Dispersion of C(60) in natural water and removal by conventional drinking water treatment processes.
The first objective of this study is to examine the fate of C(60) under two disposal scenarios through which pristine C(60) is introduced to water containing natural organic matter (NOM). A method based on liquid-liquid extraction and HPLC to quantify nC(60) in water containing NOM was also developed. When pristine C(60) was added to water either in the form of dry C(60) or in organic solvent, ...
متن کاملCitrate Stabilized Silver Nanoparticles: Study of Crystallography and Surface Properties
Citrate stabilized silver (Ag) colloidal solution were synthesized and characterized for crystallographic and surface properties by using transmission electron microscopy (TEM) and zeta potential measurement techniques. TEM investigation depicted the size of Ago ranges from 5 to 50 nm with smaller particles having single crystal structure while larger particles with structural defects (such as ...
متن کاملImpact of Raw Water Ammonia on the Surface Water Treatment Processes and Its Removal by Nitrification
In Dhaka City, Dhaka Water Supply and Sewerage Authority (DWASA) supply drinking water and provides sanitation services since 1963 to the city dwellers. About 10 million people depend on the supply of drinking water and sanitation services provided by DWASA. At present DWASA is dependent more on the surface water than the under ground water because of over extraction of ground water2. Every yea...
متن کاملPresence of nanoparticles in wash water from conventional silver and nano-silver textiles.
Questions about how to regulate nanoenhanced products regularly arise as researchers determine possible nanoparticle transformation(s). Focusing concern on the incorporation and subsequent release of nano-Ag in fabrics often overshadows the fact that many "conventional silver" antimicrobials such as ionic silver, AgCl, metallic Ag, and other forms will also form different species of silver. In ...
متن کاملEffects of silver nanoparticles on biological nitrogen removal processes.
The effects of silver (Ag) nanoparticles (NPs) on activated sludge in a biological nitrogen removal (BNR) process were investigated under aerobic and anoxic conditions. We show that nitrification was more vulnerable to Ag NPs exposure than denitrification at the same Ag NPs concentration. In continuous operation of the BNR process, a higher inhibitory effect on nitrification was attributed to a...
