Abstract

Abstract:

Corn straw based activated carbon was prepared from corn straw after formed and torrefied by H₃PO₄ activation and characterized by N₂ adsorption, elemental analysis and FT-IR. The results showed that the optimal conditions were the impregnated ratio of 4∶1, the activation temperature of 400 ℃ and the activation time of 100 min. Under these conditions, the yield of activated carbon was 47.78% and the activated carbon showed excellent adsorption capacity with the iodine adsorption value of 864 mg/g, the methylene blue adsorption of 210 mg/g and the caramel decolorization of 100%. The specific surface area and the total volume of activated carbon reached 1 105 m²/g and 0.745 cm³/g, the micropore volume was 0.287 cm³/g, the mesopore volume was 0.354 cm³/g. Meanwhile, the distribution of pore was concentrated within 5 nm, accounting for 73.56%, and the average pore diameter is 2.697 nm. The FT-IR results showed that the crosslinking reaction was occured between H₃PO₄ and corn straw during octivation and the activated carbon lost some functional groups of corn straw.

Key words: corn straw, activated carbon, phosphoric acid, preparation
