Extraction of Drug Residuals from an Aqueous Solution Using Nanocellulose Adsorbent

In our study, we prepared three adsorbents to extract the emergent drug (ibuprofen) from an aqueous solution, such as cellulose nanocrystalline (CNC), magnetic cellulose nano-crystalline (MNC), and silver cellulose nanocrystalline (AgNC)). The cellulose was con-verted into CNC and then it was converted to MNCs and AgNCs. However, the NCs and AgNCs showed excellent extraction efficiency toward ibuprofen (IBP) compared to MNCs. Five variables were monitored and evaluated during the extraction process: time, pH, temperature, dosage, and IBP concentrations. The adsorption process followed Langmuir isotherm model and pseudo-second order. The negative ∆G° values indicate that the adsorption is favorable and spontaneous at different temperatures.
