摘　　要：探讨了用改性香蕉皮吸附处理活性艳橙模拟废水的效果,结果表明:1∶1(体积比)硫酸改性香蕉皮的吸附性能较好。用改性香蕉皮吸附活性艳橙的最适宜条件为:常温、pH=2,吸附时间30 min,振荡速率190r/min,吸附剂用量3.5 g/L,初始浓度为5 mg/L,此时最大脱色率达96.7%,处理后的滤液为无色。The adsorption of simulated reactive brilliant orange wastewater with modified banana peels was discussed. The result showed that banana peels modified by sulfuric acid （volume ratio 1：1） had good adsorption abili- ty on reactive brilliant orange. And the optimum conditions of adsorption reactive brilliant orange were obtained. When the initial concentration of reactive brilliant orange was 5 mg/L, the pH value was 2, the dosage of adsorbent was 3.5 g/L, the decolorization ratio could reach 96.7% after absorpting for 30 min with oscillation rate 190 r/min at room temperature, and the treated filtrate was colorless.
