Abstract

The identification of a bride range of organicpollutants in real water samples, especially in brackish water orwastewater is still a major issue in chemical analysis. The paperpresents a comparison of different solid phase extraction SPEmethods for the preparation of brackish water samples beforethe chromatographic analysis. The SPE methods werededicated to the extraction of selected organic cosmeticingredients - butylated hydroxytoluene BHT, oxybenzone BP3,and octyl methoxycinnamate OMC. Six types of SPE cartridgeswith different bed types and weights were tested. The SPEmethods included the conditioning of the column bed withorganic solvents, loading of the pre-treated brackish watersamples, washing out the impurities, and the elution of theanalytes. The highest recovery of the tested cosmetic ingredients,which has reached the value of 100% for BP3 and OMC, andexceeded 99% for BHT, was noted for the cartridge with theC18 (octadecyl) bed.
