Water polluted with heavy-metal ion has been a major problem in recent years. Among
various metal ions, nickel (II) is a priority pollutant commonly found in industrial wastewater …

Among various methods adsorption can be efficiently employed for the treatment of heavy
metal ions contaminated wastewater. In this context the authors reviewed variety of …

The presence of cobalt (II) in wastewater is an emergent concern because of its toxicity at
elevated concentration. Co (II) is a non-biodegradable, carcinogenic and mutagenic …

The use of low-cost adsorbents was investigated as a replacement for current costly
methods of removing metals from aqueous solution. Removal of copper (II) from aqueous …

Adsorption of Ni (II) onto blue-green marine algae (BGMA) is investigated under batch
condition. Under optimum experimental conditions, the initial Ni (II) metal ion concentration …

The presence of nickel in aquatic systems due to discharge of industrial effluents is of
concern because of its toxic and nonbiodegradable nature. Its removal from water and …

Heavy metal is released from many industries into water. Before the industrial wastewater is
discharged, the contamination level should be reduced to meet the recommended level as …

Present study deals with the development of a nano-porous adsorbent using neem bark for
the simultaneous removal of Cu (II), Cr (VI) and Zn (II). The developed adsorbent is …

The effects of varying operating conditions on metals removal from aqueous solution using a
novel nano-size composite adsorbent are reported in this paper. Characterization of the …

Heavy metal pollution has become one of the most severe environmental issues. Adsorption
is an effective method for removing heavy metals from aquatic environments. The adsorption …
