Water pollution is one of the major and widespread problems throughout the world affecting plants as well as human beings. Heavy metals adsorb readily onto the nonliving biomass of many aquaphytes. Biosorption of heavy metals from aqueous solutions is a technique for the treatment of industrial wastewater. Biosorption of Co (II) metal from the aqueous medium by modified Brassica Napus leaves (BNL) was examined for preliminary pH, initial metal absorption, and contact time. The most favorable sorption circumstances were studied for this metal discretely. The Chemical adaptation of biomass is carried out with an oxidizing agent (KMNO4). The kinetics and equilibrium models were applied to the data. The observed value was analyzed using simple linear regression. Studies showed that pretreatment of biomass dominated over all other clay and iron-supported composite hybrids. The Langmuir and Freundlich equilibrium adsorption models were investigated and observed to fit the data. The Freundlich model gave a better fit than the Langmuir model with an R2 value of 0.9999. The kinetic study revealed that adsorption was fast in the first 60 minutes and equilibrium was achieved after 120 minutes for heavy metal. Pseudosecond-order reaction model best describes the adsorption process.
