A chemistry student needs to determine the Langmuir constant and maximum adsorption capacity of a metal oxide nanoparticle using the Langmuir adsorption isotherm equation from experimental data obtained at different concentrations of a given adsorbate in the water. Determine the Langmuir equation parameters and plot the experimental data and the Langmuir model using a graph. Finally, interpret the results in terms of the adsorption behavior of metal oxide nanoparticle towards the selected adsorbate.
