“…During the wet sampling periods, the relative abundances of organic matter-bound metals increase slightly. A similar phenomenon was observed by Ettler et al (2006a), who calculated the metal speciation in landfill waters by MINTEQA2, and explained this fact by a dramatic decrease in the alkalinity during precipitation events, followed by a decrease in the metal fraction bound to carbonate complexes. The PHREEQC-2 calculations showed that waters were generally oversaturated with respect to calcite (CaCO 3 ) and undersaturated with respect to other carbonate species.…”

“…Furthermore, HFO and calcite were detected in stream sediments downgradient to the landfill by voltammetry of microparticles (VMP), X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) (Ettler et al 2006a, Ettler et al 2006b. Table 3 reports the results of calculation of the saturation indices (SI) of these phases in landfill A decrease in Eh is not accompanied by an appropriate increase in pH (7.93-8.21) and can be observed immediately after the first precipitation in the precipitation event (Fig.…”

“…The landfill was constructed without any lining preventing leaking of the leachate and served as the principal municipal waste disposal dump between 1984 and 1993 (for details see Ettler et al 2006a). Water samples (n = 55) were taken from tubes draining the landfill leachate and conducting it directly to the small stream during three sampling campaigns: November 2001-December 2002(n = 5), September 2003-January 2004 and January-June 2006 (n = 20).…”

Landfill leachate-polluted stream waters were monitored in three sampling campaigns (November 2001 to June 2006), with emphasis on trace elements. The data were evaluated by means of statistics and speciation modelling. Two statistically different groups of trace elements were distinguished: (1) Ba, Sr, Al, Fe, Mn, Cr, Co, Ni, V, As, Se, Sb, U, Li, Rb and Cs decrease during the rain event due to dilution; (2) Pb, Zn, Cu and Cd increase during the rain event due to the dissolution of hydrous ferric oxides and calcite, on whose surfaces these elements are bound, mainly in the stream sediments downgradient to the landfill.

“…The content of copper was 0.119÷0.360 mg Cu dm -3 , nickel -0.144÷0.992 mg Ni dm -3 , lead -0.190÷0.776 mg Pb dm -3 , and chromium 0.148÷0.710 mg Cr dm -3 . The content of metals in the leachate did not exceed values recorded in other leachate from municipal waste landfills in Poland and worldwide [2,[12][13][14][15][16][17][18][19].…”

Abstract:In the paper the removal efficiency of heavy metals as well as humic compounds, in the treatment of leachate mixed with municipal waste in a sequencing batch reactor was studied. Also, the accumulation of those metals in the activated sludge was examined. It has been shown that the removal efficiency of contamination with humic compounds, for Bx ranging from 0.23 to 0.45 mg COD mg -1 d.m. can reach 71÷74%. An increase in the concentrations of heavy metals in the activated sludge was recorded for Bx in the range 0.23÷1.64 mg COD mg -1 d.m. The amount of heavy metals in the effluent of the SBR in carrying out the process at Bx = 0.23÷0.96 mg COD mg -1 d.m. does not limit their discharge into water and sewer system.

“…The voltammetry of immobilized microparticles was also used for monitoring stream sediment samples in the vicinity of an old, unmonitored municipal landfill in Prague, in the Czech Republic, the aim being to detect the presence of Fe and Mn oxides [71]. The technique proved useful for detecting low concentrations of both goethite and hematite in paleosol and loess samples, where the total content of Fe oxides was <2 wt%, well below the detection limit of powder XRD.…”

Many electrochemical conversions of solid compounds and materials, including for example the corrosion of metals and alloys or the electrochemical conversions of most battery materials, take place within a liquid electrolyte environment, with the classic approach to investigation comprising macro-sized electrodes. However, in order to obtain a comprehensive understanding of the mechanism of these solid-state electrochemical reactions, the simple technique of immobilizing small amounts of a solid compound/material on an inert electrode surface provides an easy, yet sometimes exclusive, access to their study. In this chapter is presented a survey of the recent developments of this approach, which is referred to as the voltammetry of immobilized microparticles (VIM). Attention is also focused on progress in the field of theoretical descriptions of solid-state electrochemical reactions.
