以氧化剂过硫酸铵（（NH4）2S2 O8）为活化添加剂，通过磷酸活化制备木质素基和木质素基活性炭。结果表明，（NH4）2S2O8用量小于10%时，氧化剂能提高活性炭得率，促进孔结构的形成。然而，在（NH4）2S2O8剂量高于10%时，产生过氧化条件，使得活性炭产率降低并且孔形成受到负面影响。氧化剂在磷酸活化过程中起两种作用：促进基体上磷酸酯的生成和碳的过氧化。
Lignin-based and wood-based activated carbons were prepared by phosphoric acid activation conducted using the oxidant ammonium persulfate ((NH4)2S2O8) as the activation additive. Results showed that at a (NH4)2S2O8dosage of less than 10%, the oxidant increased the activated carbon yield and promoted pore development. However, at a (NH4)2S2O8dosage of higher than 10%, an over-oxidation condition was created so that the activated carbon yield was reduced and pore development was negatively affected. It is suggested that oxidants play two roles during phosphoric activation, promotion of phosphate ester formation on the matrix and over-oxidation of carbon.
