Methods for Determining Magnesium Content in Silica-based Materials with ICP(Inductively Coupled Plasma)Spectrometer
In the paper,the detection method of magnesium content in silica-based composite material is studied and its purpose is to accurately detect magnesium content in the process of preparing silica-based composite materials so as to control the content of magnesium silicate in final product.During the experiment,the method for determining magnesium content in magnesium silicate-carbon-encapsulated silicon oxide composite material with the inductively coupled plasma atomic emission spectrometry(ICP-AES)is established.Finally,it is verified that the detection limit is 0.004 mg/L,relative standard deviation of detection results is less than 5%and linearly dependent coefficient is above 0.999 so that this method is satisfied with the test of magnesium content.
