摘要
对纳米TiO2去除水中铬离子进行了研究,并对反应条件对金属离子脱除率的影响进行了系统的讨论。研究结果表明,对于铬离子体系,pH值越小,其光催化效果越显著。此外,EDTA的添加有助于有效地去除铬离子。
In this work,the photocatalytic reduction of Cr6＋ in water by nano titania was studied.The results indicated that nano TiO2 adsorbs Cr6＋ strongly and the removal rate is increased with the decrease of the value of pH,as well as the addition of EDTA.
