The current study was done in order to find the efficiency of (spent tea leaves, orange peels, pomegranate peels) as adsorbents to remove industrial dyes; Congo red and methylene blue dyes. the results show that the three proposed adsorbents have a low to moderate ability to remove the dyes. The results show that depleted the tea leaves have a higher ability than orange peels and the pomegranate peels being the lowest in removing the methylene blue dye, while for the Congo red dye removal the orange peels were the highest followed by pomegranate peels and the lowest was the depleted tea leaves.
