透闪石绒对水溶液中Fe^(3+)的吸附研究

Adsorbing Fe^(3+) from Aqueous Solution by Tremolite Clay

以透闪石绒矿物材料为水溶液中Fe^(3+)的吸附剂,考察吸附剂用量、振荡时间、反应温度等对吸附性能的影响。结果表明:吸附剂最佳用量为0.1g;吸附反应在5min后可达到吸附动态平衡;温度变化对吸附性能影响不明显。通过平衡吸附实验获得吸附等温线,符合Langmuir吸附等温式。

The effect of adsorbent quantity, shocking time and temperature on Fea＋ adsorption capacity on tremolite clay was studied. The results showed the best quantity of trernolite Clay is 0. 1 g; the reaction reached balance after 5 min, and isotherms followed the Langmuir Key words, tremolite clay; Fe3＋ change of temperature had little equation.
