Mechanism of Humic Acid Influence on the Adsorption of Phosphate on Goethite

  • 摘要: 通过添加HA(Humic acid,腐殖酸),研究不同环境条件下HA对针铁矿吸附磷的影响. 结果显示,加入HA能显著降低磷吸附量,pH为4.5时分别加入100和40 mg/L HA,磷的最大吸附量分别降低了26.6%和25.6%;pH为7.0时分别加入100和40 mg/L HA,磷的最大吸附量分别降低了26.8%和23.1%. 不同添加顺序试验结果表明:针铁矿对磷的吸附量大小顺序为后添加HA>同时添加HA和磷>先添加HA;无论是否添加HA,针铁矿对磷的吸附量都随着pH的升高而降低,相应的吸附等温线也都符合Langmuir吸附等温方程;总有机碳和红外光谱特征表明,HA和磷在针铁矿表面吸附点位形成竞争吸附,并且针铁矿表面的羟基在吸附磷和HA的过程中起到了一定的作用.
