Environmental pollution caused by heavy metals that are deteriorating the environment and harm human health. This has become a serious problem due to the properties of the metals are dangerous and likely to bioaccumulate in the food chain. This research was the removal of cadmium and copper ions in solution on activated carbon coated with Mn3O4 with the objective to study the effect of the adsorption concentration and pH study. Affecting effective in removing heavy metals. The technique, atomic absorption spectra call bachelor's tome. Removal of cadmium and copper ions from solution onto activated carbon coated with the coating on Mn3O4 Mn3O4 by activated carbon (Mn3O4 / AC) prepared by the technique. supercritical And applied to eliminate the cadmium and copper ions from solution. Information about kinetic and isotherm of adsorption by Mn3O4 / AC compared to activated carbon (AC) and Mn3O4 pure, which found that the absorption of cadmium is 99.63, 96.97 and 99.99 percent for the temperature to 400 degrees Celsius. The amount of sorbent 1.6 percent weight by volume and at pH 4, respectively, for the absorption of copper is 96.60, 99.61 and 99.37 percent for temperatures of 400 ° C, the amount of sorbent 1.6 percent weight by volume and the PSP. The fourth respectively
