One of the techniques for the removal of Cu 2+ from water and wastewaters is adsorption
and special attention has been focused on biosorption. Compared to the conventional …

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 …

Water is an essential compound for supporting the biota on earth. There are various sources
of water to support the life in freshwater ecosystems. Freshwater ecosystems play magical …

Bagasse fly ash (BFA, a sugar industrial waste) was used as low-cost adsorbent for the
uptake of arsenate and arsenite species from water. The optimum conditions for the removal …

In the second part of this series of studies, the monocomponent adsorption of Cu 2+, Co 2+
and Ni 2+ onto STA adsorbent in a fixed-bed column was investigated and optimized using …

In this study, microwave rapid synthesized NaA (NaA mw) was used to adsorb a methylene
blue (MB) from an aqueous solution. The adsorption was optimized under four independent …

Citric acid coated magnetite nanoparticles (Fe 3 O 4-Cit) have been synthesized for the
removal of cadmium from aqueous solutions. As-prepared Fe 3 O 4-Cit was characterized by …

Metal recovery from electroplating wastewater presents a promising alternative approach for
Cu/Ni resource procurement, alleviating traditional mineral mining shortages. This article …

In this work the tannic acid adsorption efficiencies for fly ash (FA), NaOH treated fly ash
(NaFA) and Chitosan modified NaOH treated fly ash (Chitosan/NaOH/fly ash composite) …

Due to commercial membranes are costly and the energy required to operate them is high,
there is an urgent need to develop alternative technologies based on earth's crust abundant …
