    摘要:

    为了探究碱改柚子皮生物炭在实际应用中去除水体中Mn(Ⅱ)的可行性，考察了其在固定床中对Mn(Ⅱ)的动态吸附。以流量、床高、Mn(Ⅱ)初始浓度为变量，研究了这三类运行条件对碱改柚子皮生物炭在固定床中吸附Mn(Ⅱ)的影响，并对实验结果进行了模型拟合，结果表明：碱改柚子皮生物炭对Mn(Ⅱ)的吸附有一定的缓冲作用；降低流量和Mn(Ⅱ)初始浓度，增加床高均能使固定床的运行时间延长；在流量为1mL/min，Mn(Ⅱ)初始浓度为150mg/L，床高为2cm时，观察到了碱改柚子皮生物炭对Mn(Ⅱ)的最大比吸附量为25.59mg/g；Thomas模型表明内部扩散和外部扩散不是吸附过程中的限制性步骤；在Adams–Bohart模型的拟合中发现固定床系统吸附初期的动力学受外部传质控制，且其线性表达式（BDST模型）较为准确的预测了各初始条件下Mn(Ⅱ)穿透70%的运行时间；modified dose-response模型准确的描述了Mn(Ⅱ)穿透曲线的形状。研究显示，碱改柚子皮生物炭有在固定床实际应用中去除水体中Mn(Ⅱ)的潜力。

    Abstract:

    In order to study the feasibility of Mn(Ⅱ) removal in water by alkali modified pomelo peel biochar in practical use, whose dynamic adsorption of Mn(Ⅱ) in a fixed bed was implemented. The effects on alkali modified pomelo peel biochar adsorbed Mn(Ⅱ) in a fixed bed by flow rate, bed height and Mn(Ⅱ) initial concentration were researched, and the data were fitted by varying models, the results showed that the adsorption of Mn(Ⅱ) by alkali modified pomelo peel biochar possessed a buffering action to some extent; the fixed bed operation time was prolonged with the decrease of flow rate and Mn(Ⅱ) initial concentration and increase of bed height, the highest adsorption capacity of alkali modified pomelo peel biochar for Mn(Ⅱ) was 25.59mg/g, which was obtained in flow rate was 1 mL/min, Mn(Ⅱ) initial concentration was 150mg/L and bed height was 2cm; the Thomas model indicated that internal and external diffusion weren’t control procedure in the process of adsorption; the Adams–Bohart model suggested the adsorption preliminary kinetic in the fixed bed was controlled by external mass transfer, its linear expression (the BDST model) predicted the operation time of effluent Mn(Ⅱ) concentration reach 70% of influent Mn(Ⅱ) concentration in each condition with comparatively accuracy; the modified dose-response model described the shape of the Mn(Ⅱ) breakthrough curve accurately. The research indicated that there was potential to removed Mn(Ⅱ) for alkali modified pomelo peel biochar in a fixed bed practical use.
