Construction of a polymeric liquid-membrane ion-selective electrode (ISE) and its application for determination of nitrate in tomatoes
(2004)
A potentiometric all-solid-state type ion-selective electrode (ISE) for NO3 - was constructed and characterized. It is based on a mixture of tetra-decyl-ammonium nitrate (TDAN) as ionophore, di-butyl phthalate (DBP) as ...
Model to predict the chloride penetration in concrete with profile forming peak: verification of its precision
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2009)
Chloride attack in marine environments or in structures where deicing salts are used will not always show profiles with concentrations that decrease from the external surface to the interior of the concrete. Some profiles ...
The use of sodium-chloride difference and chloride-sodium ratio as strong ion difference surrogates in the evaluation of metabolic acidosis in critically ill patients
(W B SAUNDERS CO-ELSEVIER INC, 2010)
Purpose: Inorganic apparent strong ion difference (SIDai) improves chloride-associated acidosis recognition in dysnatremic patients. We investigated whether the difference between sodium and chloride (Na+-C1-) or the ratio ...
Influência do uso de resíduo de vidro no concreto contaminado por íons cloreto, íons sulfato e CO2.
(Universidade Católica de Pernambuco, 2019-12-19)
Concrete structures have their performance directly related to the
conservation of mechanical properties and properties linked to
durability. Regarding durability, it is possible to mention the action of
three agents ...
A poly(vinyl chloride) membrane electrode for the determination of the diuretic furosemide
(Marcel Dekker IncNew YorkEUA, 2004)
Cobalt(II) tetrasulfophthalocyanine complex adsorbed on a silica gel surface chemically modified with 3-N-propylpyridinium chloride: Oxalic acid oxidation study
(Wiley-v C H Verlag GmbhBerlinAlemanha, 1999)
Simultaneous determination of no3 – and no2 – in fisheries wastewaters high in chloride concentration by capillary ion electrophoresis with direct uv detection
(1997)
The simultaneous determination by capillary ion electrophoresis of nitrate and nitrite in wastewaters with chloride concentrations of 15 to 23 g/l is described. Chloride concentrations over 200 mg/l hampered the determination; ...
