摘要

Abstract

High surface area activated carbons were produced by thermal activation of waste bamboo scaffolding with phosphoric acid.Single component equilibrium dye adsorption was conducted on the carbons produced and compared with a commercially available carbon.Two acid dyes with different molecular sizes

namely Acid Yellow 117(AY117) and Acid Blue 25(AB25)

were used to evaluate the adsorption capacity of the produced carbons.It was found that the dye with smaller molecular size

AB 25

was readily adsorbed onto the produced carbon

nearly three times higher than a commercially available carbon

while the larger size dye

AY117

showed little adsorption.The experimental data were analyzed using isotherm equations including Langmuir

Freundlich

Tempkin

Toth

Redlich-Peterson and Sips equations.The equilibrium data were then analyzed using five different non-linear error analysis methods.
