To optimize the process conditions, a series of experiments
was performed with different initial concentrations of H2O2
(in the range 0.30–0.55 mol L−1) at 11molL−1 Fe2+ concentration,
extending irradiation time from 3 to 6 h. The increase
of H2O2 initial concentration had an inhibition effect on COD
removal. The best result (90.5% COD removal) was obtained at
lowest peroxide concentration (0.30 mol L−1). As commented
before, this behavior could be explained because excessiveH2O2
reacts with hydroxyl radicals reducing treatment efficiency [3].
In complementary studies were verified that successive peroxide
additions promote better degradation compared to single addition
made in the beginning of the process (not shown). Therefore,
consecutive additions of hydrogen peroxide (30%) were realized
when the reagent concentration had been reduced in 80% of the
initial value.

将程序情况最佳化, 一系列的实验
是运行与不同的起始 H2 O2 的集中
(在范围 0.30-0.55个摩尔 L 中?1) 在 11 molL?1 Fe2+ 集中,
扩充来自 3 到 6 h 的发光时间。 增加
H2 O2 起始集中有禁止效果在雪上
移动。 那最好结果 (90.5% 雪移动) 是获得在
最低的 peroxide 集中 (0.30个摩尔 L?1)。 当做批评
以前, 这行为可能是解释因为 excessiveH 2 O2
和氢氧基急进份子反应减少治疗效率 [3] 。
在补充的研究是查证了那连续的 peroxide
附加促进较好的降格与独身者相较附加
制造在那开始程序.(不显示) 因此,
氢 peroxide(30%) 的连续的附加是了解
当试药集中有是减少在 80% 的
起始价值。
