참나무톱밥에 의한 6가크롬의 흡착과 환원특성이 연구되었다. 용액의 pH를 변화하면서 톱밥의 Cr(VI)에 대한 분포계수(<TEX>$K_d$</TEX>)와 흡착용량을 측정하여 최적조건을 발견하였다. 결과, pH 2.0이 최적조건이었다. 왜냐하면 이 pH에서 Cr(VI)의 <TEX>$K_d$</TEX>는 최대이고 Cr(III)로의 환원량은 최소이었기 때문이다. 이러한 참나무 톱밥의 특성을 이용하여 공장폐수중 Cr(VI)의 제거방법도 연구하였다.
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.
