  • 摘要: 为有效去除饮用水中天然有机物，提高水处理效果，本研究对比分析了合成镁铝水滑石及其在200℃、500℃和800℃下的焙烧产物对腐植酸、富里酸在不同pH与温度影响下的吸附去除性能及机理。结果表明，吸附效果有明显的差别，吸附不是简单单分子层物理吸附，存在一定程度的化学作用机理。其中500℃焙烧产物对腐殖酸与富里酸的吸附效果最好，对HA与FA的最大吸附量分别为105.2 mg/g和100.3 mg/g。
    Abstract: To effectively remove the natural organic matter from drinking water, the adsorption efficiency and mechanism of humic acid (HA) and fulvic acid (FA) on the synthesized hydrotalcite and the three calcined products under different temperatures and pH values were fully investigated. Results showed that significant differences in the adsorption efficiency existed between the four hydrotalcite adsorbents, physical monolayer adsorption constituted the main adsorption mechanism, and some chemical reactions were also observed.The optimistic one was obtained under the calcinations temperature of 500℃, and the maximum adsorbent capacity were 105.2 mg/g and 100.3 mg/g for the HA and FA,respectively.
