m~2/g. X-ray fluorescence spectrum analysis (demonstrates) that 0.6% Y exists in the mesoporous structure of Y-MCM-41. The conclusion has also been confirmed by FT-IR which shows an increase in intensity of the peak of Y-MCM-41 at (963.90?cm~(-1).)
The superficial characteristics of iridium-doped gold jewelry and the occurrence and the chemical compositions of doped material in gold jewelry have been investigated by using optical microscopy and X-ray fluorescence spectrum analysis.
Regularization Procedure for the Fundamental Parameters Method in X-ray Fluorescence Analysis
The spectral intensity of the brightest (Kα, Lαand, less frequently, Mαor Mβ) lines of the characteristic X-ray spectrum serves as the second analytical signal, which is conventionally used in X-ray fluorescence analysis.
Sources of Error in Total Reflection X-Ray Fluorescence Analysis and Error Correction Using the Internal Standard Method
An analytical equation is proposed for the fluorescence intensity excited in total reflection X-ray fluorescence analysis.
It was proposed to use the ultrasonic pretreatment before the extraction-X-ray fluorescence analysis of water to eliminate the effect of humic substances on the recovery of elements.
