Herein, MIL101 (Fe)phosphotungstic acid (PA) composites were synthesized and characterized. Materials Institute Lavoisier (MIL101 (Fe)) composites as metalorganic frameworks (MOFs) with 0, 0.347, 0.694 and 1.042 mmol of PA were synthesized and denoted as MIL, MP1, MP2, and MP3, respectively. The synthesized MOFs were used to remove organic contaminants from binary systems (BB:Basic Blue 41 and MB:Methylene Blue). The synthesized materials were characterized in detail. Pollutant removal obeyed the Langmuir isotherm and pseudosecondorder kinetic. The free energy of adsorption for MP2 at 298, 308, 318 and 328 K was 15.24,15.93, 16.63 and 17.32 kJmol for BB and 15.04, 15.02, 15.01 and 14.99 kJmol for MB, respectively. Adsorption by the synthesized materials was spontaneous and endothermic process. The multicomponent dye removal data indicated that the synthesized MIL101 (Fe)phosphotungstic acid (PA) composites could be used as efficient adsorbents for treating colored wastewater. In addition, the synthesized MOFs were recyclable and regenerable adsorbents.
