ICP-OES法测定基板玻璃中铁含量

Determination of Iron Content in Substrate Glass by ICP⁃OES Method

基板玻璃中铁含量是影响玻璃透过率的重要因素之一。利用电感耦合等离子体发射光谱仪(ICPOES)测定基板玻璃中的铁含量,可以改变其对光线的吸收与散射,有助于稳定控制玻璃的质量。本工作从谱线波长选择、提取温度、提取试剂、加标回收实验及精密度等多方面,验证ICP-OES测定基板玻璃中铁元素的准确性和重复性,对指导并改进生产工艺流程具有重要意义。

The iron content in substrate glass affects the glass transmittance.The determination of iron content in substrate glass by inductively coupled plasma-optical emission spectrometer(ICP-OES)helps stabilize glass quality control.The suitable testing conditions for iron element in the substrate glass were explored from the selection of spectral line wavelength,extraction temperature,extraction reagent selection,and combined with the recovery rate and precision of spiking.
