- Abstract
- To verify Loess additive as a reduction material in leachat of hexavalent chromium, concentrations of hexavalent chromium was determined by spectrophotometry. After the analysis The resultant concentration of acid soluble hexavalent chromium was satisfied with domestic and international standards, and the concentration of leached hexavalent chromium was dependent on the pH in solvent. 중금속 침출 저감제로서의 Loess계 첨가제의 적합성을 판단하기 위해 분광광도법을 이용하여 6가크롬이온 침출 농도를 측정하였다. 그 결과 Loess계 첨가제의 산가용성 농도의 경우 국내외 기준에 적합하였으며, 침출되는 6가크롬이온 농도는 용매의 pH 값에 영향을 받는 것을 알 수 있었다.
