摘要
本文研究了纳米二氧化钛光催化降解水中染料类化合物,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,发现染料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 deradation of dyes in water by TiO_2 photocatalytic oxidotion was studied.The result showed that dyes wexe degraded by TiO_ 2nanometer powder entirely and converted into nontoxic inorganic ions such as NH+_ 4and NO-_3,and their concentrations during the degradation were also test.
