不同样品中游离二氧化硅分析研究进展

Research progress in the analysis of free silica in different samples

游离二氧化硅主要是指岩石或矿物中没有与金属或金属化合物结合而呈游离状态的二氧化硅,本文总结了近些年来不同样品中游离二氧化硅分析研究现状。目前可用于分析游离二氧化硅的方法主要有:重量法、红外光谱法、X射线衍射法、拉曼光谱技术、氟硅酸钾容量法、紫外可见分光光度法以及电感耦合等离子体发射光谱法等。

Free silica mainly refers to the silica in rocks or minerals that is in a free state without binding with metals or metal compounds.This article reviews the current research status of free silica analysis in different samples in recent years.At present,the main methods available for analyzing free silica include:gravimetric method,infrared spectroscopy,X-ray diffraction,Raman spectroscopy,potassium fluorosilicate volumetric method,UV visible spectrophotometry,and inductively coupled plasma emission spectroscopy etc.
