Plants are potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed toscreen potential plant species for removal of synthetic dye solution of triarylmethane dye Methylene Blue (MB) and diazo dye Congo Red (CR). Six plant species were screened for their phytoremediation ability for the removal of dyes present in synthetic wastewater. Six plants selected for screening areTrachyspermum ammi L. ( T. ammi ), Tagetes erecta L. ( T. erecta ), Hibiscus rosa-sinensis L. ( H. rosa- sinensis ), Chrysanthemum indicum L. ( C. indicum ), Bryophyllum fedtschenkoi ( B. fedtschenkoi ), Catharanthus roseus L. ( C. roseus ). The phytotreatment of dyes was done up to 40 hfortwo different concentrations of dyes 10 mg L ? 1 and 20 mg L ? 1 . Among these plants, the maximum decolouration was obtained from T. ammi plant followed by B. fedtschenkoi plant. Both of these plants showed active growth even after the phytoremediation process. T. ammi decolourised the MB dye 99% (10 mg L ? 1 ) and 86% (20 mg L ? 1 ) while the decolourisation of the CR dye solution was up to 95% (10 mg L ? 1 ) and 84% (20 mg L ? 1 ). T. ammi found to have maximum potential among screened plants for the removal of MB and CR dye from synthetic dye solution and can be used for decolouration of synthetic dye wastewater.
