In this study, when Cyperus alternifolius plants were exposed to atrazine) 20 mg L -1(, OPC-LD )20 mg L -1(, OPC-LD )50 mg L -1(, fluorine )3.5 mg L -1(, and 1-4 Dioxane )25 mg L -1(, in a mesocosm treatment floating bed system, the phytoremediation efficiencies were 91.28 ± 6.35%, 82.33 ± 2.51 %, 75.67 ± 3.05%, 62.28 ± 5.77% and 42.29 ± 2.27 % respectively. When Amaranthus retroflexus plants were exposed to metformin )20 and 50 mg L-1( and OCP-LD )20 and 50 mg L-1(, 63 ± 5.24 %, 58.4 ± 2.11%, 38 ± 1.73 %, and 29 ± 01 % of the pollutants were removed. In the case of Closia cristata, the most efficiency belonged to metformin with a concentration of 50 mg L-1 . The results showed that in water containing NaCl in a range of 1000 to 2000 mg L-1 , Bambusa vulgaris with an efficiency of about 32.62 ± 4.65 % is a good candidate for phytodesalination. Consequently, C. alternifolius, a fast-growing plant with a good ecological stability in polluted water, can absorb pollutants and remains healthy after the treatment period. It is a good candidate for phytoremediation in vegetated floating beds.
