This study reports adsorption of Methylene Blue (MB) and Basic Fuchsin (BF) on green reduced graphene oxide. Using modified Hummer’s method, Graphene Oxide (GO) was synthesised and reduced using Tamaridus Indica. The synthesised GO and RGO were characterized using XRD, UV–vis spectroscopy, TEM, XPS, FT-IR and BET analysis. Through XRD result, the reduction in a peak corresponding to (001) plane and appearance of new peak at (002) plane confirmed the reduction process. TEM results displayed a hexagonal SAED and lamellar structure in RGO with a d-spacing of 0.346 nm in the (002) plane. Effect of variables such as pH, initial dye concentration, dosage, temperature, sonication time, ultrasonic power and frequency were studied and optimum conditions for the removal of MB and BF were found. From the Langmuir isotherm model, the maximum adsorption capacity was noticed to be 238 …
