摘要
以天然褐铁矿为光催化剂,以橙黄Ⅰ为目标降解物,借助氙灯光源模拟太阳光,考察降解体系初始p H、天然褐铁矿用量、光照强度、反应时间等对天然褐铁矿光催化降解橙黄Ⅰ的影响。正交实验结果表明,在天然褐铁矿光催化橙黄Ⅰ降解体系初始p H为2.0,天然褐铁矿用量为0.20 g,反应时间为2 h时,其对橙黄Ⅰ降解脱色率为98%,属于一级动力学反应。
Natural limonite and orangeⅠwas taken as photocatalyst and degradation target,and xenon lamp source was used to simulate sunlight to observe the effect of initial p H,natural limonite consumption,light intensity and reaction time on the photocatalytic degradation of natural limonite on orangeⅠ. The orthogonal experiment results showed that the degradation of orangeⅠdecolorization rate reached 98% when the initial p H of degradation system was 2. 0,the natural limonite consumption was 0. 20 g and the reaction time was 2 h. The photocatalytic degradation of orangeⅠcatalyzed by natural limonite obeyed a first order.
