Determination of Aluminum, Iron, Potassium, Magnesium, Manganese,Titanium in Wollastonite by ICP-AES Method
-
Abstract
Samples are dissolved by hydrochloric acid.Perchloric acid was added into the solution to enhance temperature and evaporate.The crystal salt was dissolved by hydrochloric acid.The six impure elements of aluminum,iron,potassium,magnesium,manganese,titanium in solution were determined by inductively coupled plasma atomic emission spectrometry.The effect of matrix silicon on the six elements determination was studied.And the effect was avoided by adding hydrofluoric acid.Wollastonite certified standard material and samples were tested.The testing relative standard deviation was less than 5%.The determination values of wollastonite certified standard material was consistent with its standard values.Testing process didn't exist obvious systematic errors.The recovery rate was between 92% ~ 105%.And the determination values are reliable.The method is applicable in rapid determination of impure elements in wollastonite. -
