Laser-induced breakdown spectroscopy: Extending its application to soil pH measurements
(2015-06-23)
Acid-base equilibria are involved in almost all the processes that occur in soil. The bioavailability of nutrients for plants, for instance, depends on the solubilization of mineral nutrients in the soil solution, which ...

Quantitative Raman determination of hydrogen peroxide using the solvent as internal standard: Online application in the direct synthesis of hydrogen peroxide
(Elsevier Science Sa, 2011-02)
H2O2 concentrations in aqueous solutions have been determined by means of a 532nm Raman spectrometer. H2O2 is a highly demanded green oxidant agent, and its direct synthesis from H2 and O2 is a promising alternative to the ...
