Mobility of Heavy Metals in Soil Profiles

Removal of heavy metal ions from dilute aqueous solutions by polymer–surfactant aggregates: A novel effluent treatment process

“…These ions tend to accumulate in organisms, causing numerous diseases and disorders (Kim et al, 2006). In wastewater treatment, treatment processes for toxic metal-contaminated water have received much interest in recent years in order to comply with stringent regulations, which are caused by direct contamination in water and indirect the subsoil mobility of ions (Kurniawan et al, 2006, Domergue andVédy, 1992). Due to the requirement of discharge concentrations for heavy metal ions to be at ppb levels, dilute heavy metal ion removal processes, such as chemical precipitation (Charerntanyarak, 1999;Mólgora et al, 2013), ion exchange (Inglezakis et al, 2005), adsorption (Najafi et al, 2012), biosorption (Ajjabi and Chouba, 2009) and membrane filtration (Hafiane et al, 2000;Hankins et al, 2005, Hankins et al, 2006, have been widely researched.…”

Effect of soil application of cadmium contaminated lime on soil cadmium distribution and cadmium concentration in strawberry leaves and fruit

“…The limited leaching of this element to greater depths is a well known phenomenon (5,9) which can, however, be conducive to Cd uptake by surface rooted plants.…”

Fractionation and Speciation of Trace Elements in Soil Solution

“…The use of ion-selective electrodes for trace element speciation purposes has remained somewhat limited due to their low sensitivity. Moreover, trace element analyses using ion-selective electrodes often suffer from interferences [76][77][78]. Ion-selective Cu electrodes are generally more sensitive and selective than other ion-selective metal electrodes (for example Cd, Pb and Zn).…”
