CdS nanocrystalline materials have been prepared by reaction of Cd(II) ions with an alkaline solution of thiocarbamide in the aqueous solution phase. The effect of reaction time and surfactants (cetyltrimethyl ammonium bromide (CTAB), sodium dodecyl sulfate (SDS)) on morphology and size of the products has been investigated. Dramatic shape and size variations have been observed by varying the surfactant and reaction time. CdS nanocrystals formed in various reactions were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM) to determine the crystallinity, phase, composition, size, and morphology. The optical properties of the thus prepared samples were determined by UV-vis absorption spectra. A possible formation mechanism of CdS nanocrystals has also been discussed in this article. © 2011 American Chemical Society.

The present study reports the influence of different factors on the sorption of Pb and Cd by Nostoc muscorum. The results showed that extent of Pb and Cd removal by N. muscorum cells increased with increasing biosorbent dose, but exhibited decline in the adsorption capacity. The maximum sorption of Cd (85.2%) and Pb (93.3%) was achieved at 60 and 80 microg/ml concentrations of respective metal, within 30 and 15 min, respectively. The result revealed that optimum biosorption of Pb and Cd occurred at pH 5 and 6, respectively, at 40 degrees C temperature. Presence of binary metals (both Pb and Cd) in a solution showed that the presence of one metal ion resulted into decreased sorption of other metal ion. The presence of Ca and EDTA showed significant decrease in the sorption of Pb and Cd, while other anions and cations did not show significant effect on the biosorption of both the metals. Maximum desorption of Pb and Cd was achieved in the presence of EDTA and HNO3, respectively. Results also showed that the test biosorbent could be repeatedly used up to six biosorption/desorption cycles without significant loss of its initial metal adsorption capacity.

An increasing area of fly ash (FA) disposal and its toxicity have become a global concern due to the proliferation of coal-fired power plants, which contaminate the ecosystems of our earth. In this regard, many plants are suggested for phytoremediation of FA disposal sites, but there is a dearth of studies regarding commercial crop-based phytoremediation having a range of economic and ecological services. Therefore, the present investigation was focused to examine phytoremediation potential of naturally grown industrial crop Ricinus communis L. on FA polluted sites. The bioconcentration factor value of all metals in the root of R. communis L. was greater than 1 which indicates the metal accumulation potential of this crop. Translocation factor value of all the metals was found less than 1, which shows that these metals are stabilized in the root part of the plant. Furthermore, being industrial oil yielding crop and unpalatable, R. communis L. is a potential candidate for FA phytoremediation along with its economic and ecological values. Thus, R. communis L. can be used as a commercial crop for phytostabilization and revegetation of FA disposal sites in tropical and sub-tropical region. Besides the stabilization of heavy metals, FA revegetation provides other hidden benefits such as carbon sequestration, substrate quality enhancement, esthetically pleasant landscape, multipurpose oilseed production and biodiversity conservation. © 2013 Elsevier B.V.

Renewable and Sustainable Energy Reviews | Year: 2012
Biomass is indirect source of solar energy and it is renewable in nature. It is one of the most important energy source in near future because of its extensive spread availability and promising potential to reduce global warming. Thermo chemical conversion of biomass yield variety of solid, liquid and gaseous fuels and have equal importance both at industrial and ecological point of views. Present review gives holistic view of various thermo-chemical conversion route of biomass. Gasification technology, pyrolysis options and scope of potential by product from there routes like hydrogen and charcoal production comprehensively reviewed with present context. © 2012 Elsevier Ltd.

The present investigation was focused to examine the phytoremediation potential of naturally grown Ipomoea carnea on fly ash (FA) deposits. I. carnea is an invasive species and mostly neglected by people but it has unusual characteristics which deals to phytoremediation. The metal accumulation of Cd, Pb, Cu, Cr, Mn and Ni ranged from 5.3 to 39.7, 7.4 to 30.6, 19.9 to 32.5, 9.5 to 20.6, 19.0 to 90.1, and 13.7 to 68.2μgg-1, respectively, in all the parts of I. carnea grown on barren FA deposits during two periods (pre- and post-monsoon). The bioconcentration factor (BCF) values of Cd, Pb, Mn, and Ni in root and stem were greater than 1 during both periods which indicates the metal accumulation potential of I. carnea. There is a dearth of study recommending the safe and effective green technology for the phytoremediation of FA dumps. In this regards, I. carnea was identified as an effective plant for phytoremediation in harsh environmental conditions of abandoned FA deposits. © 2012 Elsevier B.V.
