Sažetak
In last decades quantities of used and manufactured human and veterinary pharmaceuticals are increasing. After consumption, because of their physical-chemical properties, they end up in the nature. Consequently many of them pass through all of the natural filters and also wastewater treatment plants, and reach surface and ground waters. Those pharmaceuticals could cause adverse effects in ecosystems and can lead to pollution of sources for drinking water. Today, scientists all around world are trying to find the solution for removing of pharmaceuticals from wastewaters. Some using methods are physical separation (reverse osmosis/nanofiltration), biological treatment (membrane bioreactors), advanced oxidation processes (Fenton, photo-Fenton, ozonation, etc.), and sorption (activated carbon, industrial by-products, agricultural waste, etc.) [1, 2]. In order to reduce cost, less expensive materials as a sorbent, like different sludges, waste slurry, fly ash, blast furnace slag, anode dust, red mud were investigated [1- 4]. In this work, sorption of two different pharmaceuticals from wastewater, dexamethasone and ciprofloxacin separately, on waste sludge generated from pickling of steel pipes before galvanization process were studied. In order to follow the sorption of pharmaceuticals on sludge UV/VIS spectrometry was used. Sorption parameters of both pharmaceuticals on waste sludge were determined. All experiments were performed also with heat-treated sludge with the aim to demonstrate the influence of heat treatment on its sorption potential.
