We tried to prepare activated carbons (ACs) suitable for removing pollutants in aqueous phase from the points of textural properties and surface chemistry. Examining various carbon precursors and activated procedures, ACs prepared from bamboo using H3PO4 activation successfully achieved specific surface area of 2000 m2/g and meso-pore volume of 0.9 cm3/g. The meso-pore rich AC accommodated greater amount of large size molecules such as dye than conventional commercial meso-pore AC. Kinetics of heavy metal adsorption could also be improved by meso-pore AC. Changing carbon precursors and treating methods for carbon surface using oxidants and ammonia gas, carbon surface was switched from hydrophobic to hydrophilic nature and significant increase in heavy metals adsorption was observed, whereas AC structure was sometimes destroyed by the treatments.

我们试图制备适合从质地性质和表面化学点中去除水相的污染物的活性碳（ACS）。使用H3PO4激活来检查各种碳前体和激活程序，成功实现了2000 m2/g的特定表面积和0.9 cm3/g的特定表面积。与传统的商业中孔AC相比，中孔富的AC容纳更多的大尺寸分子，例如染料。中孔AC也可以改善重金属吸附的动力学。使用氧化剂和氨气的碳前体和处理碳表面的方法的变化，碳表面从疏水性转换为亲水性质，并且观察到重金属吸附的重量显着增加，而AC结构有时会被处理破坏。
