Aim: Methodology: Results: Interpretation: Keywords: This study explores the possibility of treating basic dye, methyl orange using Scirpus grossus in a batch free flow surface system. The effect of operational parameters (pH, ORP, ABS, BOD, COD and TOC) for different dye -1 concentrations (0, 200, 400, 600, 800 and 1000 mg l ) were observed and determined during 42 days. The results of UV-Vis absorption, HPLC and GC-MS confirmed the degradation of methyl orange. The removal efficiency of

Moreover, the highest -1 -1 removal for BOD and COD in 400 mg l and TOC in 200 mg l methyl orange were 55, 52 and 42%, respectively. Four metabolites after the degradation of dye were identified as 4-tert-butylcyclohexanone, 1, 4-dimethylbenzen, N, N-dimethyl hydrazine, 1, 4, 7, 10, 13-pentaoxacyclopentadecane using GC/MS. Scirpus grossus is capable to phytoremediate dyes in wastewater.
