Equilibrium and Kinetic Studies of Cd2+ Biosorption by the Brown Algae Sargassum fusiforme

A fundamental investigation of the biosorption of Cd2+ from aqueous solution by the edible seaweed Sargassum fusiforme was performed under batch conditions. The influences of experimental parameters, such as the initial pH, sorption time, temperature, and initial Cd2+ concentration, on Cd2+ uptake by S. fusiforme were evaluated. The results indicated that the biosorption of Cd2+ depended on the...

Studies on Biosorption of Nickel Using Immobilized Fungus, Rhizomucor Tauricus

Rhizomucor tauricus, an industrial fungus, was immobilized in sodium alginate and used as adsorbent for the removal of nickel from aqueous solutions. The biosorption capacity of Ni(II) was found to be 394 mg/g of immobilized biomass. It was observed that an increase in pH from 3 to 6 increased the percent adsorption, and an increase in liquid-to-solid ratio from 2 to 10 increased the metal upta...

Electron Microscope Studies on Blue-green Algae

Several species of blue-green algae were studied in thin sections with the electron microscope. Our electron micrographs confirm the view that the cell of blue-green algae is different and simpler in organization than the typical plant or animal cell. On the other hand, the general pattern of ultrastructure is the same as that found in bacteria and Streptomyces. The cell boundary is formed by a...

Biosorption of Zinc on to Gracilaria Corticata (Red Algae) Powder and Optimization using Central Composite Design

This paper presents the biosorption of zinc from aqueous solutions using Gracilaria corticata (red algae) powder as a biosorbent. The equilibrium studies on biosorption of Zinc are carried out in batch process. The extent of removal depends on initial concentration of Zinc ion, pH, dosage, temperature etc. The optimum dosage is 15 g/L at the equilibrium agitation time of 60 min. The % biosorpti...
