Metals in wine can originate from natural and anthropogenic sources and their concentrations have significant effects on wine proprieties as well in its conservation. In this work, direct and simultaneous determinations of Zn, Cd, Pb and Cu in wine samples were carried out by differential pulse anodic stripping voltammetry without any steps of previous pretreatment. The samples analyzed presented concentration levels from 4.64 to 69.3 µg L−1 of Zn, from 1.74 to 5.25 µg L−1 of Cd, from 4.57 to 17.9 µg L−1 of Pb and from 1.0 to 10.3 µg L−1 of Cu. Accuracy was evaluated with the standard addition method and recoveries ranged from 82.5 and 130.8% for Zn, from 85.7 to 107.0% for Cd, from 89.7 to 101.0% for Pb and from 81.4 to 105.9% for Cu. With the application of this method, it was possible to quantify the metals in a simple and easy way not requiring sample preparation or other approaches for the destruction of organic substances.

Glassy carbon electrode (GCE) modified by 2-mercaptobenzothiazole (MBT), mesoporous silica (Meso) and bismuth was developed to determine Cd(II) and Pb(II) simultaneously by square wave anodic stripping voltammetry (SWASV). In-situ preparation was found to work best in optimum conditions of acetate buffer pH 6, accumulation potential of -1.1 V, deposition time of 300 s and scan rate of 200 mV/s. SW peaks revealed the linear range of 5-50 µg/L Cd(II) and 5-50 µg/L Pb(II). LOD and LOQ for Cd(II) and Pb(II) were determined as 0.56, 0.80, 1.87 and 2.66 µg/L, respectively. The interaction of metals with bismuth and MBT, as well as higher surface area due to mesoporous silica, support beneficial performance of the modified electrode. Insignificant interferences from other regularly present metal ions were found. With SRM1640 standard, the SWASV results are found comparable to those obtained by inductive coupled plasma optical emission spectrometry (ICP-OES). The method was used to analyze the metals in tap water by standard addition method with the satisfactory recovery of 100.7 % for Cd(II) and 100.8 % for Pb(II).

AbstractA simple and sensitive electroanalytical method was developed for microvolume trace elements determination. Commercially available interdigitated microelectrodes (IDA) from ALS Japan Inc. based on a thin carbon film technology were used. Anodic stripping voltammetry with collection at IDA was applied. Carbon IDA microbands were coated with a pre-deposited mercury film for better performance. The method with this sensor enables analysis of some heavy metals in total sample volumes as small as 0.05 cm3. The method was applied to Pb in blood samples determination by a standard addition method.

Anodic Stripping

In the present communication determination of Zn, Cd, Pb and Cu metals has been carried out from ground water of Hapur District, Uttar Pradesh (India) using differential pulse anodic stripping voltammetry (DPASV) at Hanging Mercury Dropping Electrode (HMDE). Determination of Zn, Cd, Pb and Cu was carried out by using acetate solution as buffer (pH 4.6) with a sweep rate of 0.06 V/sec and pulse amplitude 0.05 V by HMDE by standard addition method. The minimum level of Zn, Cd, Pb and Cu should also be near to zero and the concentration found in the ground water sample of Hapur (India) as analyzed 2.1834, 0.0509, 0.0116 and 0.0331mg/L-1 respectively.

Anodic Stripping

The use of lead and cadmium as internal standards for each other in anodic stripping analysis was investigated. Although accuracy was not affected, precision was significantly improved. The surface active agents Triton-X 100 and starch affected the sensitivity of the anodic stripping procedure for lead and cadmium, leading to error if a calibration curve is used. Data for application of the procedure to the analysis of the marine biological reference material LUTS-1 and soil reference materials SO-2, SO-3, and SO-4 are provided. Key words: internal standard, anodic stripping voltammetry, calibration curve, standard addition, lead determination, cadmium determination.
