AI Article Synopsis
- * A series of methods were used to pre-treat the sample before determining various elements (like Be, Cu, and others) using ICP-AES, a technique for elemental analysis.
- * Results showed high recovery rates (93.3%-102.1%) and low variability (relative standard deviations of 0%-3.56%), indicating the method’s efficiency and accuracy in assessing lithium hexafluorophosphate products.
Article Abstract
One gram (+/- 0.0001 g) of lithium hexafluorophosphate was weighed exactly under dry atmosphere and was dissolved with an adequate amount of dimethyl carbonate (DMC). After the sample solution was pretreated with a series of methods, Be, Cu, Pb, Ca, Zr, Co, Mg, V, Ti, Mo, Ni, Mn, Sr, Zn, K, Al, Ba, Cd, Fe, Cr and Na were determined by ICP-AES. The results show that the recoveries of standard addition were 93.3%-102.1%, and the relative standard deviations (n = 11) were 0%-3.56%. The method is efficient, accurate and easy to operate. It has been applied to the determination of lithium hexafluorophosphate products with satisfactory results.
