Determination of ZrO_2 and TiO_2 in Alkali-Resistant Fiberglass Mesh by ICP OES

摘要

A new method was studied for the determination of ZrO_2 and TiO_2 in alkali-resistant fiberglass mesh by ICP-AES. The sample was pretreated by acid-soluble and alkali-fusion methods. The corresponding concentration of three times of standard deviation (3S) was used to calculate the detection limit of the method, and the detection limit was from 0.0018% to 0.0047%. The corresponding concentration of ten times of standard deviation (10S) was used to calculate the quantitation limit of the method, and the limit of quantitation was from 0.0060% to 0.016%. The relative standard deviations (RSDs (n=6)) of the test were from 0.60% to 0.78%. Compared to standard method, absolute error was less than 0.2% and the relative error was less than 2.0%. The results showed that the method can be used for simultaneous determination of ZrO_2 and TiO_2 in alkali-resistant fiberglass mesh., with fast analysis and reliable results.
