Spectrophotometric determination of carbon dioxide and sulphur dioxide in wines by flow injection

Abstract: Abstract. Flow injection analysis (FIA) methods for the spectrophotometric determination of CO 2 and SO 2 in wines are described. The determination of CO 2 is based on the colour change of a low capacity buffer (containing an acid-base indicator) due to the dissolved carbon dioxide. The determination of SO 2 is based on the decoloration of malachite green by sulphur dioxide. Two FIA manifolds are presented; one for the determination of CO 2 in sparkling wines and another for the simultaneous determination of C… Show more

“…Sulfur is determined by a variety of techniques, including gravimetric [29,30] and volumetric [31] methods, UV-vis spectrometry [32][33][34][35][36][37], IC [38], combustion IC [39], XRF [40,41], ICP-MS [42,43] and ICP OES [44]. Similar to phosphorus, UV-vis spectrometry is among the most widely used techniques for the determination of sulfur, but requires extensive sample preparation und is subject to various interferences from other ions.…”

“…Sample pretreatment is only required for releasing bound SO2 and it consists of a basic hydrolysis. Gas diffusion (Azevedo et al, 1999;Silva et al, 1998;Kuban et al, 1998;Araujo et al, 1998;Su et al, 1998;Decnop-Weever and Kraak, 1997;Lin and Hobo, 1996;García-Prieto et al, 1994;Thanh et al, 1994;Huang et al, 1992;Bartroli et al, 1991;Mana and Spohn, 2001;Segundo and Rangel, 2001;Segundo et al, 2000;Cardwell and Christophersen, 2000;Atanassov et al, 2000) is the most common separation technique if removal of the analyte from the matrix is required. The use of this technique provides slightly higher average precision (2.3% vs. 3.3%) than do other separation techniques such as pervaporation Mataix and Luque de Castro, 1998), evaporation (Zhi et al, 1995), or ion exchange (Richter et al, 1993).…”

“…Biocatalyzed (Huang et al, 1992;Rezende and Mottola, 1994;Fatibello-Filho and da Cruz Vieira, 1997;Yao et al, 1994) or redox reactions using H2O2 (Su et al, 1998;Huang et al, 1992;Pérez-Ruiz et al, 1993) and I2 (Kuban et al, 1998;Lin and Hobo, 1996;Thanh et al, 1994) as oxidants are also used. Amperometric (Azevedo et al, 1999;Thanh et al, 1994; Rezenda and Mottola, 1994;Cardwell et al, 1993; Cardwell et al., 1991b) and photometric detectors (Kuban et al, 1998;Decnop-Weever and Kraak, 1997;García-Prieto et al, 1994; Bartoli et al, 1991;Segundo, 2000;Atanassov et al, 2000;Mataix and Luque de Castro, 1998;Zhi et al, 1995;Richter and Luque de Castro, 1993; Fatibello-Filho and de Cruz-Vieira, 1997, Pérez-Ruiz et al, 1993) have been widely used with similar frequency, providing similar accuracy and precision. Less common is the use of potentiometric (Araujo et al, 1998; Mataix and Luque de Castro, 1999) and chemiluminescence detectors (Lin and Hobo, 1996;Huang, et al, 1992).…”

“…Most flow injection analyses are adaptations of other existing methods, mainly spectrophotometric methods. Application of FIA systems for both the malachite green (Atanassov et al, 2000;Bendtsen and Jorgensen, 1994) and p-rosaniline (Fernandes et al, 1998) methods are known. The sample is injected into the carrier stream which contains NaOH for on-line release of bound sulfites.…”
