Abstract	This research was aimed to prepare and to characterize of CoOx@SnO2 which the concentrations of Co 1% and 2,5%. The compound of SnO2 was resulted by mixing SnCl4 with NH4OH solutions followed by calcinating the obtained solid. The samples were characterized by using FTIR, XRD, UV-Vis Spectroscopy, and SEM/EDX methods. Adsorption test was undertaken in the dark condition by mixing of various concentrations of CoOx@SnO2 onto metyl orange solution. The XRD analysis showed that the crystal size of CoOx@SnO2 with 1% and 2,5% of Co are 40.4971 nm and 34.7465 nm, respectively. The band gap energy of CoOx@SnO2 with 1% and 2,5% of Co are 1.78 and 1.83 eV. The SEM images presented that the particle size of CoOx@SnO2 are between 0.089 and 0.380 μm. The EDX analysis ilustrated that the amount of Co in all samples of CoOx@SnO2 is 0.1%. Adsorption capacity of the samples followed Langmuir isoterm pattern, i.e. 3.274394 and 3.877472 (x10-6) moles/gram for 1% and 2,5% Co, respectively.
