| 摘 要： | 研究了在β-环糊精(β-CD)和乳化剂OP(聚乙二醇辛基苯基醚)存在下,Fe(Ⅲ)-苯基荧光酮(PF)的显色反应,建立了分光光度法测定微量铁的新方法.结果表明:该配合物在最大吸收波长560nm测试条件下,表观摩尔吸光系数由无β-CD时的6.36×104L.mol-1.cm-1提高到1.02×105L.mol-1.cm-1,铁含量在0.0~8.0μg/25mL范围内服从比尔定律.本方法用于自来水中微量铁的测定,结果令人满意.

| Abstract: | The colour reaction of ferrum with pehnylfluorone system,in the presence of β-CD and OP,has been studied in this paper.A spectrophotometric method has been developed for determination of ferrum.The result shows:The maximum absorbance is at 560 nm with apparent molar absorption of 1.02×105 L.mol-1.cm-1.The beer,s law is obeyed in the range of 0.0~8.0μg/25mL.The contents of ferrum in water were determined by the new method with satisfactory results. |
