Spectroscopic measurements of soil samples are reliable because they highly repeatable and reproducible. They characterise the samples' mineral–organic composition. Estimates concentrations constituents inevitably less precise than estimates obtained conventionally by chemical analysis. But cost each spectroscopic estimate is at most one-tenth a determination. Spectroscopy cost-effective when w...
biocl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (mw) assisted synthesis method for 23 minutes at 180 w. scanning electron microscopy (sem) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. the x-ray diffraction (xrd) pattern showed that a highly pure and crystalline phase has been obtained. the energy ...
This paper describes a green analytical procedure for the determination of bumetanide using diffuse reflectance spectroscopy. The proposed method is based on reflectance measurements of a violet compound produced from a spot test reaction between bumetanide and p-dimethylaminocinnamaldehyde (p-DAC) in an acid medium, using filter paper as a solid support. The best conditions for the reaction ha...
