the chemical extraction of twenty-nine elements in a washing aggregate sludge, a clay-richsediment, a sewage sludge, the mixtures of these materials and the artificial lightweight aggregates (lwas)manufactured with them was determined by applying the optimized european community bureau of reference sequential extraction procedure in order to establish the effect of the thermal treatment on the ...

Selective Sequential Extractions (SSE) were used to study the retention mechanisms of heavy metals on three estuarine alluvium soil columns obtained from leaching experiment for up to 5 pore volumes (PV). Leaching results indicate that almost 99 % of heavy metals (Pb, Cu, and Zn) were retained in the soils with the Ce/Co values in the order of 10 -3 to 10. This is in accord with the results obt...

background: the analysis of heavy metals at trace level is one of the main toxicologists concern, due to their vital rules in human`s life. cadmium is one of these toxic heavy metals, which released to the environment from various industries. methods: in order to determine cd (ii) ions in various matrices magnetic ion-imprinted polymer (iip) method has been developed and applied. this nano-sorb...

this study was conducted in assaluyeh region, southwest of iran to show utilization and efficiency of sequential extraction analysis in environmental impact studies using soil and related regolith materials as sample media. in order to investigate distribution of heavy metals, optimized bcr (community bureau of reference) sequential extraction analysis method was used. in this caseeight repres...

the effect of temperature on the adsorption of heavy metals on not only natural bulk clay, but also for the individual phases that composed the bulk clay sample, was investigated. combined adsorption- sequential extraction analysis (casa) for pb, cu, zn and cd were conducted under various temperatures that ranged from 150c to 550c. as a result, it was found that heavy metals adsorption for bulk...

background and purpose: the heavy metal pollution and its fractionations in the surface sediments of darreh-morad beyg river, hamedan city were monitored for cd, cr, cu, fe, ni, pb, and zn in 2014.   materials and methods: totally 30 surface sediment samples were taken from 10 stations with three replicates. the samples subjected to bulk digestion and chemical partitioning. the concentrations o...
