将蒸汽活化制备的竹炭和竹活性炭应用于油墨废水处理。与 300 至 700 摄氏度的竹炭相比，800 摄氏度的竹炭对于去除油墨废水中的颜色和化学需氧量 (COD) 效果最好，因为它具有更高的表面积和中孔体积。与 800 摄氏度的竹活性炭 (S800) 相比，600 摄氏度的竹活性炭 (S600) 是最好的，尽管 S800 的表面积 (1108 m(2)/g) 比 S600 (734 m(2)/g) 更大。 S600 具有比 S800 (0.16 cm(3)/g) 更高的介孔体积 (0.20 cm(3)/g)，因此实现了更高的颜色和 COD 去除率。所有竹活性炭均表现出比商业活性炭更高的颜色和 COD 去除效率。此外，S600对亚甲基蓝具有优异的吸附能力（0.89 mmol/g）。因此，竹子是制备去除有机污染物的吸附剂的合适材料。
Bamboo chars and bamboo activated carbons prepared by steam activation were applied for ink wastewater treatment. Bamboo char at 800 degrees C was the best for the removal of color and chemical oxygen demand (COD) from ink wastewater compared to bamboo chars at 300 to 700 degrees C due to higher surface area and mesopore volume. Bamboo activated carbon at 600 degrees C (S600) was the best compared to bamboo activated carbon at 800 degrees C (S800), although S800 had larger surface area (1108 m(2)/g) than S600 (734 m(2)/g). S600 had higher mesopore volume (0.20 cm(3)/g) than S800 (0.16 cm(3)/g) and therefore achieved higher color and COD removal. All bamboo activated carbons showed higher color and COD removal efficiency than commercial activated carbon. In addition, S600 had the superior adsorption capacity for methylene blue (0.89 mmol/g). Therefore, bamboo is a suitable material to prepare adsorbents for removal of organic pollutants.
