Kinetic study of the decomposition of hydrogen peroxide catalysed by Co(II) acetylacetonate supported on a silica-propylpiperazine matrix
(Elsevier Science BvAmsterdamHolanda, 1998)
Alkene epoxidation with iodosylbenzene catalysed by polyionic manganese porphyrins electrostatically bound to counter-charged supports
(Royal Soc Chemistry, 2001-01-01)
Manganese(III) complexes of tetra-anionic and tetra-cationic porphyrins have been immobilised on counter-charged, surface-modified silica supports and on organic ion-exchange resins. The reactions of these supported ...
Determination of tellurium at ultratrace levels in drinking water by on-line solid phase extraction coupled to graphite furnace atomic absorption spectrometer
In this paper, two time-based flow injection (FI) separation pre-concentration systems coupled to graphite furnace atomic absorption spectrometry (GFAAS) for tellurium determination are studied and compared. The first ...
Multivariate calibrations for the SR-TXRF determination of trace concentrations of lead and arsenic in the presence of bromine
(John Wiley & Sons LtdChichesterInglaterra, 2006)
Determination of the betaine content of feed ingredients using high-performance liquid chromatography
A series of studies was conducted to establish a methodology for the accurate and efficient determination of betaine in different feed ingredients. The final methodology involves an extraction step in which the feed sample ...
