Abstract: Effects of carbonizing temperature on characteristics and functions of bamboo charcoal were investigated with bamboo charcoal carbonized at different temperature. Characteristics of bamboo charcoal, i.e., refining degree, specific surface area, and pH value, differed with the carbonizing temperature. The pH of bamboo charcoal changes from acid to alkaline with rising carbonizing temperature. The specific surface area was maximum by bamboo charcoal carbonized at 800 deg C. The capacity of ammonia reduction were maximum at the carbonizing temperature of 200 deg C. The best carbonizing temperature for reduce residual chlorine and VOC was 800 deg C.
