通过测定好氧和厌氧条件下四氯化碳的转化速率和产物，研究了四氯化碳与黄铁矿的反应活性。在所有反应条件下，25 ℃下，1.2- 1.4m2/L黄铁矿存在下，12-36天内CCl 4转化率>90%。对四氯化碳浓度的零级依赖性支持了表面控制反应机理，其中反应速率取决于吸收的四氯化碳浓度
The reactivity of CCl 4 with pyrite was investigated by measuring the CCl 4 transformation rates and products under aerobic and anaerobic conditions. Under all reaction conditions, >90% of the CCl 4 was transformed within 12-36 days in the presence of 1.2-1.4 m 2 /L pyrite at 25 o C. A zero-order dependence on the CCl 4 concentration supports a surface-controlled reaction mechanism wherein the rate of reaction depends on the absorbed CCl 4 concentration
