摘要:
以芦苇为研究对象,采用负载铁盐的方法制备新型铁改性生物质炭,用于水体中硝态氮的去除。结合扫描电镜和红外光谱分析对芦苇生物质炭进行表征,探究不同改性方法、铁炭比、芦苇生物质炭投加量、pH值和共存离子等因素对芦苇生物质炭吸附硝态氮的影响,分析芦苇生物质炭的吸附动力学与吸附等温线特性。结果表明,超声静置的铁改性芦苇生物质炭记为CS-LWC吸附能力最强,在200 mL初始浓度为20 mg/L硝态氮溶液中投加1.4 g CS-LWC,对氮的去除率为85.28%;酸性条件有助于铁改性芦苇生物质炭对硝态氮的吸附,而共存阴离子Cl-、H2PO4-、CO32-会抑制其吸附;CS-LWC对水体中硝态氮的吸附过程符合准二级动力学模型,其饱和吸附量为3.442 mg/g;吸附行为与Langmiur等温模型相符,为单层吸附。
