摘　　要：本文以水热KOH溶液处理后的枫香木锯末为吸附材料,对溶液中的亚甲基蓝染料进行吸附去除。采用响应曲面法设计实验,获得的最佳工艺条件为:吸附剂投加量0.24g,染料初始浓度33mg·L^(-1),时间193min,锯末对亚甲基蓝的去除率为98.87%。In this study, maple wood sawdust which treated with hydrothermal KOH solution, was used to remove methylene blue from dye wastewater. Optimization using central composite design （CCD） for adsorption of dye was carried out. Under the optimization conditions as dosage of adsorbent was 0.24g, initial concentration of dye was 33 mg/L, contact time was 193 min, the removal efficiency was 98.87%.
