纳米TiO_2去除水中铜离子

The Study of Removing Copperions from Water by Using Nano TiO_2

对纳米TiO2光催化还原Cu2+的工艺过程进行了系统的研究。结果表明,纳米TiO2的最佳用量为1g/L,pH=3时为宜;含0.5mmol/L甲醇的体系对其光催化反应的促进作用最为有效,在此条件下,Cu2+的脱除率可达到83.28%。

Removing copperions from water by using nano TiO2 is studied in system. The results indicated optimum condition for photocatalysis reduction of Cu2+ is as following: the dosage of TiO2 is 1 g/L, pH=3, and 0.5 mmol/L methanol is added.
