Abstract This study provides the surface characteristics (surface energy and the acid–base properties) of surface treated activated carbons (ACs) using inverse gas chromatography. The surface energy and the acid–base characteristic of studied adsorbents are determined by the retention time using several non-polar and polar probes at 140 °C. It is observed that the dispersive surface energy dominates for all AC samples. The treatment of Maxsorb III with H2 exhibits the highest basicity due to lower oxygen content on the surface. The presented results express further insights and useful information in functionalizing the activated carbon for various industrial applications.

使用反气相色谱法研究高多孔母体和表面处理活性炭的表面能和酸碱性质

摘要 本研究使用反相气相色谱法提供了表面处理活性炭 (AC) 的表面特性（表面能和酸碱特性）。所研究的吸附剂的表面能和酸碱特性由在 140 °C 下使用几种非极性和极性探针的保留时间确定。观察到色散表面能在所有 AC 样品中占主导地位。由于表面氧含量较低，用 H2 处理 Maxsorb III 表现出最高的碱度。所呈现的结果表达了将活性炭用于各种工业应用的功能化方面的进一步见解和有用信息。
