Adsorption of heavy metal ions to floc-type biosorbents.
Adsorption of cadmium and lead ions to floc-type biosorbents was reported in this work. Two types of biosorbents containing a marine microalga, Heterosigma akashiwo (Hada) Hada, or a purple non-sulfur bacterium, Rhodobacter sphaeroides, were prepared. The micro-organisms inactivated by steam sterilization were immobilized in casein floc and cross-linked with glutaraldehyde. In the present immob...
متن کاملAdsorption–desorption of heavy metal ions
Adsorption and desorption studies on different types of adsorbents, including natural materials such as teak tree bark powder, rice husk, natural bentonite, different algae like Ecklonia maxima, Escherichia coli, Ascophyllum nodasum, Rhizopus nigricans, Cladophora fascicularis, goethite and soils of three nuclear power plant and artificial materials such as Fe oxide-coated sand, goethite pretre...
متن کاملAdsorption Characteristics of Tannin for Heavy Metal Ions
Tannins gel was investigated as an adsorbent for heavy metal ions, such as lead, cadmium, copper, and others. The gel used in the present work was made by Mitsubishi Nuclear Fuel Co. Ltd. (MNF). It was found that the gel showed high adsorption capacity of heavy metal ions and the adsorption isotherms were correlated well by the Langmuir equation. The maximum adsorption capacity was influenced b...
متن کاملAdsorption of copper ions onto microwave stabilized heavy metal sludge.
Microwave stabilized heavy metal sludge was used as an adsorbent to remove the copper ions from aqueous solution. The adsorption characteristics of copper on the stabilized-sludge were studied by various models, such as Freundlich and Langmuir isotherm equation. Results show that the pH(zpc) of stabilized-sludge was at 9.2-9.5. Moreover, the adsorption of copper ions onto the stabilized-sludge ...
متن کاملProduction of Biosorbents from Agricultural by-product and theirs Adsorption Characteristics for Metal ions
The project concerns to adsorptive elimination of heavy metal ions from aqueous solution, namely to synthesis, modifying, studying of properties and to application combined biosorbents on the base of materials from agricultural by products. The main purpose is preparation of effective biosorbents for elimination of heavy metals ions from aqueous systems. The potential to remove metal ions from ...
