以废弃的猪骨为原料制备的多孔炭作为吸附剂,分析了其对含Cr工业废水的净化作用,并对其吸附机理进行探讨。结果表明,吸附体系的pH、吸附时间、Cr(Ⅵ)初始浓度对多孔炭吸附Cr(Ⅵ)的能力影响较大,多孔炭材料的比表面积对其吸附水溶液中的Cr(Ⅵ)起决定性作用。该吸附过程符合二级动力学吸附模型,并且可用Langmuir吸附等温线来描述。所以猪骨基多孔炭有望成为含Cr(Ⅵ)废水的良好净化剂。 Porous carbon prepared from waste pork bone was used as adsorbent to purify the industrial wastewater containing Cr, and its adsorption mechanism was discussed. The results showed that pH, adsorption time and initial Cr (Ⅵ) concentration of adsorption system greatly influenced the ability of porous carbon to adsorb Cr (Ⅵ). The specific surface area of ​​porous carbon material played a decisive role in its adsorption of Cr (Ⅵ) in aqueous solution . The adsorption process conforms to the second-order kinetic adsorption model and can be described by the Langmuir adsorption isotherm. Therefore, pig bone-based porous carbon is expected to be a good scavenger containing Cr (Ⅵ) wastewater.
