In this work will be to prepare nanocomposites based on polyvinyl alcohol and investigated. Laponit one of the famous and synthetic clays which are negatively charged. We tried to scratch the soil using the magnetic iron salts. Then nanocomposites based on poly (vinyl alcohol) will be produced using the magnetic clay. After Effects magnetic Laponit the structure and water absorption demonstrated in these materials as adsorbents cationic dye methylene blue was used. For the structure of nano-composites, techniques, FTIR, SEM, TEM and XRD were used. For the removal of cationic dye, effect, pH, ionic strength, temperature and initial concentration of dye methylene blue will be examined to optimize the conditions for the removal of dyes obtained by nanocomposites. Green experimental data using Langmuir and Freundlich adsorption models will be studied.
