India ABSTRACT A series of blends consisting of Red mud RM varying from 1.5 to 3 g and Graphene oxide GO varying from 0 to 1.5 g to give a total of 3g were prepared. They are used as adsorbents in the treatment of waste water samples from few industries for effective removal of phosphates phenols heavy metals and dyes. The best blend compositions for removal of Phosphates Heavy metals amp Phenols Dyes were 2.5 0.5 2.75 0.25 2.1 0.9 respectively. The percentage removal of Phosphates amp Nickel was 100 while the removal of Zn varied from 58 to 68 for the refinery samples studied. The contact time required for 95 removal of phenols was just 4 hrs. In the studied dyes Congo red showed maximum adsorption of 10 mg g. Key words Red Mud Graphene Oxide Phosphate Heavy metals Phenol Dyes Cite this Article K. Gouru Naidu K. Venkata Krishna and K.
