At present, there is a synthetic dye waste water is approximately 10-15% is different from industrial emissions into the natural water source which may cause problems further life in water ecosystems by Acid dye 2G Flavine (AF 2G) is a type of dye that is used in industrial, paper and leather goods.This type dyes are light, temperature stability, or oxidized and therefore degradation in nature, so the process is difficult to absorb (Adsorption) are used to get rid of this type of dye, which in this study were selected watduklum layered double hydroxides (LDHs) is an absorbent (Adsorbent), because there are high properties charge d LDHs.And higher exchange and ensity surface height When the temperature is 450° LDHs and C (CLDHs) will change the structure and there is more surface area allows for better absorption efficiency. Moreover, when dye adsorption in aqueous solution will keep the original structure that is returned but a layer of LDHs anion changes depending on the solution at adsorption to separate the absorption, reused easily repeated tasks. Therefore, there is a Magnetic iron oxide to remove (Fe3O4) that have properties that can be separated with a magnet. Used in conjunction with the CLDHs (Fe/CLDHs), which is prepared by precipitating and technical study of specific features of the Fe/SEM, XRD techniques CLDHs, TEM, FT-IR and VSM for audience education the ability to absorb the Acid 2G using Fe/CLDHs Flavine and studied the effect of pH, temperature, time, affect the absorption and efficiency of Fe/CLDHs. found that after 5 times the performance of adsorption efficiency 85% AF 2G also.
