- چکیده:
- چکیده انگلیسی: The present work aims to evaluate two native plants including, Hammada scoparia (H. scoparia) and Halocnemum Strobilaceum (H. Strobilaceum), which grow in Benghazi-Libya for soil phytoremediation purpose. Plants and soil samples were collected and analyzed for Cu, Zn, Fe and Cr concentrations at different sites in the north coastal region of Benghazi. Performance of Hammada scoparia and Halocnemum Strobilaceum was evaluated by calculating biological absorption coefficient (BAC), bioconcentration factor (BCF), and translocation factor (TF). Both plants were found to be a moderate extractor. The tendency of the plants toward phytoextraction process and phytostabiliztion process was studied. Both plants tend to phytoextraction process except Halocnemum Strobilaceum tends strongly to phytostabiliztion process in case of Cu and Fe.

- چکیده:
- چکیده انگلیسی: Propylene oxide-ethylene oxide block polymer (PO-EO) is a surfactant with low cloud point. It has been used for separation of Cu2+, Fe3+, Mn2+, Cd2+ and Cr3+ ions in aqueous media. The effect of different factors on recovery percent, like pH, temperature, amount of chelating agent, and amount of surfactant have been studied. A very good separation of metal ions could be achieved at different pH values with good effeciency of separation under the optimum conditions. The analyses of metal ions were carried out using flame atomic absorption spectrometer with duterium lamp background correction and calibration curve method curve method.
