Impact of surface modification on binding affinity distributions of Datura innoxia biomass to metal ions

Article Abstract:

Results revealed that carboxyl groups are the main factors that govern the metal binding by the Datura innoxia biomass. Other functionalities, however, are also responsible for the metal binding by the biomass. The continued increase in the measured amount of methanol released suggest that methyl etherification of hydroxuls on the biomass could have also occurred. It is inferred that the binding capacity of the biomass is reduced as esterification is increased.

Utilization of biomass residues for the remediation of metal-polluted soils

Article Abstract:

Biomass residues such as molasses, blood meal and silage effluents prove useful as extractants in the remediation of metal-polluted soils. Grass silage effluent effectively removed -75% of Cd and >50% of Cu and Zn at pH 4.4. The neutral blood meal hydrolysate removed about 55-66% of Cu and 38-67% of Ni. Cu and Pb were mobilized by hydrolysates containing sugar acids under alkaline conditions.

Investigation of aluminum binding to a Datura innoxia material using 27Al NMR

Article Abstract:

Aluminum binding to Datura innoxia has been found to be directly related to carboxylate groups at pH 3.5 and at pH 5.0 with direct binding of cell material to an aluminum polymer present at pH 5.0. Soid state nuclear magnetic resonance spectroscopy was used in the experiment and results also suggest that an additional octahedral binding site may be present at a higher pH.
