Biosorption of Copper Cu (II) in aqueous solution by chemically modified crushed marine algae (Bifurcaria bif

Biosorption of Cd(II) and Ni(II) Ions From Aqueous Solution by Raw and Pre-Treated Cystoseira Indica Algae

Biosorption of copper(II) and zinc(II) from aqueous solution by Pseudomonas putida CZ1.

To study Pseudomonas putida CZ1, having high tolerance to copper and zinc on the removal of toxic metals from aqueous solutions, the biosorption of Cu(II) and Zn(II) by living and nonliving P. putida CZ1 were studied as functions of reaction time, initial pH of the solution and metal concentration. It was found that the optimum pH for Zn(II) removal by living and nonliving cells was 5.0, while ...

Biosorption of Cu(II) Ions from Aqueous Solution by Red Alga (Palmaria Palmata) and Beer Draff

In this study, the ability of red alga (Palmaria palmata) and beer draff (brewery waste) for Cu(II) removal was investigated. The influence of factors, such as pH, initial copper concentrations, and contact time, were also studied. Results showed the adsorption process was strongly dependent on the pH value and initial concentration. The optimum pH value was in the range of 5-6. The Langmuir is...

Chemical modified bark for Cu (II) sorption from aqueous solution

In present study the removal of Copper ions from aqueous solution containing 100-800 mg/lit, using chemically modified Acacia bark was performed on laboratory scale. The chemical modification was done by treating grinded bark with formaldehyde in acidic medium. The Cu (II) is exchanged against protons on the modified bark that contain carboxyl groups in both pectin and tannin compounds. The eff...

Biosorption of copper from aqueous solution using algal biomass

Sorption experiments using the dead biomass of Spirogyra species, for copper removal were carried out to study the influence and optimization of the biosorption of Cu (II). The effect of pH (1.0 10.0), initial metal ion concentration (1 100ppm), different contact periods (30 180 min), varying temperature (25 – 50 oC) and varying biomass quantities (0.5,1.0,1.5 and 2.0 g) were also examined. It ...
