The ever-increasing demand for determining pesticides at low concentration levels in different food matrices requires a preliminary step of pre-concentration which is considered a crucial stage. Recently, the parameter of "greenness" during sample pr

Ozonation of surface waters that contain bromide result in the formation of bromate which has been identified as a potential carcinogen. Regulation of bromate at the preferred concentration of less than 5 μg/1 is being delayed due to lack of a valid
