Wastewater effluents contain synthetic dyes which may cause a potential hazard to human beings and to aquatic life. Dye bearing effluents are normally not easily amenable for conventional biological wastewater treatment due to their synthetic origin, complex aromatic molecular structures which make them difficult to biodegrade. Adsorption is considered to be a very effective separation technique and it is widely used in wastewater and water treatment. herbal seeds is a natural low cost agricultural solid waste available worldwide. This research showed That the amount of Methylene Blue dye adsorbed by seeds biomass increase with increase in initial dye concentration, contact time, temperature but was found to decrease with increase in solution temperature in the range of (20-40Cᵒ), pH and amount of adsorbent best pH was 6.92 and best weight was 1.3 g. The removal efficiency were in the range of (30%-80%).
