摘　　要：研究了HDX 8树脂对苯酚的吸附性能 ,最大静态吸附容量为 2 2 3.5mg/g .柱长 1 0cm ,内径 1 .0cm ,内装HDX 8树脂的吸附柱 ,在酸性条件下 ,能有效地吸附水中的痕量酚 ,负载柱可用 0 .1mol/LNaOH溶夜定量解吸 ,富集倍率达 1 0 0 .研究认为 ,HDX 8吸附树脂既可有效去除水中酚污染 。Adsorption effects of HDX 8 resin for trace phenols were studied in detail.The dynamic adsorption capacity was 223.5 mg/g(dry resin).Trace phenols in pH2 water could be enriched by a column packed with HDX 8 adsorption resin and 0.1 mol/L NaOH solution was used as the eluant.The enrichment factor exceeds 100.The resin could be used for determining or removing trace phenols water.
