Direct Determination of Phosphite in Fertilizers by Amperometric Titration
(Amer Chemical Soc, 2009-01-28)
Amperometric titration using two Pt microelectrodes for the determination of phosphite in fertilizers based on the oxidation of analyte by iodine is proposed. The influence of pH, buffer composition, temperature, and foreign ...
Non-aqueous Titration of Gatifloxacin in Pharmaceutical Formulations using Perchloric Acid
(2003-10-01)
An inexpensive, simple, precise and rapid method for the determination of fluoroquinolone gatifloxacin in tablets is described. The procedure is based on the use of volumetric dosage in a non-aqueous medium in glacial ...
Método titrimétrico para determinar fosfito em amostras agroindustriais
(Sociedade Brasileira de Química, 2007-04-01)
A new titrimetric method for the determination of phosphite in fertilizer samples, based on reaction of H3PO3 with standard iodine solution in neutral media, is proposed. Diluted samples containing ca. 0.4% m/v P2O5 are ...

Titulacao do sevoflurano utilizando o indice bispectral em anestesia pediatrica. Influencia da medicacao pre-anestesica no tempo de despertar e no consumo de anestesico inalatorio
(2000-01-01)
Background and Objectives - Sevoflurane is an inhalational anesthetic drug with low blood/gas solubility providing fast anesthesia induction and emergence. Its ability to maintain cardiovascular stability makes it ideal ...
Immune Response to the Rhodococcus equi infection in high and low antibody-producing mice (selection IV-A)
(2005-11-10)
Rhodococcus equi is a Gram-positive, facultative intracellular bacterium which infects macrophages and causes rhodococcal pneumonia and enteritis in foals. Recently, this agent has been recognized as an opportunistic ...
Phosphite determination in fertilizers after online sequential sample preparation in a flow injection system
(Amer Chemical Soc, 2007-07-26)
A flow injection spectrophotometric system is proposed for phosphite determination in fertilizers by the molybdenum blue method after the processing of each sample two times on-line without and with an oxidizing step. The ...
Direct determination of phosphite in fertilizers by flow-injection amperometry
(Wiley-Blackwell, 2007-09-01)
A sensor based on graphite electrode modified with palladium-platinum-palladium film is proposed for phosphite determination by flow-injection amperometry. The modified electrode was prepared by a sequential cathodic ...
Flow injection amperometric determination of persulfate in cosmetic products using a Prussian Blue film-modified electrode
(2003-12-01)
A flow-injection system with a glassy carbon disk electrode modified with Prussian Blue film is proposed for the determination of persulfate in commercial samples of hair bleaching boosters by amperometry. The detection ...
