Quick Analysis of Organic Amendments via Portable X-ray Fluorescence Spectrometry

Determining the Content of Silicon Dioxide in Bauxites Using X-Ray Fluorescence Spectrometry

The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method,  and the formation of beads. Certified reference bauxite samples were used for the cali...

Multielement analysis of soft drinks by X-ray fluorescence spectrometry.

Several commercial soft drinks and respective plastic bottles were analyzed for their multielement contents employing the synchrotron radiation total reflection X-ray fluorescence spectrometry technique (SRTXRF). The SRTXRF method has been developed and validated, and about 20 elements were detected in the investigated samples, including some trace elements, which can be toxic for human beings,...

Multivariate Data Analysis for X-ray Fluorescence Spectrometry

A multivariate data analysis procedure that uses singular value decomposition and the Ho-Kashyap algorithm is proposed to obtain calibration constants for x-ray fluorescence spectrometry. These calibration constants can be used to obtain results from experimental data by means of a simple dot product calculation. The method was tested on experimental data from the literature. Comparison of resu...

Field portable X-Ray fluorescence for rapid analysis Of titanium dioxide on air filters

Field portable X-Ray fluorescence for rapid analysis Of titanium dioxide on air filters. ii ACKNOWLEDGMENTS This study would not have been possible without the help from several different resources. I would like to thank Kent Candee for the access to the field portable x-ray fluorescence analyzer, which was my biggest concern from the beginning of the project. I would also like to thank Pam Kos...
