| 摘 要： | 铝盐是工业生产及城市给水处理中广泛使用的无机盐,随废水排入江河中,造成水体污染。已经证实铝与老年痴呆症和甲状腺亢进等疾病有关,过多摄入还会导致人体免疫力下降,小儿智力低下及行为异常1]。因此,我国在新制订的《城市供水行业2000年技术进步发展规划》中,将铝列为常规监

| Abstract: | A new method for concentrating and separating inorganic aluminum in environmental water by means of cotton-fibriform loading-polyamide resin was developed.The resin was prepared through the reaction of polyamide resin powder with ice acetic acid and 8-hydroxyquinoline.The optimum absorption medium for aluminum were at pH 3-4(adjusted with nitric acid) and the eluent used was 0.1 mol/L sodium hydroxide.Under optimum experimental conditions,the adsorption capacity of Al~(3+) on the loading-polyamide resin with 8-hydroxyquinoline was 8.0 mg/g.The Al concentration in the solution was determined by Chrome Azurol S spectrophotometry.This method has been successfully applied to the determination of Al in environmental water samples.The recoveries of Al ranged from 93% to 102%. |
