چکیده
Many of the current strategies for removing pollutants from water are based on nanomaterials and nanotechnology. Lower values Biological Oxygen Demand (BOD5) Chemical (COD) in results reduction amount oxidizable pollutants. We present a study COD BOD5 Wadi El Bey River (Tunisia), using magnetite nanoparticles (MNPs) magnetic fields. The removal reached higher than 50% after 60 min, with optimum efficiency at pH ≈8 MNPs concentrations 1 g/L. use permanent field (0.33 T) showed an increase 61% to 76% 63% 78%, respectively. This enhancement is discussed terms coagulation induced by adsorption ionic species onto surface due Fe3O4 affinity.

REMOVAL OF Cr (VI) FROM WASTE WATER USING NiO NANOPARTICLES
The synthesis of NiO nanoparticles was done by sol-gel method. Nickel Acetate Tetrahydrate ((CH3COO)2 –Ni·4H2O) was dissolved in ethanol with constant stirring to obtain a clear and light greenish sol. Oxalic acid solution was used to obtain a thick green gel, then dried in an oven to get dried gel and was then grinded into fine powders and calcined for different time periods to obtain nanocrys...
متن کاملVanadium Removal from Fuel Oil and Waste Water in Power Plant Using Humic Acid Coated Magnetic Nanoparticles
A method for treating fuel oil and waste water of power plant is suggested which is including vanadium elimination through contacting with humic acid coated magnetic nano-adsorbent. The nano-adsorbent was modified with humic acid (HA) as a compound having carboxyl, hydroxyl and amin functional groups. HA/Fe3O4 nanoparticles were prepared by a co-precipitation procedure and were character...

Background & objectives: The import of heavy metals into various sources of drinking water supply is one of the major problems of water quality, especially in industrial areas. The aim of this study was to investigate the ability of mercury and arsenic metal pollutants to be removed from aqueous solutions using green oxide nanoparticles synthesized by green method. For this purpose, the extract...
متن کاملAssessment of water quality in Blinaja River Basin (Kosovo) using the Canadian Water Quality Index (WQI)
Kosovo has limited natural water resources which should be well managed. This is recently realised through quantitative and qualitative monitoring of both surface and groundwater and by characterizing their quality according to their destination. In this paper, the Water Quality Index (WQI) developed by the Canadian Council of Environment Ministers (CCME WQI) was applied to evaluate the groundw...
