Adsorption of methylene blue and methyl red dyes from aqueous solutions onto modified zeolites
(2013)Zeolite, hematite, modified zeolite and commercial activated charcoal were examined for their ability to remove methylene blue (MB) and methyl red (MR) from their aqueous solutions. Modified zeolite and hematite were ... -
Boron behavior in apple plants in acidic and limed soil
(2013)In dry Mediterranean-type climates boron (B) levels may naturally be high and even toxic to plants. Although liming of an acidic soil is expected to decrease B levels, it is not known what the effects would be in such areas ... -
Cu-Zn powders as potential Cr(VI) adsorbents for drinking water
(2013)This work examines the possibility of applying CuZn alloys as a reducing medium for the efficient removal of hexavalent chromium from drinking water. In an effort to develop a route for producing powders of CuZn alloys ... -
Current strategies for dairy waste management: A review
(2006)Industrial waste management is nowadays one of the main issues for ensuring a sustainable environment. Dairy waste management in particular is very crucial in view of the high organic matter and high nutrient levels contained ... -
Decolorization and degradation of reactive azo dyes via heterogeneous photocatalytic processes
(2010)Reactive dyes are extensively used in textile industry in the last years due to their superior performance, but they are environmentally hazardous and difficult to treat effectively by classical methods. In the present ... -
Ecosystem simulation modeling of nitrogen dynamics in the restored lake Karla in Greece
(2011)Restored lakes are complex dynamic ecosystems. Ecosystem-level modeling of the processes that take place in a lake is a useful tool for understanding lake function and structure and for making predictions. A nitrogen ... -
Fate of three insect growth regulators (IGR) insecticides (flufenoxuron, lufenuron and tebufenozide) in grapes following field application and through the wine-making process
(2011)The dissipation of three insecticide flufenoxuron, lufenuron and tebufenozide residues in grapes after field treatments and during the wine-making process was assessed. Residues were determined in grape, must, centrifuged ... -
Influence of ozonation on the in vitro mutagenic and toxic potential of secondary effluents
(2008)Reclamation of municipal effluents by advanced treatment processes is an attractive perspective for facing certain water shortage problems. However, the application of tertiary techniques should be thoroughly examined for ... -
A novel approach for arsenic adsorbents regeneration using MgO
(2014)An integrated procedure for the regeneration of iron oxy-hydroxide arsenic adsorbents by granulated MgO is proposed in this study. A continuous recirculation configuration, with a NaOH solution flowing sequentially through ... -
Phosphate Adsorption from Aqueous Solutions onto Goethite, Bentonite, and Bentonite-Goethite System
(2013)The present paper examines the phosphate adsorption from aqueous solutions onto goethite, bentonite, and bentonite-goethite system. The properties of the materials were studied by X-ray diffraction (XRD), attenuated total ... -
Stereotactic amygdalotomy in the management of severe aggressive behavioral disorders
(2008)Object. Stereotactic amygdalotomy has been utilized as a surgical treatment for severe aggressive behavioral disorders. Several clinical studies have been reported since the first description of the procedure. In the current ... -
Uptake of Zn2+ ions by a fully iron-exchanged clinoptilolite. Case study of heavily contaminated drinking water samples
(2007)Clinoptilolite, a natural zeolite, was used for the synthesis of a high surface area clinoptilolite (Clin)-iron (Fe) oxide system, in order to be used for the removal of Zn2+ ions from drinking water samples. The new system ... -
Use of Modified Zeolites for the Remediation of Waters and Cultivated Soils from Cu(II)
(2012)The ability of iron oxides (goethite) and natural zeolite (clinoptilolite) to adsorb copper from its aqueous solutions was extensively studied in the past. In this paper, the production of modified zeolites (systems I and ...
