Layered double hydroxides as potential solid for obtaining more environmentally friendly pesticides
Environmental Engineering and Management Journal › Vol. 6 › Nr. 4 AbstractThe paper describes the synthesis and characterization of layered double hydroxides (LDH) intercalated with 4,6-dinitro-o-cresol(DNOC) and 2,6-dichlorobenzonitrile (2,6DBN) by anionic exchange method. The incorporation of the organic pesticides in the structure of layered double hydroxides can offer premises to increase the pesticide active life by reducing its volatilization, controlling the release of the pesticide from the layered structure and decreasing the pesticide adsorption in s...

The nitrate concentration at this location has been above the maximum allowed concentration for several decades... Autori: Marko Ĺ rajbek ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28140
MACROSPHERICAL POROUS METALLOSILICATE MATERIALS: CHARACTERIZATION AND APPLICATIONS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 2 The main goal of this work was to develop a cheap and easy method for the synthesis of the porous metallosilicate macrospheres. Zirconium silicate macrospheres with diameters in the range 1.5 – 1.6 mm were obtained by the spray gelling technique, using the multi templating method. Tetraethyl orthosilicate was used as silica source. The chitosan played a dual role (pore and shape generating agent), while other inexpensive and easily accessible biomaterials including yeast, sugar and gelatin...

MODELING OF A RECTANGULAR CHANNEL MONOLITH REACTOR FOR SORPTION-ENHANCED WATER-GAS SHIFT
Environmental Engineering and Management Journal › Vol. 19 › Nr. 2 As CO2 concentration levels in the atmosphere are steadily reaching a point of no return, it is paramount that actions are taken towards mitigating emissions by improving the efficiency of existing processes. Sorption-enhanced water-gas shift (SEWGS) combines the water-gas shift reaction with in-situ adsorption of CO2 on potassium-promoted hydrotalcite (K-HTC). This enables a
direct conversion of syngas into separate hot streams of H2 at feed pressure and CO2 at regeneration pressure, making th... Autori: Vlad-Cristian Sandu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28149
CLAY COMPOSITE WATER FILTERS: THE CASE OF FLUORIDE, NITRITE AND Escherichia coli REMOVAL
Environmental Engineering and Management Journal › Vol. 19 › Nr. 4 Inorganic ceramic materials is receiving more attention in recent times due to their unique characteristics which include
different pore structures, hydrophilic surfaces, high chemical, thermal and mechanical stabilities that offer avenues for application
in water treatment. In the present work, cost-effective clay ceramic water filters of different designs were developed from clay (50,
60, and 70) %, sawdust (15, 20, 25, and 35) %, grog (5, 10 and 15)% ratios plus 5% bone char by volume and ... Autori: Enyew Amare Zereffa ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28196
SYNERGISTIC EFFECT OF FUEL AGENTS AND MASS RATIO FOR MORPHO-STRUCTURAL OPTIMIZATION OF MAGNETIC CLAYBASED NANOCOMPOSITES WITH HIGH ADSORPTION CAPACITY
Environmental Engineering and Management Journal › Vol. 19 › Nr. 5 The study is focused on creating magnetic mesoporous materials through the insertion of a nickel ferrite into the structure of kaolintype clay. Sol-gel auto-combustion method was employed to synthesize the materials, using glycine and tartaric acid as chelating/combustion agents. This is the first study on the combined effect of different fuel agents and of clay-to-ferrite molar ratio
on the structural, textural, magnetic and adsorptive properties of nanocomposites. The value of the average por... Autori: Stefana Cojocaru ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28210
BUILDING INFORMATION MODELING APPLICATION FOR GROUNDWATER RECHARGE: DEVELOPMENT OF MULTIPLE STRUCTURES
Environmental Engineering and Management Journal › Vol. 19 › Nr. 6 Globally the researchers are identifying the new ways for better urban sustainability. One major issue in the current world is the lack of fresh water availability in cities due to rapid increase in the population. To meet water requirement, scientist are exploring different ways to enhance the groundwater recharge capacity. One such solution is the use of building information modelling (BIM)
technology to identify multiple structures that can be constructed to provide the potential recharge. T... Autori: Ahsen Maqsoom ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28218
RESPONSES OF SHALLOW GROUNDWATER SYSTEM TO DIFFERENT WATER-SAVING PRACTICES IN TYPICAL IRRIGATION AREA IN NORTHWEST CHINA
Environmental Engineering and Management Journal › Vol. 19 › Nr. 9 The Jinghui Canal Irrigation District (JCID) is a highly productive agricultural area of Shaanxi province, China. Because of severe water scarcity, implementing water-saving renovation practices for agricultural sustainability is necessary. To determine the influence of different water saving practises on the shallow groundwater system in the JCID, ArcGIS and Processing MODFLOW are used to simulate changes in shallow groundwater in the irrigated farmland in this area. The results show that field... Autori: Fenggang Dai ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28278
APPROPRIATE SOLUTIONS FOR WASTEWATER REUSE IN AGRICULTURE: A PILOT PLANT IN RAFAH, GAZA STRIP
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Water supply represents a constant worldwide challenge for people and authorities. This issue is significantly severe in semiarid regions such as Gaza Strip, where groundwater constitutes the only fresh water source. Furthermore, Gaza Strip area suffers from
water scarcity due to the decrease in water recharge and a constantly groundwater over-pumping, along with seawater intrusion, which cause serious problems in fresh water supply. Treated wastewater reuse represents a sustainable approach to... Autori: Alessandra Bonoli ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28288
FIELD APPLICATION OF A REAGENT FOR IN SITU CHEMICAL REDUCTION AND ENHANCED REDUCTIVE DICHLORINATION TREATMENT OF AN AQUIFER CONTAMINATED WITH TETRACHLOROETHYLENE (PCE), TRICHLOROETHYLENE, 1,1-DICHLOROETHYLENE, DICHLOROPROPANE AND 1,1,2,2-TETRACHLOROETHANE
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Groundwater at an abandoned industrial area near Bergamo, Italy, was historically contaminated by tetrachloroethylene (PCE) (>100 μg/L) and, to a lesser extent, by trichlorethylene (TCE), dichloropropane (DP) and 1,1,2,2-tetrachloroethane (R-130). A
liquid reagent (EHC® Liquid) was selected for remediation of groundwater at the site. The reagent is provided in two parts: EHC® Liquid Mix (a soluble organo-iron salt), and ELS® Microemulsion (a lecithin-based carbon substrate), a...
