摘要：

本文考察了芬顿试剂对田菁胶的氧化降解行为。系统研究了H2O2和Fe2+用量、温度和降解时间对田菁胶粘度下降百分率的影响，并简单讨论了芬顿试剂对田菁胶的氧化降解机理。结果表明，H2O2和Fe2+的合适用量之比为2︰1。另外，只需较低的温度(25 ℃)和较短的时间(20 min)，芬顿试剂就能使田菁胶粘度下降90%以上，显示了较好的降解效果。

Abstract:

The oxidative degradation of sesbania gum by Fenton reagent was studied in the article. The effect of amount of H2O2 and Fe2+, reaction time and temperature on decreasing ratio of viscosity was investigated. The result showed that the appropriate dosage ratio of H2O2 to Fe2+ was 2︰1. In addition, the decreasing ratio of viscosity reached 90% with low temperature and short reaction time, which showed the high oxidative degradability of Fenton reagent for sesbania gum.

Key words: Fenton reagen, sesbania gum, oxidative degradation, viscidity
