Biosorption and Recovery of Heavy Metals from Aqueous Solutions by Eichhornia Crassipes (water Hyacinth) Ash
Heavy metal’s release without treatment poses a significant threat to the environment. Heavy metals are non-biodegradable and persistent. In the present study the ash of water hyacinth (Eichhornia crassipes), was used to remove six metals from aqueous solutions through biosorption. Results of batch and column experiments showed excellent adsorption capacity. Removal of lead, chromium, zinc, cad...
متن کاملBiosorption of Cu2+ from aqueous solutions by pretreated Cladosporium sp.
In this paper, adsorption properties of a pretreated of Cladosporium sp. for Cu2 were studied. The fungi pretreated with some chemical reagents exhibited higher Cu2+ removal capacities than native biomass. The optimum chemical reagent was 0.2M NaOH. After 0.2M NaOH pretreatment, optimum conditions of biosorption were found to be pH 5.0, temperature 35 degrees C, and stirring speed of 100rpm. Eq...
متن کاملThe Mechanism of Chromium Biosorption by Saccharomyces Cerevisiae
The Biosorption property of S. cerevisiae for chromium uptake was investigated in an immobilized cell bioreactor. Saw dust was utilized as the solid bed in the reactor. Adsorption of S. cerevisiae on saw dust obeys a first order reaction kinetic up to 6 hours. The immobilized biomass particles are porous and exist in the new generation of biological adsorbent. Chromium biosorption was studied i...
متن کاملThe mechanism of thorium biosorption by Rhizopus arrhizus.
Inactive cells of Rhizopus arrhizus have been documented to exhibit a high thorium biosorptive uptake (170 mg/g) from aqueous solutions. The mechanism of thorium sequestering by this biomass type was investigated following the same method as for the uranium biosorption mechanism. The thorium sequestering mechanism appeared somewhat different from that of uranium. Experimental evidence is presen...
متن کاملBiosorption of Cd2+ and Cu2+ from aqueous solution using Gracilaria corticata waste biomass
Pollution of aquatic environments by toxic trace metals has been taking place because of discharge of untreated effluents from many industrial processes. Conventional methods used for removing dissolved heavy metal ions from wastewaters have significant disadvantages including incomplete metal removal, requirements for expensive equipment, high energy requirements and generation of toxic sludge...
