摘要
采用示波极谱滴定法测定土壤中氮的质量分数,与其他方法相比,具有快速准确、终点直观、用样量小的特点,溶液的颜色、产生的沉淀对测定均无影响.
An Oscillopolarographic titration method for the determination of potassium in soil samples was studied. The determination isn't affected by the solution colour and precipitation. The characteristics of the method are quick, exact, saving and easy to observe the final results.
