NOVEL KINETIC MODELLING AND OPTIMIZATION FOR ADSORPTION OF Zn2+ OVER GRAPHENE OXIDE | Journal of ..

Adsorptive studies' exponential expansion rarely results in actual physical translation of outcomes for decision-making processes. Type I, II, III, and IV pseudo second order kinetic models were used to investigate the kinetic adsorptive behaviour of Zn2+ on graphene oxide. All experimental runs were done in triplicates, with average values provided, and graphene oxide was successfully synthesised. For the first time, Microsoft Excel spreadsheet programming was utilised to model the experimental data and establish the best fit of the pseudo second order kinetic models on Zn2+ sorption research. With correlation coefficients of 0.999 and 1, the Type I pseudo second order and type I models got the greatest results. Model type I, II, III, as well as Type I, II, and III pseudo second order kinetic models, all had qe and H values that matched experimental data. The pseudo type IV and model type IV half times (t1/2) revealed a spontaneous interaction between the adsorbent and adsorbate, which was correlated with large H and qe values. As a result, we concluded that using our approach to apply the pseudo second order kinetic model to sorption data allows researchers to make well-informed conclusions.
