摘要
对硝基苯酚在各个领域中都有着重要的作用,但由于其本身属于酚类,具有较强的毒性,使用不当会造成严重的污染。本研究以花生壳为原料,采用热解法在400、500、600℃下制备花生壳生物炭,研究不同操作条件下花生壳生物炭对废水中对硝基苯酚的吸附能力。研究结果表明,在不同热解温度下的花生壳生物炭对对硝基苯酚溶液的吸附能力随热解温度的升高而增强。生物质炭吸附能力随对硝基酚的投加量增加而降低,随着花生壳生物质炭的投加量的增加而增加。600℃下所制得的生物炭对浓度为10 mg/L的对硝基苯酚溶液的吸附能力最强,且在中性环境下,去除率可以达到100%。
p-Nitrophenol plays an important role in various fields,but improper use can cause serious pollution.In this study,peanut shells were used as raw materials,and peanut shell biochar was prepared by pyrolysis at 400,500and 600℃.The adsorption capacity of peanut shell biochar on p-nitrophenol in wastewater was studied under different operating conditions.The results showed that the adsorption capacity of peanut shell biochar prepared at different pyrolysis temperatures on p-nitrophenol solution increased with the increase of pyrolysis temperature.The adsorption capacity of biomass carbon decreased with the increase of the dosage of p-nitrophenol,and increased with the increase of the dosage of peanut shell biomass charcoal.The biochar produced at 600℃ showed the strongest adsorption capacity for p-nitrophenol solution with the concentration of 10 mg/L,and the removal rate reached 100% in a neutral environment.
