Study on Adsorption Behavior of Glucose, Sucrose and Soluble Starch in Activated Carbon

Abstract

Respectively using glucose, sucrose and soluble starch as depositing agents, three series of deposited activated carbon samples were prepared by liquid-phase carbon deposition and were characterized by N2 adsorption-desorption measurements for studying the adsorption behavior of them in the pores of activated carbon. Results show that the depositing of glucose and sucrose can cause the decrease of micropore area, micropore volume, mesopore area and mesopore volume, but the depositing of soluble starch can not. It is concluded that glucose and sucrose could be deposited into various-sized pores of activated carbon, and soluble starch could not.
