Removal of Heavy Metals from Aqueous Solution by Mordenite Nanocrystals
This study examined the ability of the synthetic mordenite nanocrystal to remove Tl(III) and As(III) from an aqueous solution. The determination of the concentration changes of H+ and OH- quantities in the acidic (pH 3) and alkali (pH 9) treated mordenite nanocrystals were done by the potentiometric titration curves. The maximum uptake capacities (Qmax) of these metal ions using the mordenite i...
متن کاملRemoval of Heavy Metals and Patho- Gens during Biphasic Fermentation of Solid Wastes
Research was conducted to study the effects of biphasic anaerobic fermentation upon an organic fraction of municipal solid waste, and to observe the fate of heavy metals and pathogenic organisms in the acidogenic and methanogenic environments of the biphasic process. The high-solids (16 wt % solids) substrate was packed in a bench-scale, anaerobic, solid-state fermenter with amounts of lead nit...
متن کاملRemoval of Heavy Metals from Wastewater Using Cow Bone Charcoal
Bone charcoal, a mixed adsorbent containing around 10% carbon and 90% calcium phosphate, is mainly produced by thermal treatment of bones. Structurally, calcium phosphate in bone charcoal is in the hydroxyapatite form [1-2]. Traditionally, bone charcoal has been used to remove color in sugar solutions in the sugar refining industry. Recent studies use bone charcoal to adsorb radioisotopes of an...
متن کاملRemoval of Heavy Metals from Waste Water Using Water Hyacinth
-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...
متن کاملRemoval of heavy metals from aqueous solution by sawdust adsorption.
The adsorption of lead, cadmium and nicel from aqueous solution by sawdust of walnut was investigated. The effect of contact time, initial metal ion concentration and temperature on metal ions removal has been studied. The equilibrium time was found to be of the order of 60 min. Kinetics fit pseudo first-order, second-order and intraparticle diffusion models, hence adsorption rate constants wer...
