考察了芬顿试剂对田菁胶的氧化降解行为. 系统研究了H_2O_2和Fe~(2+)用量、温度和降解时间对田菁胶粘度的影响. 结果表明,H_2O_2和Fe~(2+)合适的体积比为2:1. 在较低的温度(25 ℃)和较短的时间(20 min)内芬顿试剂就能使田菁胶粘度下降90%以上. 另外,pH值的变化对其降解性能影响不大,显示了较好的降解效果.

The oxidative degradation of sesbania gum by Fenton reagent was studied. The effects of amounts of H_2O_2 and Fe~(2+), reaction time, temperature and pH value on the decreasing rate of the viscosity was investigated. The result shows that the appropriate dosage ratio of H_2O_2 to Fe~(2+) was 2∶ 1. The decreasing ratio of viscosity reached 90% at a low temperature within a short reaction time. In addition, the changing of pH value had little effect on the degradation performance of Fenton reagent, indicating the high oxidative degradability of sesbania gum by Fenton reagent.
