Abstract: Bamboo-charcoal was pretreated with microwave or microwave with chemical reagent prior to its application. The methods and effects of pretreatment were studied. Results showed that specific surface area and adsorption capacity were elevated remarkably after pretreatment with the above mentioned methods, and the methylene blue adsorption values of bamboo-charcoal were increased over a range of 34%-92%. The methods were used in regeneration of bamboo-charcoal after adsorption of Pb²⁺, and the percentages of regeneration was up to 96%. The technology could be an effective means for activation of bamboo-charcoal.
