Acid blue 9 is an organic dye commonly used to dye cotton, wool, and silk. The use of this color has harmful and destructive effects on the human body. In this study, an attempt has been made to make a hybrid of chromium-based metal organic framework (MIL-101) and triazine based covalent organic framework. Due to the importance of completely eliminating this color and paying attention to economic aspects and reducing costs as well, In this proje ct an attempt has been made to make a hybrid of chromium-based metal organic framework (MIL-101) and triazine based covalent organic framework and to use it to remove this organic dye. To do this, at first nitro group was added to MIL-101 and then MIL-101-NH2 was synthetized by reviving it. To grow the covalent organic framewok, Cyanuric chloride was added as the binder and then melamine was added and grown the covalent organic framework. Synthesized hybrid has identified by FT-IR, X-ray diffraction, elemental analysis, TGA, BET and FE-SEM methods. To determine the efficiency of this hybrid, the adsorption process was investigated by UV-Vis spectrophotometer. To determine the efficiency of this hybrid in removal of acid blue 9, the adsorption process was investigated under the optimal conditions. Optimal conditions for the uptake of acid blue 9 by this hybrid were measured at pH= 2, color concentration of 150 ppm, adsorption value of 0.01 g, temperature of 35 °C in 90 min. The amount of substance absorbed was 256 mg/g. Compatibility of experimental results with Langmuir adsorption isotherm and quasi-secondary kinetic model shows that the adsorption of the desired dye is controlled by chemical adsorption
