Solvent effect at ibuprofen adsorption using zinc oxide plate rod-like from gelatine

Abstract

The ubiquitous occurrence of several pharmaceuticals in sewage effluents has led to the considerable deterioration of some life forms and the quality of the receiving water bodies. Ibuprofen is a nonsteroid anti-inflammatory drug, represents a diverse class of drugs andthe most commonly used analgesics for the management of pain and/or inflammation associated with rheumatoid arthritis and osteoarthritis, muscle stiffness and pain, dental pain, migraine, and headache. The present work investigated the effect of different solvents on ibuprofen dissolution during the adsorption of Ibuprofen on to zinc oxide plate rod-like from its hexane, methanol, ethanol solutions, and water as co-solvents. The zinc oxide plate rod-like was synthesized using block copolymer and gelatine as a template and zinc sulphate as zinc precursor was then characterized by X-ray diffraction, scanning electron microscopy, and FTIR to analyse the structure and morphology. The impact of various solvents on the percentage removal (%) of Ibuprofen was determined by batch adsorption experiments. The data obtained were subjected to isotherm and kinetic analysis to describe the distribution of ibuprofen between the liquid and solid phases in the batch studies. The results obtained best fitted the Langmuir isotherm model with an adsorption capacity close to 110mg/g at room temperature with an initial concentration of 100 ppm. To sum up, for large-scale removal, ibuprofen treatment for aquatic, zinc oxide plate rod-like maybe an adsorbent in future.
