| 摘 要： | 通过对3种含不同氰化物浓度的粘黄土泥样的测定，探索氰化物在粘土中的降解规律。结果表明：粘黄土对氰化物（CN^-）有较强的吸附与净化作用；CN^-浓度随时间的变化符合一级动力学模式；制备土样中CN^-的初始浓度高降解慢，初始浓度低降解快。

| Abstract: | The degradation law of cyanide in clay was explored through the measurement of its content if three different concentrations in elay mud samples. The results showed that clayish loess had fairly strong adsorption and purifica- tion on cyanide; and the concentration changes of cyanide accorded with the first-order kinetics model; and the higher initial concentration of cyanide in the prepared soil samples lead to slow degradation and the lower initial concentration lead to rapid degradation. |
