“…In this study, the possibility to use HCl as supporting electrolyte was valued and it does not cause any problem to Au surface. Using medium exchange technique, the result obtained was in good agreement with the known concentration (recovery 99.8 %) reported by Detcheva and Grobecker who used this and other reference materials to validate a spectroscopic method [11]. The concentration of mercury found by SW-ASV was also in excellent agreement with that obtained by AAS-GF.…”

“…Initially, the analytical performance of AuNPs-GCS on synthetic solutions containing known as mercury concentrations were evaluated determining linearity, repeatability, accuracy and sensitivity. Then, the reliability of the technique was tested on a sample of fish known as Tuna fish ISPRA T22: this sample has been adopted by Detcheva & Grobecker [11] to validate analytical procedures and its Hg content is reported in literature. To verify Hg concentration in this sample, an Atomic Absorption Spectroscopy with Graphite Furnace atomizer (AAS-GF) was also used to optimize the instrumental response for this matrix.…”

Abstract:The applicability of a gold nanoparticle-modified glassy carbon sensor (AuNPs-GCS) for the determination of inorganic mercury in fresh and canned tuna fish by square wave anodic stripping voltammetry (SW-ASV) is demonstrated. Mercury content in sample Tuna Fish ISPRA T22 was determined to value the accuracy of the determination. The concentration in this sample is not certified, so, the Hg amount was determined also with atomic absorption spectroscopy (AAS): the results obtained with ASV were in good agreement and confirmed literature value reported for this sample. Then, real samples of tuna fish were analyzed. The voltammetric analyses were performed using previously optimized conditions (deposition potential 0 V, step potential 0.004 V, frequency 150 Hz and amplitude 0.003 V). Medium exchange technique permitted to eliminate possible matrix effects. The concentrations in the real samples were found to be in agreement with the common Hg levels reported in literature for commercialized tuna fish in different countries.

“…According to Brazilian Residues and Contaminants Control Plan in Fish, PNCRC/2010(Instrução Normativa Nº 8, MAPA 2010, the concentrations limits in the fish muscle are 0.1 mg kg -1 for Cd and 0.2 mg kg -1 for Pb in natura. The determination of Cd and/or Pb in the fish and shrimp has been successfully carried out by inductively coupled plasma emission spectrometry (ICP OES) (Heu et al 2003;Ersoy and Çelik 2010;Morgano et al 2010;Yilmaz and Yilmaz 2007;Pourang and Dennis 2005), ICPmass spectrometry (ICP-MS) (Pourang and Dennis 2005;Falcó et al 2006) and graphite furnace atomic absorption spectrometry (GF AAS) (Detcheva andGrobecker 2006, Gaspic et al 2002;Dural et al 2007;Tuzen 2003). However, the methods by ICP OES usually are not sensitive enough for checking the mentioned concentration limits, requiring pre-concentration procedures.…”

“…3 For the direct analysis of solid samples during the last years, the use of solid sampling electrothermal atomic absorption spectrometry (SS-ETAAS) has been reported. 1,[8][9][10][11] This method shows interesting advantages. Solid sampling requires a very small amount of a sample (usually a few milligrams), and little or no sample pretreatment.…”

An electrodeposited palladium and iridium/gold mixture has been investigated as a chemical modifier for mercury determination in environmental samples by solid sampling electrothermal atomic absorption spectrometry. Electrochemical procedures of platform surface modification performed in a cell with 20 ml of solution, and in a drop of modifier solution have been optimized. Simple electrolysis in a drop was found to be the most consistent, taking the reproducibility as the major criterion. A total mass of 250 μg of electrodeposited palladium or an iridium/gold mixture was used. The lifetime of 60 -70 firings for a deposited iridium/gold mixture was smaller than that for palladium with a lifetime of 100 -120 firings. The detection limit was 120 pg Hg. Different sample masses of between 0.1 and 10 mg were weighed into modified platforms according to the mercury content. The results obtained for mercury in environmental samples as soils, sediments and plant, using solid sampling and calibration against aqueous standards stabilized by potassium permanganate, were in good agreement with those achieved by using the thermal deposition of modifiers and with measurements by pyrolysis atomic absorption spectrometry with gold amalgamation.
