An improved flow-based procedure for microdetermination of total tannins in beverages with minimized reagent consumption
(SPRINGER WIEN, 2008)
A flow system designed with solenoid micro-pumps is introduced for spectrophotometric determination of total tannins based on the Folin- Denis reaction. The procedure minimizes the main drawbacks related to the AOAC batch ...
Effects of ultrasonic irradiation on the spectrophotometric determination of nickel with dimethylglyoxime
(2001)
Influence of ultrasonic waves in the spectrophotometric determination of nickel with dimethylglyoxime (DMG) was investigated and interferences from foreign species such as Co2+, Fe2+ and Cu2+ were studied. A 1.5-fold ...
Método colorimétrico para determinação de dióxido de nitrogênio atmosférico com preconcentração em coluna de c-18
(Sociedade Brasileira de Química, 2002-05-01)
An alternative analytical method for nitrogen dioxide (NO2) in atmosphere was developed. The collection of NO2 is performed by a Sep-Pack C-18 cartridge impregnated with 11% (v/v) of triethanolamine plus 3,6 % (v/v) of ...
