الملخص EN

A new procedure for the simultaneous determination of Oxyfluorfen and Chlorpyrifos pesticides in environmental aqueous samples was developed.

It was based on solid-phase extraction (SPE) using spent coffee grounds (a residue from soluble coffee industry and / or coffee shops) as sorbents and high-performance liquid chromatography-ultraviolet detector for the enrichment and determination of the two pesticides at trace level.

Some parameters that influence the enrichment efficiency of spent coffee grounds towards those pesticides, such as eluent type and its volume, pH of the water sample, volume of the water sample, mass of the sorbent, and column regeneration were investigated and optimized in detail.

Under the optimal SPE conditions, the linear range, detection limit, and precision (R.

The proposed method was successfully applied to the analysis of tap water and stream water samples and satisfactory spiked recoveries were obtained in the range of 100.3–106.2 %.

The above results indicated that the developed method could be used for the routine analysis in environmental water samples.
