Abstract

In Indonesia, ammonia (NH3) is widely known as an essential commodity in industrial. But, in other side, ammonia is a dangerous and toxic polutant. There are several methods to turn ammonia waste into non-dangerous component, such as, biotreatment method, air stripping, breakpoint chlorination and ion exchanger. In contrary, those methods have some limitation and disadvantages, so, it’s a necessity to find another method which can give an effective and less-expensive result. Electrochemistry process is a method able to decrease ammonia concentration in waste lower than other methods. This research aims to learn thoroughly the ammonia concentration which is removed using electrochemistry process with Pt and stainless steel as the electrodes. The research will use time, initial concentration of ammonia solution and pH as the variables in electrochemistry process. At certain time operation, the higher solution’s pH, will cause the higher amount of ammonia with is able removed from the solution. This same condition is also prevail when the time operation is prolonged, which cause the decrease of NH3 concentration. In contrary, if the initial concentration of ammonia solution is higher, the removable ammonia concentration will be less, since the presence of intermediate compound hinders the ammonia adsorption.
