 Background: The primary coolant is an essential cooling medium used to control heat in a nuclear power plant. During the oxidation process, Nickel may be released in the primary coolant which increases its contamination. The operational problems and high cost of treatment necessitate the research for some newer methods. The aim of this research is investigation of nickel removal from synthetic...

Iron in groundwater is one of the problems that render the water unsuitable for drinking. The concentration above 0.3 mg/L is common in groundwater. The conventional method of removal is by precipitation under oxic condition. In this study, iron removal under anaerobic conditions was examined by batch experiment as a main purpose. The process involved by purging of groundwater samples with H2S ...

Great attention should be paid now to simultaneously removing common pollutants, especially inorganic pollutants such as nitrate and heavy metals, as individual removal has been investigated extensively. Removing common pollutants simultaneously by iron metal is a very effective alternative method. Near neutral pH, heavy metals, such as copper and nickel, can be removed rapidly by iron metal, w...
