Summary, etc. <span>Dyes are one the foremost hazardous pollutants that affects bio life including the flora and fauna and removing of those pollutants from contaminated environment are remarkable activities within the scientific community. In this respect, the current study is focused on preparation of physiochemical activated cereals based tella residue bio adsorbent for basic blue dye (MB) removal from aqueous environment. Different analytical methods have been utilized to assess the thermal stability, surface area, surface morphology, pore size, pore volume, surface functional group, and a few proximate analyses of the prepared bio adsorbents. The SEM and BET results of the adsorbents reveals physiochemical activation process assists for the formation of visible pores, cracks, irregular shape, and better surface area (51.32 m2/g for RTR and 565m2/g for ATR) respectively. The removal efficiencies of MB by RTR and ATR in an exceedingly batch experiment were 88.4s and 97.2 % at situation of pH (8); adsorbent dosage (0.8 for RTR and 0.6 for ATR), agitation speed (300 rpm), dye concentration (10 mg/L), temperature (298oK) and contact time (100 minute) respectively. The kinetics and equilibrium result of dye adsorption process well described by Pseudo 2nd order kinetic and Langmuir isotherm model respectively. The thermodynamic finding result shows the spontaneous and endothermic nature of the sorption process. The probable adsorption mechanism of MB dye on the prepared bio adsorbents surface may be assigned mainly through chemisorption. The results of this study show, the current adsorbents promise an alternate green rout for treatment dye contaminated wastewaters.</span>
