Heavy metal ions contaminate water environment through point sources and nonpoint sources. are categorized as inorganic contaminants by both the WHO USEPA. The heavy increasingly being introduced into pollutants resulting from human activities. Magnetic particles for treatment applications have received considerable attention researchers due to high separation efficiency. magnetic behave simila...

Cadmium and lead are highly toxic metals. People are exposed to them primarily through food and water. Available conventional methods (precipitation, flocculation, ion exchange, and membrane filtration) for removal of these metals from water at low concentrations are claimed to be expensive and inefficient. Different microbes have been proposed to be an efficient and economical alternative in h...

presence of heavy metals in the aquatic systems has become a serious problem. as a result, therehas been a great deal of attention given to new technologies for removal of heavy metal ions from contaminated waters. adsorption is one of the effective methods for removal of toxic heavy metal such as chromium (vi). in the present study, adsorbent is prepared from rice husk, a low cost by product f...

aims: municipal landfill leachate contains high concentrations of heavy metals, organics, ammonia . t he efficeincy of electrochemically removal of heavy metals from landfill leachate was studied. materials & methods: the leachate was obtained from kahrizak landfill in south of tehran. the experiments were carried out by batch process. the 2liter batch reactor was made of glass. there were eigh...

Heavy metals released into the surface and ground water has been a major preoccupation for many years because of their increased discharge, acute toxicity, non-biodegradable nature and tendency for bioaccumulation [1-3]. Iron a common contaminant enters the water bodies through effluents of industries such as electroplating, mining, steel processing etc. The presence of Fe (II) in water results...

Background: Industrial development has caused the release of various pollutants including heavy metals into the environment. These toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. The aim of the pre...

Diverse industrial wastes have aggravated the problem of water pollution. This problem becomes complex because of the non-degradability of inorganic pollutants like heavy metals. Metals have received particular attention among other non-degradable toxic chemicals because of their adverse effects on aquatic life forms. To control water pollution, the immediate problems have to be solved by adopt...
