“…1) indicated that the oxides minerals are not important for immobilisation of the metal. The published data pointed out that lead in presence of oxides minerals is mainly bound to this phase (Jakubowska et al 2006; Krasnodȩbska-Ostrȩga et al 2001; Sutherland and Tack 2007). The extractability discussed above and the results obtained using SEM–EDS revealed that metal fraction associated with reducible minerals is not important for immobilisation of lead in the studied bottom sediments.…”

“…The immobilisation of trace metals depends on the presence of Mn–Fe oxides phase in solid matrix (Fletcher 1981; Krasnodȩbska-Ostrȩga et al 2001), which was reflected by the poor immobilisation of Cd, Cu, Pb, Tl and Zn observed in the bottom sediment with low organic content. In these cases, the reducible and oxidable phase content is too low to effectively take part in the immobilisation of those metals (Jakubowska et al 2006). It could suggest that the mechanism of Tl association with the sediment matrix rich in carbonates and sulphides in the absence of oxides and organic matter was similar to the mechanism of Pb.…”

Mobility of toxic elements in carbonate sediments from a mining area in Poland

et al. 2014

View full text Add to dashboard Cite

The Bolesław–Bukowno mining area in Poland is highly polluted by elements such as Zn, Pb, Cd and As. The reactivity and mobility of toxic elements such as Tl are poorly known. Here, we studied by sequential extraction the mobility of As, Cd, Co, Cr, Cu, Mn, Mo, Pb, Tl and Zn in sediments from two water reservoirs near Bukowno. Results show that available As, Co, Mn, Pb and Zn are found in carbonate minerals. Available Cd, Cu and Tl are found in sulphides and organic matter. The extractability of As, Cr, Mo and Tl was rather poor. By contrast, 85 % of total Cd, Pb and Zn was mobile. We discuss Tl and Mo association in carbonate sediments from ore deposits.

“…A lack of suitable analytical methods seems to be a significant barrier in collecting more reliable data in this area. An incomplete extraction of thallium from soil by aqua regia is an additional factor hindering the better understanding of thallium mobility in the environment [16].…”

Flow‐Injection Differential‐Pulse Anodic Stripping Voltammetry as a Tool for Thallium Monitoring in the Environment

et al. 2010

In order to demonstrate the applicability of the Flow-Injection Differential-Pulse Anodic Stripping Voltammetry to monitoring of thallium in the environment, thallium concentration in water, bottom sediments and the soil of floodplain terraces of two rivulets were investigated. It is shown, that thallium containing particles are transported by rivulets and are deposited in bottom sediments (7.4 and 1.7 mg g À1 downstream, respectively). Thallium originating from this source is dispersed in flood-plain valley soil and is dissolved in rivulet water. Thallium concentration in water (0.32 and 0.21 mg L À1 downstream , respectively) exceeds the normal level by 20 -30 times.

“…Graphite furnace atomic absorption spectrometry [9,10] flow injection-differential pulse-anodic stripping voltammetry [11] cathodic and anodic stripping voltammetry [12][13][14], electrothermalatomic absorption spectrophotometry [15,16] inductively coupled plasma mass spectrometry [17][18][19][20] and thermal neutron activation analysis [21] are the most popular analytical techniques used for the determination of thallium at trace levels. However, these techniques are disadvantaged by the long duration, matrix effects, expensive facilities and their maintenance.…”

Determination of thallium in environmental samples by surfactant assisted dispersive liquid-liquid microextraction combined with first order derivative spectrophotometry

2015

A surfactant assisted dispersive liquid-liquid microextraction (SA-DLLME) combined with derivative spectrophotometric method has been proposed for the determination of thallium(III) using a chelating agent diacetylmonoxime-p-hydroxybenzoylhydrazone. Disperser solvent was substituted by surfactant, which made the emulsification more effective and extraction, quite environment friendly. Carbon tetrachloride was employed as the extractant. The developed SA-DLLME technique was coupled with first order derivative spectrophotometric method to improve the analytical performance. Optimum conditions relevant to SA-DLLME and instrumental parameters were studied in detail. The enrichment factor of the method was found to be 23. The limit of detection and quantitation limit of first order derivative spectrophotometric method were found to be 0.22 and 0.67 µg/L, respectively. The relative standard deviation (RSD) for five replicates of 50.0 µg/L of thallium(III) was found to be 1.12%. The applicability of the method was evaluated by the trace level determination of thallium in different environmental samples.
