Removal of hexavalent Cr by coconut coir and derived chars--the effect of surface functionality.
TLDR
To develop a cost-effective method for removing Cr(VI) from water, the original CC is more advantageous than the carbonaceous counterparts because no pyrolysis is required for the application and CC has a higher content of functional groups for reducing Cr( VI) to less toxic Cr(III). Expand
Reduction of Cr(VI) by crop-residue-derived black carbon.
TLDR
The results suggest that BC derived from burning crop residue is an effective reductant for Cr(VI) and may play an important role in determining the fate of Cr( VI) in BC-rich farmland soils. Expand
Removal of hexavalent chromium from acidic aqueous solutions using rice straw-derived carbon.
TLDR
The results suggest that rice straw-based carbon may be effectively used at low pH as a substitute for activated carbon for the treatment of Cr(VI) contaminated water. Expand
Air Pollution and Control in Different Areas of China
Air pollution resulting from the combustion of fossil fuel is an environmental topic receiving global attention. In China, rapid economic development followed the economic reforms of 1978, especiallyExpand
Arsenate adsorption from water using a novel fabricated copper ferrite
Abstract A novel fabricated copper ferrite was investigated for its As(V) removal in this study. The adsorption of As(V) by this recycled copper ferrite exhibited an L-shaped nonlinear isotherm,Expand
Arsenate adsorption by Mg/Al-NO3 layered double hydroxides with varying the Mg/Al ratio
Abstract Arsenate is one of the main contaminants threatening water supplies all over the world. Layered double hydroxides (LDHs) have large surface areas and high anion exchange capacities, so theyExpand
Photocatalytic reduction of Cr(VI) in the presence of NO3- and Cl- electrolytes as influenced by Fe(III).
TLDR
Under the acidic conditions that are favorable for Fe-Cl complex formation or in the presence of NO3-, the effects of inorganic components on Cr(VI) photoreduction cannot be ignored for the precise evaluation of the transformation of Cr in the environment. Expand
β-cyclodextrin functionalized graphene oxide: an efficient and recyclable adsorbent for the removal of dye pollutants
AbstractA novel method for the preparation of β-cyclodextrin grafted graphene oxide (GO-β-CD) has been developed. The GO-β-CD was characterized by Fourier transform infrared spectroscopy, 13C NMRExpand
A mechanism study of light-induced Cr(VI) reduction in an acidic solution.
TLDR
The kinetic result of each photo-reduction reaction pathway shows zero-order kinetics, suggesting that the photolysis reaction of H(2)O or FeCl(2+) is the rate-determining step in each pathway. Expand
Effects of rice straw ash amendment on Cu solubility and distribution in flooded rice paddy soils.
TLDR
The results suggest that the RSA can retard the bioavailability and movement of the metal in contaminated soils and, thus, lower the potential environmental risk of Cu toxicity. Expand
