Sargassum seaweed as biosorbent for heavy metals

Bioremediation of Waters Contaminated with Heavy Metals Using Moringa oleifera Seeds as Biosorbent

Use of natural products as biosorbent of heavy metals ó An overview

Industrial effluents loaded with heavy metals are a cause of hazards to human and other forms of life. Conventional methods such as precipitation, evaporation, electroplating, ion exchange, membrane processes, etc. used for removal of heavy metals from waste water however, are often cost prohibitive having inadequate efficiencies at low metal ion concentrations. Biosorption can be considered as...

Heavy metals removal in aqueous environments using bark as a biosorbent

Tree bark is among the widely available and low-cost sorbents for metal adsorption in aqueous environments. A state-of-the-art review is compiled carrying out a comprehensive literature search on the biosorption of heavy metals in solution onto different bark species, including a characterization of bark structure and chemistry. The results indicate that biosorption has been gaining importance ...

Scavenging of Heavy Metals from Particulates by Brown Seaweed

Concentrations of Cu, As, Pb, Zn and Ag (but not Cd, Co, Fe, Mn and Hg) in the tissues of benthic algae (Fucus vesiculosus) correlate significantly with concentrations in sediment. Metals which complex most strongly with algal tissues show the strongest correlations of algal tissue and sediment. Scavenging these metals from particulates may be an important source of uptake by the algae. If so, ...

Low cost biosorbent banana peel (Musa sapientum) for the removal of heavy metals

The efficacy of the banana peel (Musa sapientum) biomass was tested for the removal of lead, copper, zinc and nickel metal ions using batch experiments in single and binary metal solution under controlled experimental conditions. It is found that metal sorption increases when the equilibrium metal concentration rises. At highest experimental solution concentration used (150 mg/L), the removal o...
