Thesis on biosorption of heavy metals

We can see that the Raw-seeds have an acidic surface. Optimization of conditions and adsorption isotherm studies of orange TGU on low cost carbon systems, Indian Journal of Environmental protection, 23 Dean, Cadmium accumulation by a citrobacter sp.

Adsorption of Hg II ions from water by Activated carbons. The uptake of a compound is affected by plant species characteristic [ 44 ].

According to the experimental data, the HCl-seeds had an important amount of acidic groups than Raw-seeds followed by NaOH-seeds. The utilization of cellulose dye adsorption on. In the case of alkali pre-treatment, bioadsorption capacity of Mucor rouxii biomass was significantly enhanced in comparison with autoclaving Yan and Viraraghavan, AAS survey revealed that in instance of Cadmium Cd ,5 samples holding contents between 0.

Srinivasan K and Saravanan S, Kinetic studies on adsorption of Methylene blue onto Lignite fly ash, Journal of Industrial pollution Control, 19 2: Biosorption of heavy metals using dried algal biomass has been extensively described.

Indian Journal of Environmental protection, 23 Removal of lead II ions by adsorption onto bambodust and commercial activated carbons —A comparative study Electronic J. Fourest and Roux, invalidated this hypothesis attributing the responsibility of the specific uptake decrease to metal concentration shortage in solution.

The desorption process should: Readers —Generating awareness of the readers about the prevalence and increasing concern for heavy metal contamination of Philippine waters. K and Rao, A. Renugadevi, N, Kavitha, B and Sangeetha, M,Removal of Methylene blue using a low cost activated carbon from Cassia siamea by adsorption technique, Indian Journal of Environmental protection, 30 1: Current world Environment, 3 1: The waste water from industries like, metal plating, mining operations, tanneries, chloralkali and radiator manufacturing, smelting, alloy industries, textile industry, dye industries effluents need the treatment.

Varsha and Aditistated that, white rot fungi Trametes Versicolor was used to remove Reactive black 5 as carbon source glucose. To determine the oxygenated groups content, back titrations of the filtrate 10 mL were achieved with standard 0. Strong biosorbent behaviour of certain micro-organisms towards metallic ions is a function of the chemical make-up of the microbial cells.

The biosorbents having greater surface acid groups have higher cation exchange properties. N and Clines, This was plotted in a conc. R and Patil, P. Activated carbons are widely used as adsorbents in wastewater treatment because of their high surface areas and active functional groups, but their high cost inhibits sometimes their use [ 13 ].

The biosorption mechanisms are various and are not fully understood. The process continues till equilibrium is established between the amount of solid-bound sorbate species and its portion remaining in the solution. Inversely, for pH superior of 5. Kinetics of Adsorption of Dyes on activated carbon: Sivamani S and Prince Immanuel V, The main disadvantage of this process is the generation of sludge.

YUNUS PAMUKOĞLU under supervision of PROF. DR. FİKRET KARGI and we certify that in our opinion it is fully adequate, in scope and in quality, as a thesis for the degree of Doctor of Philosophy.

The common filamentous fungi can sorb heavy metals (Zn, Cd, Pb, Fe, Ni, Ag, Th, Ra & U) from aqueous solutions to varying extents. Fungal biosorption largely depends on parameters such as pH, metal ion and biomass concentration. Phd Thesis On Biosorption Of Heavy Metals phd thesis on biosorption of heavy metals III.
