摘　　要：在利用吸附法处理印染废水的吸附材料中,农林废弃物以其来源广泛、可再生、环境友好和使用后处理简单等特性,具有潜在的应用价值和经济价值。本文以农业废弃物藜麦秸秆粉(QSP)作为吸附剂,对含罗丹明B(RhB)的模拟废水进行吸附性能研究。当RhB溶液的初始浓度为150 mg/L,吸附温度为35℃,溶液pH为3,吸附时间为140 min,QSP浓度为6 g/L时,其吸附量和脱色率分别为49.04 mg/g和65.39%。QSP的多孔结构和表面上丰富的含氧基团是其吸附RhB的主要原因。Among the adsorbent materials used for treating dyeing wastewater via the adsorption method,agricultural and forestry wastes have potential application and economic value due to their wide availability,renewability,environmental friendliness,and simple postuse treatment.This study investigates the adsorption performance of agricultural waste quinoa straw powder(QSP)as an adsorbent for simulated wastewater containing Rhodamine B(RhB).When the initial concentration of the RhB solution was 150 mg/L,the adsorption temperature was 35°C,the solution pH was 3,the adsorption time was 140 minutes,and the QSP concentration was 6 g/L,the adsorption capacity and decolorization rate were 49.04 mg/g and 65.39%,respectively.The porous structure of QSP and the abundant oxygencontaining functional groups on its surface are the main reasons for its adsorption of RhB.
