摘　　要：探究碱性改性的生物质炭对印染工业污水中甲基橙的吸附性能。结果表明:改性竹笋生物质炭具有大的比表积和丰富的孔结构,其对15 mL 30 mg·L^(-1)的甲基橙在210 min后达到平衡,最佳投加量和最大吸附量分别为7 mg·L^(-1)和64.1 mg·g^(-1),吸附动力学更加符合准二级动力学模型。The adsorption performance of alkaline modified biomass carbon for methyl orange in printing and dyeing industrial wastewater was explored.The results showed that the modified bamboo shoot biochar had large specific surface area and rich pore structure.It reached equilibrium after 210 min for 15 mL of 30 mg·L^(-1) methyl orange,and the optimal dosage and maximum adsorption capacity were 7 mg·L^(-1) and 64.1 mg·g^(-1) respectively.The adsorption kinetics was more in line with the quasi second-order kinetic model.
