“…This was also proved by the negative values of ΔH°at all temperatures because of releasing extra energy due to interaction of dye with adsorbent. [30,17] The negative values of entropy changes (ΔS°) indicate the decrease of randomness in binary system too. [37] 3.9.…”

“…[12] It is synthesized by heating wood or other carbon containing matter in absence of air, which increase the available surface area many folds. [13,14] Enormous studies have been made for the removal of dyes from single dye solution in order to control water pollution [15,16,17,18,19,20] but little work has been done on simultaneous adsorption of two or more dyes from binary or ternary mixture. [1,21,22,8,23,24,25,11] Study on simultaneous adsorption of dyes might be very helpful to know the interference of one dye with the other dye present in the textile wastewater and check the suitability of adsorbent to remove such dyes from real effluents.…”

Charcoal prepared from Kail Sawdust (waste obtained from carpenter shop) has been used as adsorbent for the simultaneous removal of red RB (RRB) and yellow M4G (YMG) dyes from water. The interactive effect of both dyes is found as antagonistic. The experiments are performed on optimized operating parameters, which are based on individual dye adsorption. Experimental results are tested for Langmuir, Freundlich, and Temkin adsorption isotherm models but the equilibrium data fitt well with Langmuir isotherm model. Adsorption kinetics fit well pseudo second order kinetic model. FTIR, SEM, and BET analysis are used to characterize the adsorbent. Adsorption process is spontaneous, feasible, and exothermic as proved by thermodynamic parameters. From the outcomes, it is presumed that removal of dyes by KSC (bioadsorbent) can be proved as successful and green innovation for the treatment of textile industrial wastewater.
