摘要
以农业副产物花生壳为生物吸附剂，以罗丹明B为吸附对象，探讨了吸附时间、吸附剂用量、初始浓度、盐度离子、溶液pH以及温度等条件对吸附效果的影响。实验结果表明，花生壳对罗丹明B有较好的吸附作用，吸附反应十分迅速，20min基本达到吸附平衡，增大吸附剂用量，吸附率增大，溶液在pH3～5的条件下吸附效果较好，溶液中有Na^＋、K^＋、Ca^2＋和Mg^2＋共存时对花生壳吸附罗丹明B的影响不大，升高温度有利于吸附。
Biosorption effects such as adsorption time, absorbent dosage,initial concentration, salinity ions, pH value and tem-perature on the absorption performances of peanut shell for rhodamine B in water has been investigated. The peanut shell had good adsorption for rhodamine B. The absorption rate was very rapid and it can reach the equilibrium in 20 minutes. The adsorption rate increased with the dosage of the adsorbent. The appropriate pH value was about 3 - 5. There are little effects on the absorption of rhodamine B when there were Na ^＋ ,K^ ＋ , Ca2^＋ and Mg^2＋ ions coexistence. The adsorption performance was benefited to temperature.
