摘　　要：活性炭是一种具有很高吸附性能的固体材料,在环境保护、资源循环利用等方面有广阔的应用前景。青稞秸秆是高原地区农作物秸秆资源的主要部分,其可再生性和环境友好性使其在废水处理领域具有巨大的应用潜力。利用青稞秸秆制备活性炭是一种廉价、易操作的方法。本文通过响应曲面法,以甘南地区青稞秸秆为原料,采用化学活化法制备出了具有较高吸附性能的青稞秸秆活性炭,并探讨了活化温度、活化时间和物料比对吸附性能的影响。结果表明,最优制备条件为活化温度600℃、活化时间60 min、物料比(青稞秸秆与ZnCl_(2)质量比,下同)1∶3。Activated carbon is a kind of solid material with high adsorption performance,which has broad application prospects in environmental protection,resource recycling and other aspects.Highland barley straw is the main part of crop straw resources in plateau areas,and its renewability and environmental friendliness make it have huge application potential in the field of wastewater treatment.The preparation of activated carbon from highland barley straw is a cheap and easy-to-operate method.In this paper,the highland barley straw activated carbon with high adsorption performance was prepared by chemical activation method using highland barley straw as raw material in Gannan area by response surface methodology.The effects of activation temperature,activation time and material ratio on the adsorption performance were discussed.The results show that the optimal preparation conditions are activation temperature 600℃,activation time 60 min and material ratio 1∶3.
