Removal of cadmium from aqueous solution using marine green algae, Ulva lactuca

removal of lead and cadmium ions from aqueous solutions using dried marine green macroalga (caulerpa racemosa)

in this study caulerpa racemosa has been characterized and used for the removal of cd(ii) and pb (ii) from aqueous solutions. the effect of ph, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. langmuir and freundlich models were applied to describe the biosorption isotherm of the metal ions by c. racemosa biomass. the adsorption data can be ...

REMOVAL OF CADMIUM FROM AQUEOUS SOLUTION USING COBALTSILICATEPRECIPITATIONTUBE (CoSPT) ASADSORBENT

Cobalt silicate precipitation tube (CoSPT), prepared through ‘silica garden’ route was found to be a potential adsorbent for removal of cadmium from aqueous medium. Detail adsorption study of Cd(II) on CoSPT was investigated. Batch adsorption studies were carried out as a function of contact time, adsorbent dose, adsorbate concentration (50-300 mg L-1), temperature (298-323K). Cd(II) loading on...

Cadmium removal from aqueous solution by green synthesis iron oxide nanoparticles with tangerine peel extract.

BACKGROUND The adsorption process by metal oxide nanoparticles has been investigated an effective agent for removing organic and inorganic contaminants from water and wastewater. In this study, iron oxide nanoparticles were synthesized in the presence of tangerine peel extract as adsorbent for cadmium ions removal from contaminated solution. Iron oxide nanoparticles prepared by co-precipitation...

Removal of Malachite Green dye from aqueous solution using MnFe2O4/Al2O3 Nanophotocatalyst by UV/H2O2 process

Background & Aims of the Study: Malachite Green (MG) is the most commonly used substance for dying cotton, food & pharmacy industries, paper, leather and silk. On inhalation it can cause difficult breathing, while on the direct contact it may cause permanent injury of the eyes of human and animals, burning sensations, nausea, vomiting, profuse sweating, mental confusion and met...
