Mathematical equation correction to spectral and transport interferences in high-resolution continuum source flame atomic absorption spectrometry: Determination of lead in phosphoric acid
(2010-01-01)
In this work, a new mathematical equation correction approach for overcoming spectral and transport interferences was proposed. The proposal was applied to eliminate spectral interference caused by PO molecules at the ...
Internal standardization and least-squares background correction in high-resolution continuum source flame atomic absorption spectrometry to eliminate interferences on determination of Pb in phosphoric acid
(Pergamon-Elsevier B.V. Ltd, 2008-09-01)
In this work the least-squares background correction (LSBC) and internal standardization (IS) techniques were combined to eliminate spectral and transport interferences in the determination of Pb in phosphoric acid by ...

Effects of superficial liming and silicate application on soil fertility and crop yield under rotation
(2013-03-01)
Soil acidity and low natural fertility are the main problems for grain production in Brazilian 'cerrado'. Although lime has been the most applied source for soil correction, silicate may be an alternative material due to ...

Effects of surface application of dolomitic limestone and calcium-magnesium silicate on soybean and maize in rotation with green manure in a tropical region
(Instituto Agronômico de Campinas, 2015)
Although lime is currently the material most frequently used to ameliorate soil acidity in Brazil, silicate could efficiently replace this source because of its greater solubility and its greater silicon content, which are ...
