Chelation removal of heavy metals from contaminated soil is seen as a viable remediation technique. A useful chelating agent should be strong, reusable, and biostable during metal extraction and recovery operations. This work tested the extraction, recovery, and biostability of EDTA as a potential ...
The relation between the metal contents in plants and the different fractions of the metal in soil was evaluated through linear correlations. Different results were obtained, the forms accounting for the metal in celery are those of the metal bound to iron oxides, while the metal content in ...

This study was carried out to examine heavy metal accumulation in rice grains and brassicas and to identify the different controls, such as soil properties and soil heavy metal fractions obtained by the Community Bureau of Reference (BCR) sequential extraction, in their accumulation. In Guangdong ...
the breakthrough volume of the compound of interest is a limiting factor for sensitivity in SPE; when the volume of sample that can be passed through the SPE bed exceeds the retention capacity of the extraction sorbent, analytes are not quantitatively retained by the sorbent anymore, resulting in...

Access through your organization Section snippets Origin of fly ash and sample preparation The leaching experiments were performed with fly ash from two MSWI plants in Switzerland (Table 1). Both plants are using the FLUWA process and in addition to their own fly ash they also treat fly ash...
Refers to evaporation of shallow groundwater into the atmosphere directly from the soil through the porous ground surface. Salar Salars (Spanish term for salt lake or salt flat) are endorheic sedimentary basins containing thick sequences of continental evaporites and clastic deposits. Salar de Atacama...
