针对水体突发铍污染事故,采用4种常用应急处置材料蒙脱土粉、活性炭粉、高岭沸石粉及硅藻土粉作吸附剂,考察其对Be^(2+)的去除效果。结果表明,活性炭粉反应优化p H为6,35℃时对Be^(2+)的吸附容量达到最大,其他三者对Be^(2+)的吸附反应优化p H为8,吸附效果受温度影响小。随反应时间延长,投加量减少,四者对Be^(2+)吸附容量上升。处理同一铍含量废水时,优化投加量蒙脱土粉

Aimed at the sudden beryllium pollution accidents in water bodies, four kinds of commonly used emergency disposal materials montmorillonite powder, activated carbon powder, kaolinite powder and diatomite powder as adsorbents, to investigate their removal efficiency for Be2+. The results showed that, the optimum pH of the activated carbon powder reaction was 6, and the adsorption capacity of Be2+ was maximized at 35 ℃. The optimum pH of other three adsorption reactions was 8, and the adsorption effect was less affected by temperature. With the ...
