26.各種石炭に対するクロム酸イオンの吸着挙動

抄録

The surface structure of the various coals were studied from viewpoint of the adsorption behavior of chromic acid (VI) ion in the aqueous solution. It was found that the diffusion to inside of the coal particles varied in the various coals for the sorption process of the chromic acid ion. Furthermore, it was proposed that hydroxyl groups on the coal particle surface existed in following two different states in a difference of coal, (a) it was individual state and (b) the state which formed complex with the basic compounds.
