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.

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...
Case study - Successful remediation of MTBE-impacted groundwater using in situ
Description Initially an SVE/bioventing system was operated for 16 months, removing over 20,800 pounds of gasoline, leaving groundwater concentrations of TPHg and benzene of 60 and 0.37 ppb, respectively. The highest MTBE concentration in September 2001 was 5,400 ppb at a monitoring well just downgradient of the former USTs, with a total estimated area above 500 ppb of over 12,000 square feet. Approximately 5.5 million gallons of groundwater were impacted. A KTI (formerly KVA) C-Sparge™ in situ chemical...
Thermally activated persulfate oxidation of NAPL chlorinated organic compounds: effect of soil ...
This study investigates the interaction of persulfate with soil components and chlorinated volatile organic compounds (CVOCs), using thermally activated persulfate oxidation in three soil types: high sand content; high clay content; and paddy field soil. The effect of soil composition on the available oxidant demand and CVOC removal rate was evaluated. Results suggest that the treatment efficiency of CVOCs in soil can be ranked as follows: cis-1,2-dichloroethene > trichloroethylene > 1,2-dichloroethane >...
