摘　　要：通过苯甲酰基修饰的苯乙烯-二乙烯苯吸附树脂ZH-02对水中腐殖酸和苯酚进行了单组分和双组分的静态吸附。结果表明,在腐殖酸为主要吸附质的二元组分溶液中,对苯酚的吸附量的影响可以利用IAST模型进行预测;而在不存在主要吸附质的二元溶液中,可以用单组分体系的平衡吸附量近似预算双组分竞争体系时各组分的平衡吸附量。The static adsorption of humic acid and phenol from water in single and double component system onto ZH-02 resin of styrene-divinylbenzene modified by benzoyl group was carried out. The results show that the adsorption capacities of phenol in double component system in which humic acid is the main adsorbate can be calculated by IAST model while the adsorption capacities of each component in competitive system having no main adsorbate may be predicted by those in single component system.
