| In this study, in which the adsorption of 𝐶𝑑(𝐼𝐼) ions from aqueous solutions with the carbonization product obtained from the carbonization of paper mill waste sludge at different temperatures for two hours, it was observed that the adsorption efficiency increased with the increase of the carbonization temperature. The adsorption efficiency of 𝐶𝑑(𝐼𝐼) ions depends largely on the pH of the environment. By contacting the 100 𝑚𝑔/𝐿 solution of 𝐶𝑑(𝐼𝐼) with the carbonization product at 300, 400 𝑎𝑛𝑑 500 °𝐶 at a dose of 5 𝑔/𝐿 for 240 𝑚𝑖𝑛 at 𝑝𝐻 5.5, the current 𝐶𝑑(𝐼𝐼) ions were 45.3%, 52.4% and 61% removed. These values increased to 56%, 65.3% and 73.4% when the initial concentration of 𝐶𝑑(𝐼𝐼) ions was taken as 50 𝑚𝑔/𝐿. When the dose was applied as 20 g/L for the initial concentration of 100 𝑚𝑔/𝐿, all of the existing Cd (II) ions (except the carbonization product at 300 °C) were adsorbed. The results obtained for each carbonization product were applied to the Langmuir and Freundlich isotherms. The cadmium adsorption kinetics were defined with a second order model and the cadmium adsorption isotherm was determined to fit the Langmuir model better. The applicability of the results to the isotherm equations and the changes in the value of the isotherm constants depending on the carbonization temperature were examined. |
