比较了一种合成吸附剂与颗粒活性炭（GAC）对含有天然有机物（NOM）的地下水中三氯乙烯（TCE）的去除性能。采用吸附平衡、动力学和中试实验对吸附剂进行了比较。吸附等温线研究表明，在10-2000 ug/L的TCE浓度范围内，合成吸附剂的TCE容量是GAC的三到四倍。当预先暴露在含有NOM的地下水中24周时，合成吸附剂的容量比在原始吸附剂上执行的单一溶质等温线平均损失12%；广汽集团在仅10周的预曝光时间内，其处女产能平均下降35%。快速的小规模柱试验和模型计算预测了合成吸附剂的中试工厂出水曲线。中试数据证实，合成吸附剂在去除TCE方面比GAC更有效。 包括17个参考文献、表格、图表。

The performance of a synthetic adsorbent in removing trichloroethene (TCE) from a groundwater containing natural organic matter (NOM) was compared with that of granular activated carbon (GAC). Adsorption equilibrium, kinetic, and pilot-plant experiments were used to compare the adsorbents. Adsorption isotherm studies showed that the synthetic adsorbent had three to four times more TCE capacity than GAC over a TCE concentration range of 10-2,000 ug/L. When preexposed for 24 weeks to a groundwater containing NOM, the synthetic adsorbent showed an average 12 percent loss in capacity compared with the single-solute isotherm performed on the virgin adsorbent; GAC showed an average 35 percent loss in its virgin capacity for a preexposed time of only 10 weeks. Rapid small-scale column tests and model calculations predicted pilot-plant effluent profiles for the synthetic adsorbent. The pilot-plant data confirmed that the synthetic adsorbent is more efficient than GAC in removing TCE. Includes 17 references, tables, figures.
