In this study, the alpha-quartz contents measured by different analytical techniques X-ray diffraction, direct method and infrared spectrophotometry, direct and indirect methods were compared. The analyses were carried out on filters sampled in an industrial setting by means of a Dorr-Oliver cycl
Dec 01, 2020 In the extraction, it was aimed to transfer the water insoluble analyte complex to the extraction solution, where the solubility of analyte complex is high. In the extraction, pH 9.0 borate buffer solution 0.50 mL and 1.0 mL of E-2,4-dibromo-6-3-hydroxyphenyliminomethylphenol solution 0.025 wv were added into a 15 mL centrifuge ...
Rhyolitic melt that fuels explosive eruptions often originates in the upper crust via extraction from crystal-rich sources, implying an evolutionary link between volcanism and residual plutonism. However, the time scales over which these systems evolve are mainly understood through erupted deposits, limiting confirmation of this connection. Exhumed plutons that preserve a record of high-silica ...

In this work, a novel, efficient, simple and green solid phase extraction SPE method based on a pipette tip filled with zirconium nanoparticles Zr-NPs was developed for the sensitive determination of cobalt in soil samples via slotted quartz tube-flame atomic absorption spectrophotometry SQT-FAAS. Zirconium nanoparticles providing repeatable and reproducible signals of the analyte were ...
Dec 21, 2019 In this study, comprehensive laboratory experiments, such as thin-section and optical section analyses and P wave velocity and uniaxial compression tests, are performed on three types of quartz mica schist samples. The thin-section analysis reveals that the schist predominately consists of flaky mica and granular minerals, including quartz, feldspar, and calcite.
