Modification of Kaolin and Its Adsorption Properties on Cr(Ⅵ)

  • 摘要: 采用煅烧、酸浸的方法对高岭土进行改性,通过对SEM、XRD、FT-IR、EDS、孔结构表征及高岭土对Cr(Ⅵ)的去除能力研究,确定高岭土的改性条件,考察改性高岭土对Cr(Ⅵ)的吸附特性. 结果表明:①高岭土的改性适宜条件为煅烧温度800℃、煅烧时间3h、c(HCl)为4mol/L;煅烧使高岭土的结构发生变化,活性增强;酸改使高岭土孔隙通畅,吸附性能增强. ②改性高岭土吸附Cr(Ⅵ)的优化条件为粒度0.15mm、用量10g/L、吸附温度30℃、吸附时间15min,该条件下ρ〔Cr(Ⅵ)〕为100mg/L时废水中Cr(Ⅵ)的去除率可达91.4%. ③高岭土对Cr(Ⅵ)的吸附过程符合准二级吸附动力学模型,相比于Freundlich方程,其吸附等温式更符合Langmuir方程.
