Abstract
Adsorption characteristics of commercially available charcoal made of phyllostachys pubescens was quantitatively evaluated using the gas phase adsorption method. Micro-pore volume of the bamboo charcoal involved in adsorption is about 0.2mL/g, and has about 30-50% adsorption ability compared to a standard activated charcoal. It is a molecular sieve with a micro-pore diameter of 0.6-0.7nm. A comparison of absorption ratios shows that the micro-pore diameter depends on the temperature the bamboo charcoal is made at.
In conclusion, bamboo charcoal is a high-perfomance, functional material that is easy to produce (just by carbonizing mature bamboo). It also has excellent characteristics from the viewpoints of utilizing unused resource materials and energy consumption. The bamboo charcoal can be applied for the molecular level separation as a cheap absorbent.
