Abstract: Green clover powdered leaves and their modified forms with lactic acid and tri sodium citrate have been used as low cost and eco-friendly adsorbents for the removal of iron from aqueous media. Samples were collected from different water supplies (surface, tap and ground water).The different factors affecting the adsorption procedure such as: adsorbent dose, stirring time and pH have been optimized for the sake of realizing maximum removal efficiency. The removal efficiency of the unmodified green clover was increased with the increase of the pH value until reaching its maximum uptake in the range 4-7. Both the sodium citrate and lactic acid modified green clover powders showed maximum uptake in the pH range 5-6. The removal process was slow in the first 35 min. then the uptake% was gradually increased till equilibrium after 50 min in case of unmodified green clover, the tri sodium citrate modified form showed equilibrium after 40 min. and the lactic acid modified one reached equilibrium after 50 min. Desorption processes proved the possibility of regeneration and reuse of the adsorbent
