  • 摘要: 以栗苞炭化料（C-BC）为原料，以NaOH为活化剂制备栗苞活化生物质炭（Na-BC），研究其对水中亚甲基蓝的吸附行为。选取炭碱比、活化温度和活化时间为影响因素，通过正交试验确定了最佳活化工艺，即炭碱比为1：4，活化温度为800℃，活化时间为30 min，此时Na-BC的最大吸附量为609.38 mg·g-1。对最优条件下制备的生物质炭进行SEM、BET等表征，比表面积达1 563.78 m2·g-1，总孔容达1.452 cm3·g-1。吸附实验结果显示，吸附反应能较好用Langmuir模型和准二级动力学方程模型进行模拟，Na-BC对亚甲基蓝的吸附为自发吸热反应。通过热法与碱法再生处理饱和吸附生物质炭，再生后的Na-BC对亚甲基蓝具有较好的吸附能力。
    Abstract: Activated bio-char (Na-BC) was prepared by the activation of chestnut bud bio-char (C-BC) using NaOH,and its adsorption behavior towards methylene blue in water was examined.The optimum activation conditions,namely the alkali carbon ratio (1:4),activation temperature (800℃),and activation time (30 min),were determined by orthogonal testing.Under these conditions,the maximum adsorption capacity of Na-BC was 609.38 mg·g-1.The prepared Na-BC particles were characterized using scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET) analysis.The BET surface area and the total pore volume were 1 563.78 m2·g-1 and 1.452 cm3·g-1,respectively.In the adsorption tests,the kinetic curves of Na-BC fit well with the pseudo second-order kinetics model,while the equilibrium isotherm data fit well with the Langmuir equation.Furthermore,the adsorption of methylene blue on Na-BC is a spontaneous endothermic reaction.Finally,following regeneration of Na-BC by alkaline solution and thermal treatment,Na-BC continued to exhibit a high adsorption capacity for methylene blue.
