Adsorption capacity assessment for selected adsorbents in the removal of over the counter (OTC) analgesics from water

What is it about?

Pharmaceutical drugs can get into drinking water sources by different ways and subsequently affect not only the environment but also water quality. As the presence of drugs in water has recently become a hot topic, certain water management processes have already been developed for their removal from water, including adsorption on charcoal. In the context of specific research at the Department of Municipal Water Management, Faculty of Civil Engineering, BUT in Brno, laboratory measurements were implemented to determine the adsorption capacity of selected sorbents, especially the charcoal brands Filtrasorb F100 and F400 as well as Bayoxide E33 and GEH. The removed pharmaceutical group was represented by non-steroidal anti-inflammatory drugs including four types, namely ibuprofen, diclofenac, naproxen and paracetamol. The laboratory removal resulted in a comparison of these sorbents in terms of their adsorption capacity in the removal of the selected drugs from water.
