Abstract
Nanoparticles are novel material because of their small size properties which is differ from its bulk material.This work aimed to study cobalt nanoparticles (Co-NPs) preparation using five different sol gel methods in order to evaluate the effect of synthesis variables that can influence the nanoparticles size distribution and particle shape. The synthesised nanoparticles were characterised by FTIR, SEM-EDX, and XRD. Out of these method five is more suitable and gives more accurate and appropriate results. The investigation process is carried out an adsorption study of all five NPs by different parameters such as effect of concentration of adsorbent, effect of concentration of dye, affect of pH, effect of contact time etc. were studied the adsorption capacity and adsorption behaviour of nanoparticals under various conditions. The experimental isotherm data has been studied. The kinetic study of the adsorption obeys Pseudo-first order model. The thermodynamic parameters namely Gibbs free energy, enthalpy, and entropy have revealed that the adsorption of methyl orange on the nanoparticlas is feasible, spontaneous and exothermic
