Use of thermal analysis for the study of the adsorption of pharmaceuticals from water
Original language description
The contamination of water with pharmaceuticals is one of the serious problems in themodern world. Their occurrence in surface- and groundwater brings a risk to the environment aswell as human health. Therefore many methods are studied in order of their removal. Adsorptionon activated carbon belongs to the most popular ones.Adsorption processes are conventionally studied by determining the equilibriumconcentration in the solution, usually with liquid chromatography or UV-visible spectrophotometry.Thermal analysis is usually applied for the investigation of the thermal regeneration of activatedcarbon. Nonetheless, these methods could be used for the basic research study of adsorbents withdifferent amounts of adsorbed contaminants.This contribution is aimed at using thermal analysis to study the adsorption of analgesicparacetamol (acetaminophen) on activated carbon. Two different samples of commercial activatedcarbon (one powder activated carbon and one granulated activated carbon) and different initialconcentrations of paracetamol were used. The granular activated carbon had to be homogenized byshort-time milling in a vibration mill. Equilibrium concentrations were determined with the aid ofUV-visible spectrophotometry and compared with thermogravimetric curves.
