Abstract

The adsorption and reduction characteristics of chromium(VI) by oak sawdust were studied. The optimum adsorption condition is obtained from the measurement of the distribution coefficient(<TEX>$K_d$</TEX>) and adsorption capacity of Cr(VI) on the sawdust by changing pH of the solution. As a result, it was found that pH 2.0 was optimum because <TEX>$K_d$</TEX> of Cr(VI) was maximum and reducing quantity was minimum. By the use of these characteristics of the oak sawdust, the removing of Cr(VI) in industrial waste water was examined.
