“…Важливим недоліком ПАн є його порошкоподібний стан, що сприяє злипанню мікро-та наночастинок. Для запобігання цьому ефекту та посилення адсорбційних властивостей ПАн стосовно Cr(VI) синтезують композити поліаніліну з природними мінералими (мінеральними глинами), як-от бентоніту [28,29], глауконіту [30,31], ігнімбриту [32], каоліну [29], монтморилоніту [33], палегорськіту [34], сепіоліту [35], цеоліту [36−38] та ін. Відомо, що самі природні мінерали (ПМ) не мають високої адсорбційної ємності стосовно важких металів та хрому зокрема [28,39,40].…”

Industrial wastewater and other polluted water need to be treated to make it possible to discharge into rivers and reuse them. Adsorption takes the importance of ways to remove organic and inorganic pollutants in water. The search for materials that are locally available and cheap to use as adsorbent surfaces. The Iraqiporcellanite powder can be used to remove the dye of Rhodamine B in batch method. The effect of various experimental parameters such as contact time, temperature, solution pH, weight of adsorbent initial dye concentration, ionic strength were investigated. The adsorption studies included both equilibrium adsorption isotherms and kinetics. The applicability of Langmuir and Freundlich equations was investigated at different temperature, and the Freundlich isotherm exhibited the best fit with experimental data. The thermodynamic parameters indicated that the adsorption was a spontaneous process (ΔG was negative), the negative value of ΔH indicate endothermic and ΔS was positive value (random), the kinetic data well described by Pseudo-second order kinetic model with intra particle diffusion as one of the rate limitring steps.
