interactions between cd, pillared clays and chalcogenedies have been studied using nanomineralogical experiments. xrd, dsc and chemical analysis. the synchrotron-based x-ray absorption spectroscopy (xas) was applied to characterize the reaction phases. the mean bond lengths between, cd-s, fe-s, sb-s, cd-cd (in chalcogenedies), al-cd, cd-ti, and fe-cd, (in pillared clays) were determined by xas ...

Water safety is a prerequisite for sustainable global quantitative and qualitative development. Heavy metal pollution has become major problem in our environment, where traditional heavy processing techniques were unsuccessful expensive. In this study, biochar magnetite have been used as an efficient, low-cost, safe, environmentally friendly method removal such cadmium. The prepared from palm f...

BACKGROUND This study was conducted to estimate the level of heavy metals accumulate in vegetables irrigated with contaminated water compared with those irrigated with fresh water in Hamadan, west of Iran in 2012. METHODS Sixty samples of different vegetables i.e., parsley, tarragon, sweat basil and leek irrigated with contaminated water and thirty six samples from three different adjacent ar...

Cadmium (Cd) concentration in soil solution and its bioavailability is controlled by sorption-desorption reactions. The objective of this research was to compare Cd adsorption behavior in six calcareous and four acid soils. Soil samples were equilibrated with 0.01 M Ca(NO3)2 containing 25 to 3200 mg Cd L−1. Results showed that the tendency for adsorption was high at low Cd concentrations (0-400...

Using treated wastewater for irrigation is a good solution conserving water, but it also in part responsible groundwater and water surface pollution by heavy metals, especially copper cadmium. The soil can be barrier to retaining these pollutants protecting the resource. This study presents an assessment of adsorption cadmium two agricultural soils from Tunisia Romania evaluate risk pollution. ...
