AB  - The aims of the research to develop nanotechnology with the use of bentonite as adsorbent cooper metal (Cu). Bentonite activation treatment performed. The parameters studied in this research is a variation of the mass of bentonite, contact time and adsorption capacity. Measurements were made using AAS. Activation of bentonite using a solution of HCl 1.6 M. In experiments conducted bentonite weight variation of 0.1; 0.3; and 0.5 gr with a contact time of 30,60,90 and 120 s. The results showed that the decreased absorption of active bentonite is 96.8 and 99,7% bentonit not activated Thus discovered a new phenomenon which is not activated bentonite is have a better ability to absorb copper compared to the activated bentonite.
