Study regarding the sorption of erythrosine from aqueous solution onto soil
Environmental Engineering and Management Journal › Vol. 8 › Nr. 6 Abstract
In this paper, the capacity of a soil to retain the dye Erythrosine B from aqueous solution by sorption has been studied. Batch adsorption experiments were conducted to investigate the sorption of the dye from aqueous solutions onto soil with particles of different size. Different models were used to describe the kinetic data, to calculate the corresponding rate constants and to predict the theoretical capacities of soil for dye sorption.

Studies on sorption and transport processes of cadmium in soils
Environmental Engineering and Management Journal › Vol. 8 › Nr. 6 Abstract
Heavy metals produced and released by anthropogenic activities generate serious environmental problems. Ions of toxic metals can bind to the mineral surface in a number of ways, including absorption, adsorption, precipitation, ion exchange.
The paper shows that the fate and migration of heavy metals in soils strongly depend on the physical properties and chemical and mineralogical composition of such environments. Cadmium is one of the most toxic metals with carcinogenic and teratog...

After curing the mixture samples for 1, 7 and 28 days at a working room temperature of +21°C, they were subjected to the freeze-thaw test at -21°C, +21°C fo...

ECO-FRIENDLY SYNTHESIS OF SILVER NANOPARTRICLES USING Gazania rigens AND EVALUATION OF ACTIVITIES
Environmental Engineering and Management Journal › Vol. 20 › Nr. 1 The present study describes the facile synthesis of silver nanoparticles (AgNPs) by green method using aqueous extract of Gazania rigens. The size, morphological, compositional and optical properties of silver nanoparticles were examined through X-ray diffraction (XRD), Energy Dispersive X-ray spectroscopy (EDX), Scanning Electron Microscope (SEM), and UV-Vis spectroscopy respectively. Ultraviolet-Visible spectra showed the absorbance band between 425–460 nm which indicated the synthesis o... Autori: Tayyaba Shahzadi ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28349 |
