Second,the difference of hydrogen peroxide and Sb was determined by iodometry.
利用H2O2既具有还原性又具有氧化性这一特殊性质,用硫酸铈滴定法测定溶液中H2O2和Sb(的总量,用碘量法测定溶液中H2O2和Sb(的差量,用硫酸铈滴定法在近沸温度下测定溶液中的总Sb量,最后计算得出H2O2,Sb(和Sb(的量。
Using Agilent 8453 ultraviolet-visible spectrophotometer,the affecting factors were studied on the kinetic processes in iodometry involved in the volatilization of iodine and the oxidation of iodide ion by dissolved oxygen,in particular such as the shape of the vessel,the volume of the solution tested,the concentration of KI and the temperature and the acidity of tested solution.
通过大量数据和图形,形象直观地从定量的角度阐述了碘量法中控制实验条件的重要性。
