ality and crystallography of mineral surfaces involved, and the total concentration of the metal or oxyanion Sorptive interactions at the solid–water interface strongly influence present. However, most nutrient oxyanions and trace the bioavailability of many important nutrient oxyanions and trace metals occur at relatively low concentrations in natural contaminant metals in both natural and eng...

Cadmium (Cd) isotopes provide new insights into Cd uptake, transport and storage mechanisms in plants. Therefore, the present study adopted the Cd-tolerant Ricinus communis and Cd-hyperaccumulator Solanum nigrum, which were cultured under controlled conditions in a nutrient solution with variable Cd supply, to test the isotopic fractionation of Cd during plant uptake. The Cd isotope composition...

A study of regeneration of the ion exchange resins using a sub-critical mixture of CO2-H2O solution was reported. The experimental data were obtained by measuring the outlet concentration of ions Cd eluated from a column packed with a commercial ion exchange resin Amberlite IRC-86 until the effluent reached the input concentration. The adsorption isotherm was also reported. The correlation of t...

We report on a facile and rapid microwave-assisted method for preparing a sodium-cadmium metal-organic framework (having coordinatively unsaturated sodium ions) that considerably shortens the conventional synthesis time from 5 days to 1 hour. The obtained (Na,Cd)-MOF showed an excellent volumetric CO2 adsorption capacity (5.2 mmol cm(-3) at 298 K and 1 bar) and better CO2 adsorption properties ...

Largish molecules on metal surfaces may act as not only the building blocks of 2D self-assemblies, but also template to reshape surfaces. Here, we report molecular adsorption-induced formation periodic nanostripe arrays substrate atoms through long-range mass transport. When adsorbed close-packed Cd(0001) surface, triphenyl bismuth (TPB) form a self-assembly with 4 × √13 reconstruction. Simulta...

Heavy metal pollution in soil has seriously affected the living environment of human beings Among all heavy pollution, cadmium (Cd) is one most difficult to migrate pollutants soil. Therefore, this systematic review includes remediation techniques Cd-contaminated groundwater that using. Different techniques, including pump and treat, permeable reactive barrier, adsorption, biosorption, electroc...
