Use of cationic surfactant-xylenol orange indicator in metals complexometry by back-titration with EDTA.
(Editora Unesp, 1996-01-01)
The interaction of the xilenol orange and commercial disinfectant containing itself cationic-surfactant allowed the use indicator up to pH 11 by back-titration with EDTA, and the determination of total or partial concentration ...

Determination of bicarbonate in substrate extracts using back-titration and the Gran Plot approach
(Taylor & Francis IncPhiladelphiaEUA, 2005)
Studying current-potential curves throughout a bipotentiometric iodometric back-titration for the determination of ascorbic acid in fruits and vegetables
(American Chemical Society, 2004-12)
A method for the determination of the ascorbic acid content in fruits and vegetables was used to introduce the principles of voltammetry. The procedure combines an iodometric back-titration with voltammetric (bipotentiometric) ...
Bentazon Determination by Conductometric Titrantion Using Acid Hydrocholoric as Titrant
(Brazilian Chemical Soc, 2016-01-01)
Bentazon is an active principle of post-emergence herbicides used to control weeds in several crops of oilseeds, leguminous and cereals. Commercial formulations of these herbicides are found as concentrated solutions of ...
Comparative analysis of exchangeable aluminum in a tropical soil under long-term no-till cultivation
(2022-02-01)
Aluminum toxicity is a key determinant of crop yield for acid soils. Techniques used to characterize a soil's exchangeable Al content often yield discordant results, thus impeding the implementation of corrective measures. ...
Utilização do indicador alaranjado de xilenol - Surfactante catiônico em titulação complexométrica por retorno de metais com EDTA em região básica
(1996-12-01)
The interaction of the xilenol orange and commercial disinfectant containing itself cationic-surfactant allowed the use indicator up to pH 11 by back-titration with EDTA, and the determination of total or partial concentration ...
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 ...
