Abstract

Abstract:

The complex material， nanosized Cu₂O and attapulgite has been prepared by liquid-phase chemical sediment method. The material is used as catalyst for the decoloration of simulated dyeing wastewater under natural light. The techniques of XRD and SEM techniques prove that the material is a physical mixture. The effects of the complex material on the decoloring capacity， the dosage added to the wastewater， degradation time and the initial pH of the wastewater are investigated.

Key words: nanosized Cu₂O, attapulgite, simulated dyeing wastewater, decoloration

摘要：

用液相化学沉积法制备纳米Cu₂O/凹凸棒石黏土复合材料,并将其作为自然光催化剂进行模拟染料废水的脱色研究。X射线衍射(XRD)和扫描电子显微镜(SEM)技术证明该材料为纳米Cu₂O和凹凸棒石黏土物理混合物。研究了复合材料对模拟印染废水的脱色能力、复合材料的投加量、降解时间以及废水溶液的初始pH对脱色能力的影响。

关键词: 纳米Cu2O, 凹凸棒石黏土, 模拟染料废水, 脱色
