Continuous adsorption work in the fixed bed column was carried out by using peanut grain leather as an adsorbent to remove methylene blue (MM) from the water solution. The effect of the initial MM concentration (20-60 mg/L), flow speed (5-10 mL/min) and the amount of adsorbent (1.5-2.5 g) on the adsorption properties was studied. The obtained data confirmed that breakthrough curves depend on the flow speed, the starting paint concentration and the amount of adsorbent. Thomas, Yoon-Nelson and Adams-Bohart kinetic models were applied to experimental data to predict breakthrough curves and to determine the characteristic parameters of the column, which is useful in the process design. Only the Adams-Bohart model was found suitable to predict the beginning of the dynamic process.
