and Scanning Electron Microscopy(SEM).The sorption process was found to be strongly dependent on the pH of solution which shows maximum sorption efficiency and sorption capacity at lower pH(pH=4) of 89.53% and qe = 29.35 mg.g~(-1),respectively.Moreover,the pHpzc also determined using drift method to evaluate the surface charge of the sorbent(pHpzc= 6.68).The sorption mechanism suitably described using a Redlich-Peterson isotherm model and confirmed by the value of chi-square test(X~2 = 0.01905).The results revealed that the sorption process is spontaneous and more effective at low temperatures.
