摘要
本文用盐酸水溶液对海泡石进行酸处理、450℃下焙烧制得改性海泡石。然后将其用于对重金属离子Zn2+的吸附,考察了PH值、初始浓度、时间对吸附效果的影响,绘制的吸附等温线较好地符合Langmuir吸附等温方程。
A new adsorbent modified meerschaum was obtained while meerschaum was burned in 450℃ after treated by hydrochloric acid solution. This sorbent was used to adsorb heavy metals （Zn^2＋ ） ions, the effect of PH value of solution, initial concentration of heavy metal cations, time of adsorption on adsorption reaction were investigated respectively.
