It was reported the effect of boron compounds to the pore formation and surface area of active carbon (AC) obtained from the shell of pistachio. They were activated by using two different methods and five different compound. These methods and compounds were washing/waiting with hydrochloride (HCl) as acid solution or sodium hydroxide (NaOH) as base solution and waiting in boron compounds solution such as borax, boric acid and ammonium biborate. Shells were carbonized in high temperature furnace 900oC, 45 minute under CO2 washed H2O atmosphere. Obtained results were compared with untreated shells, only carbonized. The shells have 2.086cc/g DR pore volume, 1518m2/g of BET surface area, and 5865,632m2/g of micropore surface area for waiting in %10 ammonium biborate solution. The pore width as radius of obtained ACs and adsorption energy were 18,932Ao and 6,867kJ/mol for waiting in %10 ammonium biborate solution (ABB-PS). It was found that ABB-PS have higher micropore surface area, higher pore volume and lower adsorption energy. It was concluded that the pore structure and BET surface area of AC obtained from pistachio shell were developed by treating with boron compounds by compared of other compound in same conditions.
