The Effect Of Boron Compounds The Pore Formation And Surface Area Of Activated Carbon Obtained From Pistachio Shell

It was reported the effect of boron compounds to the pore formation and surface area of activated carbon (AC) obtained from pistachio shell. Pistachio shells were activated by using two different methods and five different compound. These methods and compounds were washing/waiting with phosphoric(H₃PO₄) 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 900 ^oC, 45 minute under CO₂ washed H₂O atmosphere. Obtained results were compared with untreated shells, only carbonized. The shells have 1518 m²/g of BET surface area, 2.086cc/g DR pore volume and 5865,632 m²/g of DR micropore surface area for waiting in %10 ammonium biborate solution. The pore width as radius of obtained ACs and adsorption energy were 18,932 A^o and 6,867 kJ/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.
