A highly sensitive colorimetric determination of serum zinc using water-soluble pyridylazo dye.

T Makino et al.

Clinica chimica acta; international journal of clinical chemistry, 120(1), 127-135 (1982-03-26)

A colorimetric method for precise and accurate determination of zinc in serum is presented. Only 0.3 ml of sample is necessary, because of the use of a new, highly sensitive reagent, 2-(5-bromo-2-pyridylazo)-5-(N-n-propyl-N-3-sulfopropylamino)-phenol (epsilon 554nm = 1.3 X 10(5) 1 .

Formation of a liquid organic ion associate in aqueous solution and its application to the GF-AAS determination of trace cadmium in environmental water as a complex with 2-(5-bromo-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol.

Noriko Hata et al.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 24(7), 925-928 (2008-07-11)

The formation of a liquid organic ion associate in an aqueous sample was applied to the concentration and determination of cadmium in environmental water samples. Cadmium was converted into a complex with 2-(5-bromo-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol (5-Br-PAPS) in a 40-mL sample solution, and

Adsorptive voltammetry of 2-(5-bromo-2-pyridyl)azo-5-[N-n-propyl-N-(3-sulfopropyl)amino]phenol on a carbon paste electrode in the presence of organic cations and polycation.

Toshiaki Hattori et al.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 22(12), 1577-1580 (2006-12-13)

The adsorption of ion-association complexes on a carbon paste electrode (CPE) was investigated by cyclic voltammetry using an electroactive hydrophobic anion probe. The redox reactions of 2-(5-bromo-2-pyridyl)azo-5-[N-n-propyl-N-(3-sulfopropyl)amino]phenol (5-Br-PAPS), the analytical probe, were irreversible. The reduction of the azo group and
