摘要
本文研究了纳米二氧化钛光催化降解水中氨基甲酸酯类化合物,实验结果表明纳米二氧化钛能将其有效地降解成无毒的无机产物;同时监测了降解过程中的氮类无机产物的含量,发现氨基甲酸酯类化合物在光催化过程中先被氧化分解成NH4+;再进一步被氧化成NO3-。
The photocatalytic degradation of N-methylcarbamate with TiO2 nanometer powder was studied. It was showed that nano-TiO2 can degrade N-methylcarbamate into non-toxic inorganics effectively. Meanwhile, it was discovered through monitoring the content of nitrogen etc. inorganics in the course of degradation that N-methylcarbamate compound was first decomposed into NH4^＋ in the course ofphotocatalysis, then was further oxidated into NO3^-.
