In this study, a simple, efficient and reliable HPLC method was developed for determination of ibuprofen and diclofenac belong to group of Painkiller and anti-inflammatory drugs in wastewater influents and effluents from WWTP. The method involves pre-concentration and clean-up by solid phase extraction (SPE). Final analysis of the selected pharmaceutical compounds was carried out by high-performance liquid chromatography (HPLC) on a reversed- phase C18 column using by gradient elution with methanol , acetonitrile and a 0.05 M phosphate-buffer (pH=4.5) at a flow-rate of 1 ml min-1 with diode array detector (DAD). The recoveries for all samples were more than 70%. The calibration curves obtained for studied drugs show reasonable linearity (R2 > 0.99) and the Limits of quantification were 0.05 ng ml-1 and 0.1 ng ml-1for ibuprofen and diclofenac, respectively. The described method was applied to the determination of the drugs in wastewater samples from WWTP in the south of Tehran.
