Studies on the Determination of Element Potassium in Plant by Ahematin Current Oscillopolarngraphy
示波极谱滴定法测定植物中钾含量的研究

A alternating currnet oscillopolarography method for the determination of potassium element in plant is described, based on Na-TPB titration. The method is simple, rapid and sensitive. The end point of titration is clear. The proposed procedure is applied successfully to the determination of element potassium in plant.
