【摘要】 以Fe3+标准溶液为滴定剂,在乙醇-水体系中用光度滴定法测定二茂铁的含量。对溶剂的选择、酸度影响、反应时间、滴定曲线等测定条件和方法应用进行了研究和讨论。利用该方法对实际样品进行测定,回收率为98·5%~99·2%。结果表明,本方法能够快速、准确地测定二茂铁的含量,成功地用于产品的检测。更多还原

【Abstract】 A rapid,convenient and accurate method for the determination of ferrocene was established. The content of ferrocene was measured by spectrophotometric titration method with Fe~ 3+ standard solution as titrant in the ethanol-water system. The determination conditions such as the choice of solvent,pH value of system,reaction time and titration curves, and the application of the method were studied and discussed. Two real samples was determined with recovery of 98.5%-99.2%. The experiment results showed that the method was rapid and accurate for the determination of ferrocene product.更多还原
