以铁粉、活性炭、氧化铜为原料,膨润土为黏结剂,并加入少量添加剂,通过焙烧制得新型铁碳微电解材料,并用其处理水中Cr(Ⅵ)。结果表明,当铁碳质量比为2∶1,铁与氧化铜质量比为6∶1,膨润土质量分数为20%,碳酸铵质量分数为0.5%,焙烧温度为400 ℃,焙烧时间为1.0 h时,制备的铁碳微电解材料性能最佳,其对水中Cr(Ⅵ)的去除率可达到81.64%。在铁碳微电解材料中加入氧化铜能明显提高Cr(Ⅵ)的去除率。

A new type of iron-carbon micro-electrolysis material is prepared by the roasting method,with iron powder, activated carbon and copper oxide as raw materials,bentonite as binder and a small amount of additives. Then it is used to treat Cr(Ⅵ) in aqueous solution. The results show that when the mass ratio of iron to carbon is 2∶1,the mass ratio of iron to copper oxide is 6∶1,the mass fraction of bentonite is 20%,the mass fraction of ammonium carbonate is 0.5%,the roasting temperature is 400 ℃,and the roasting time is 1.0 h,the prepared iron-c...
