To ease the adsorbent recovery and to increase the adsorption capacity of polyaniline (PANI), aniline was polymerized in the presence of a solvothermally prepared nano-composite of reduced graphene oxide and Fe3O4 (RGO/Fe3O4). The polyaniline was formed along the RGO/Fe3O4 composite in transmission electron microscope (TEM). The thus formed PANI/RGO/Fe3O4 adsorbent was tested and applied in removing Hg(II) in aqueous solution. The initial adsorption rate as well as the adsorption capacity increases with the incorporation of RGO/Fe3O4. The magnetic separation of PANI/RGO/Fe3O4 was easy, and its regeneration can be carried out at the optimal pH of 2. Test results proved the competence of the prepared adsorbent in pollution remediation applications for safer water quality and environmental protection.

Environmental IssuesControlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology.In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes referred to as multi or dual phase extraction (MPE or DPE) — has further complicated the design requirements for safely applying...
Electricity generation through a photo sediment microbial fuel cell using algae at the cathode
Sediment microbial fuel cells (SMFCs) are bio-electrochemical devices generating electricity from redox gradients occurring across the sediment–water interface. Sediment microbial carbon-capture cell (SMCC), a modified SMFC, uses algae grown in the overlying water of sediment and is considered as a promising system for power generation along with algal cultivation. In this study, the performance of SMCC and SMFC was evaluated in terms of power generation, dissolved oxygen variations, sediment organic matter...

Improving Groundwater with Chemical Treatments
Groundwater contributes to the health and well-being of a natural environment in the area and those systems connected to it. There are times that contaminants create an imbalance in groundwater, and a groundwater treatment system needs to be applied. Here are some chemical treatments that work to help treat groundwater. The Basics of Groundwater Remediation For the health of an environment and surrounding organisms, or for the sake of converting groundwater for other uses, groundwater remediation is a useful...
