摘要
采用电位滴定法测定汽油中硫化氢和硫醇的含量，检测范围是１．０×１０－６～１．２×１０－３。同时还介绍了电极制作的新方法，采样及计算终点的数学公式。此方法准确性好，简便，易于操作。适用于液态烃中硫化氢和硫醇的检测。
Potentiometric method is used to determine contents of hydrogen sulfide and mercaptan in gasoline.The detection limit ranges from 1.0×10 -6 to 1.2×10 -3 mol/L.It also presents a new method for making electrode,sampling and a mathematical formulas for calculating the end point. The method is rapid,accurate and easy to operate and is suitable for determining hydrogen sulfide and mercaptan in liquid hydrocarbons.
