kinetics and equilibrium studies on the biosorption of cr (vi) by vigna subterranean (l.) verdc hull
the vigna subterranean (l.) verdc hull’s (vsvh) potential to remove cr(vi) ions from aqueous solutions was investigated. the biosorbent was characterised by ftir, sem-edx and xrf before and after exposure to cr(vi). the surface comprised of phenolic, carboxylate, sulphonate, carboxyl, ammines, silica, silanol, phosphite esters, alkyl and hydroxyl functional groups responsible for cr(vi) removal...
متن کاملColumn biosorption of lanthanum and europium by Sargassum.
Batch and column biosorption of La(3+) (lanthanum) and Eu(3+) (europium) was studied using protonated Sargassum polycystum biomass. The ion exchange sorption mechanism was confirmed by the proportional release of protons and by the total normality of the solution, which remained constant during the process. Equilibrium isotherms were determined for the binary systems, La/H and Eu/H for a total ...
متن کاملbiosorption of cadmium by live and immobilized cells of spirulina platensis
spirulina platensis, a cyanobacterium of economic important was studied for the tolerance to cadmium. the bioassay studies showed the ec50 value to be 1.53 mg/g. the cyanobacterium was very sensitive to low metal concentration and the productivity was also reduced. the chlorophyll pigments reduced with decreasing the algal biomass. the algal survival rate showed a marked reduction in their surv...
متن کاملBIOSORPTION STUDY OF Ni AND Cr BY Sargassum filipendula: KINETICS AND EQUILIBRIUM
In this work, the biosorption of Cr and Ni by Sargassum filipendula pre-treated with CaCl2 was studied. Kinetic and equilibrium experiments were carried out for monoand multi-component solutions in a batch reactor at pH 3.0 and 30 oC. The results from the kinetic experiments showed that Cr adsorbs slower than Ni. This behavior was explained by means of a mechanistic analysis, which showed that ...
متن کاملKinetics and Equilibrium Studies on Biosorption of Chromium (VI) By Mixed Biosorbents
Biosorption is a process, which represents a biotechnological innovation as well as a cost effective excellent tool for removing heavy metals from aqueous solutions. The kinetics and equilibrium of the biosorption of Chromium (VI) from aqueous solution were investigated using immobilized mixed biosorbents of Annona squamosa seeds and Aspergillus niger in a batch system. The biosorption characte...
