A new adsorbent material was prepared by coating an activated carbon with hydrothermal carbon obtained from sucrose. The material obtained has different properties from the sum of the properties of the activated carbon and the hydrothermal carbon, which shows that a new material was obtained. It has a high specific surface area (1051.9 m g) and is slightly more acidic than the starting activated carbon (p.z.c.-point of zero charge 8.71 vs. 9.09). The adsorptive properties of a commercial carbon (Norit RX-3 Extra) were improved over a wide pH and temperature range. The capacity values of the monolayer according to Langmuir's model reached 588 mg g for the commercial product and 769 mg g for the new adsorbent.
一种新的吸附剂材料是通过将水热碳涂覆在活性炭上制得的，水热碳是由蔗糖制备的。所得到的材料具有不同于活性炭和水热碳性质的总和，这表明获得了一种新材料。它具有高的比表面积（1051.9 m 2/g），并且比起始活性炭略酸性（p.z.c.-零电荷点 8.71 对 9.09）。在宽的 pH 和温度范围内，商业碳（Norit RX-3 Extra）的吸附性能得到了改善。根据朗缪尔模型的单层容量值，商业产品达到 588 mg/g，新型吸附剂达到 769 mg/g。
