摘　　要： 采用硅藻土作吸附材料制备出改性硅藻土。在静态实验条件下,研究比较了改性前后硅藻土对Sr2+的吸附性能。结果表明:硅藻土经改性处理后,对水溶液中Sr2+的吸附效果明显优于改性前的硅藻土。硅藻土作为一种环境矿物材料,在处理重金属离子等方面具有良好地应用前景。 The modified diatomite was prepared using natural diatomite.Adsorption effects and conditions of strontium ions by modified diatomite and natural diatomite were studied under the condition of static state.The results of the study showed that the removal rate of the modified diatomite was better than that of the natural diatomite.Consequently,diatomite was an inexpensive and readily available adsorbent for strontium ions.
