摘要:
研究了在不同温度下制备的3种芦苇生物炭的基本理化性质及表观性能,以及不同时间、初始溶液pH值、初始溶液Pb2+浓度下这3种生物炭吸附率的变化。结果表明:对于3种生物炭的制备,随着温度升高,生物炭产率降低,灰分升高,pH值升高;随着热解温度升高,芦苇生物炭的C、N含量随之增加,而O、H含量随之降低;BET比表面积、Langmuir比表面积、T-plot微孔比表面积、BJH吸附累积比表面积均表现为L500>L700>L300;从生物炭对氮气吸附的量上看,存在L500>L700>L300的规律;吸附试验表明,500 ℃下制备的生物炭L500的吸附效果最佳,最佳吸附条件是初始溶液pH值为6,吸附时间为150 min,吸附温度为25 ℃。
