Phytoextraction is gaining acceptance as a cost-effective and environmentally sound phytoremediation strategy for reducing toxic metal levels from contaminated soils. We hypothesized that the addition of synthetic chelates can increase the amount of bioavailable metal for root uptake, thereby improving the efficacy of phytoextraction. This study was therefore conducted to determine whether the ...

The binding of Cu(II) by histidine in 1: 2 molar ratio has been investigated. The theoretical number of hydrogen ions displaced from each mole of bound llgand at several pH values was calculated considering all the possible interactions between Cu(II) and histidine involving (a) amino and carboxyl, (b) amino and imidazole, (c) imldazole and carboxyl, and (d) amino, imidazole, and carboxyl group...

A series of stable (air, water stable and with good thermal stability) and hydrophobic ionic liquids based upon metal chelate anions were synthesized, which were shown to be effective, mild, and easy to recycle catalysts at the same time stable solvents for the oxidation of cyclohexene.
