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.

Synthetic wastewater and other untreated water must be treated to allow for the drainage into rivers and re-using later. Adsorption focuses over the importance of means of extracting synthetic and inorganic contaminants from water. The research for products are available widely and that are inexpensive to use as adsorbents . Sewage sludge can be able to eliminate the dye of Bismarck brown R .the That Impact of different empiricism determinants such as contact time, temperature, solution pH, the weight of adsorbents, initial dye concentration and ionic strength were implementatio. The adsorption experiments involved all these equilibrium adsorption isotherms and kinetics. The implementation of Langmuir and Freundlich isotherms were examined at various temperatures, and the Langmuir isotherm showed suit better with experimental results. the thermodynamic determinants showed that the adsorption was an automatic practicability )ΔG was negative), the positive value of (ΔH) investigate endothermically and (ΔS) was positive value (random), The kineti information c show that the adsorption of Bismarck brown R with activated sewage sludge belongs to the pseudo-Second order kinetics.
