【摘要】 为了有效去除废水中Cu²⁺,以牛粪为原料，制取生物炭，采用等温吸附法及动力学吸附法研究生物炭对废水中的Cu²⁺的吸附效果，并通过XRD、FTIR、BET与元素分析等进行表征。结果表明：热解温度、时间、pH是影响生物炭产率及吸附量的因素。700℃制备的牛粪生物炭（CDB700[2h]）对废水中的Cu²⁺吸附量是最高，达到了0.623 mg·g^-1,去除率达到了99.7%。说明，CDB700[2h]具有作为废水中Cu²⁺吸附材质的潜力，本研究为生物炭去除废水中重金属污染的修复提供了理论依据与应用参考。更多还原

【Abstract】 In order to effectively remove Cu²⁺ from wastewater, biochar was prepared from cow dung. The adsorption effect of biochar on Cu²⁺ in wastewater was studied by isothermal adsorption method and kinetic adsorption method, cow dung biochar were studied by XRD, FTIR, BET and elemental analysis. The results showed that pyrolysis temperature, time and pH were the factors affecting the yield and adsorption capacity of biochar. The adsorption capacity of Cu²⁺ in wastewater by cow dung biochar（CDB700[2 h]） prepared at 700℃ was the highest, reaching 0.623 mg·g^-1, and the removal rate was 99.7%. Therefore, CDB700[2 h]has the potential to be used as Cu²⁺ adsorption material in wastewater. The theoretical basis and application reference were provided for the remediation of heavy metal pollution in wastewater by biochar.更多还原
