“…The pH and pH ZPC of nanocarbon sphere was below 7.0, could may be due to the presence of acidic functionalities. The bulk density is very small and the surface area of nanocarbon sphere is 700.7 m 2 /g, which is comparable with that of commercial variants (Table-1) [26]. Effect of pH on the adsorption of acid blue 113: In any adsorption system, the pH is considered as one of the dominant parameters which has control over the adsorption of dye ion onto to the given adsorbent.…”

Nanocarbon spheres were prepared from the stems of Alternanthera sessilis. Their characterization studies were performed and the application of nanocarbon spheres for the adsorption of acid blue 113 from the aqueous solution was studied. Effect of pH of effluent, effect of initial acid blue 113 concentration and the effect of solution temperature were analyzed. Pseudo-first order model, pseudo-second order model, Elovich model, Intra-particle diffusion model, Langmuir model, Freundlich model and thermodynamic parameters were used to evaluate the percentage and the amount of acid blue 113 dye removed. The kinetics follows multi-order and Langmuir type of isotherm. The ΔG, ΔH and ΔS parameters which relate to sorption energy were also evaluated. The outcome of the study indicates that nanocarbon sphere is a potential material for the sorption of acid blue 113 with good efficiency.
