摘要/Abstract

摘要： 以花生壳为基体,锥形瓶为反应装置,在300 ℃下热解4 h,制备了花生壳基生物炭.在此基础上,进一步对其进行了功能化,合成了疏水性较强的赋硫生物炭.同时采用Bohem滴定、红外光谱和紫外光谱对所得赋硫生物炭的官能团进行了表征和分析,并对影响赋硫生物炭吸附性能的主要因素进行了系统考察.结果表明:同一功能性生物炭在不同时间和温度的制备条件下呈现出不同的吸附性能,而不同官能团的功能炭对有机污染物的吸附能力也不同,赋硫生物炭在同等条件下显示出最强的吸附效果,可以有效消除废水中的苯系有机物.此制备方法原料易得,成本低,制备过程简单,所得材料吸附性能好,在处理废水中有着很强的应用价值.

Abstract: In a conical flask, biochar was prepared by pyrolysised reaction method,with peanut shell as material and temperature at 300 ℃ for 4 h. The obtained biochar was further functionalized with sodium sulfide. The results indicated that the same biochar had different adsorption properties under different time and temperature conditions. The functionalized biochar with different functional groups showed different adsorption capacity to organic pollutant. Among them, the functionalized biochar contains S-hetero-atomic functional groups showed the strongest adsorption effect. The method improved the preparation of biochar, reduced the cost, simplified the process, and enhanced the adsorption capacity.

Key words: functionalized biochar, peanut shell, wastewater purification, organic removal
