利用花生壳及炭化花生壳作为吸附剂研究对荧光素的吸附情况。试验表明：吸附剂的吸附量在溶液pH为3，吸附时间为8 h时达到最大；分析了该反应体系的热力学过程，两种材料均符合Langmuir和Freundlich吸附模型，R2均大于0．90，Qmax在61．728~303．030 mg/g之间，而且炭化花生壳的最大吸附量显著大于花生壳的最大吸附量， RL均小于1。 Freundlich模型的吸附强度n值在1．218~2．022之间。

The adsorption of fluorescein has been studied with peanut shells and carbonated peanut shell as adsorbent. Experimental results show that when the pH of the adsorption capacity of the catalyst in solution is 3 and adsorption time 8 h,the adsorption capacity is the highest. The thermodynamics process of the reaction system is analyzed. The two kinds of materials are in accordance with Langmuir and Freundlich adsorption models:R2>0.90,and Qmax is between 61.728-303.030 mg/g. The maximum adsorption capacity of carbonized peanut shells is obviously higher than that of peanut shells. RL are all less than 1.Then value of the adsorption strength of Freundlich model is 1.218-2.022.
