Absztrakt:
Fluoride leaching from phosphogypsum waste is an environmental problem that can affect living things. This study started with phosphogypsum leaching, separation into some fractions based on the mineral each fractions rich in (according to XRD patterns) and analysed each of fractions fluoride contents using ISE. All of the analysed fluoride content would be higher than the standards chosen for this study (EU Decision 2003/33/CE and Tunisian NT 106-002 1989).
