Abstract

As severe a threat to the environment as global warming is heavy metal contamination. Nano carbon fromLagenaria siceraria Stem fiber has been used to examine the removal of Fe(II) ions from aqueous solution. Itemploys batch adsorption methods. We looked into the effects of contact time, initial adsorbent concentration,dose, and solution pH. The equilibrium adsorption data were connected with the Langmuir, Freundlich,Dubinin-Radushkevich, and Redlich-Peterson isotherm models. The adsorption procedure wasadvantageous, according to the isotherm analyses of RL values. The evaluation of thermodynamic parametersH0, S0, and G0. The data show that the adsorption was endothermic in nature and spontaneous. Pseudosecond-order, Elovich model, and intra-particle diffusion models were used to investigate the kinetics ofadsorption. A pseudo-second-order adsorption reaction is suggested by kinetic investigations. This workdemonstrates that intra-particles were crucial to the mechanism governing the adsorption of Fe(II) ions.For the removal of Fe(II) ions from aqueous solution, the Activated Lagenaria siceraria Stem Nano Carbonhas a high adsorption capacity and adsorption rate.
