Determination of Ni,Co and Mn Content in Ni-Co-Mn Ternary Cathode Material by Potentiometric Titration
The test methods was established to get the content of Nickel,cobalt and manganese in Ternary cathode material by Potentiometric Titration is studied.The DETA was used to determinate the total content of three metal.The content of Mn was test by potassium permanganate,the content of Co was back titrated by Potassium ferricyanide and the content of Ni was gain by subtraction method.The Potentiometric Titration results show that the recovery of the method is between 98.5%~101.3%,the relative standard deviation is less than 0.66%.The method has the advantage of good accuracy,good repeatability,actual and an appropriate choice of analysis conditions.
