  • O-08　Determination of Acidic Groups in the Char Prepared from Wood and its Constituent Polymers by the Modified Boehm Method

抄録

<p>Acidic groups such as carboxylic and phenolic groups are associated with the physicochemical properties of biochar as a soil amendment. Generally, the Boehm method has been used for the measurement of acidic groups, but due to the use of titration, a large amount of biochar is required for the measurement. To study the evolution of these acidic groups in char in more detail, a smaller scale method is desirable. Also, alkali and alkaline earth metal cations in wood may interfere with accurate determination. In this paper, we propose a small-scale modified Boehm method using ash content measurement instead of titration. Influences of pyrolysis temperature (400-1000°C) on the development of carboxylic and phenolic groups were also studied for the carbonization of Japanese cedar (Cryptomeria japonica, Sugi) and its Klason lignin and cellulose (Avicel).</p>
