This article utilizes still popular medicinal herbal plant Acorus calamus rhizome as a decisive substitute for exclusion of Basic Green 4 (BG 4), a cationic dye from its aqueous solutions by making use of batch investigational system. Further plausible mechanisms were achieved by correlating experimental values with the predicted kinetic models thus exploiting high significant rate statistics of the model preferred. Experimental biosorption data were modelled by Langmuir, Freundlich, Tempkin, Dubinin-Radushkevich (D-R) isotherm, Redlich-Peterson (R-P) isotherm, Harkins- Jura (H-J) isotherm and Generalised isotherms. The biosorption route followed the Langmuir isotherm model with high coefficients of correlation (R > 0.99).Thermodynamic parameters suggest that the biosorption process is spontaneous and endothermic in nature. Overall, this article summarizes the efficacy of herbal biosorbent for the elimination of BG 4
