Abstract
An analytical method for the simultaneous determination of acidic and neutral pharmaceutical active compound (PhACs) residues in wastewater has been developed based on the combination of high-performance liquid chromatography (HPLC) and photochemically induced fluorimetry. The photoderivatization conditions for each particular PhAC have been assessed. Off-line optimization of the HPLC separation for both neutral and acidic compounds has been utilised and evaluated. Detection limits in the low ng/ml range have been achieved without sample pretreatment. By applying the developed analytical method combined with solid-phase extraction to real wastewater samples an enrichment factor of approximately two orders of magnitude can be obtained.
