(Amer Chemical Soc, Washington, 2018)
The densities of four ionic liquids: 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide ([E(3)Mim][Nf(2)]), n-propyl-n-methylpyrrolidinium bis(fluorosulfonyl)imide ([PMpyr][Nf(2)]), 1-butyl-l-methylpyrrolidinium ...
Structural, spectroscopic and computational study of 5-(substituted phenylazo)-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridones
(Wiley, Hoboken, 2018)
Ten 5-(substituted phenylazo)-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridones were studied (five new compounds) to provide insight into the electronic effects of diverse substituents located at different positions in their ...
Efficient multistep arsenate removal onto magnetite modified fly ash
(Academic Press Ltd- Elsevier Science Ltd, London, 2018)
The modification of the fly ash (FA) by magnetite (M) was performed to obtain FAM adsorbent with improved adsorption efficiency for arsenate removal from water. The novel low cost adsorbents are characterized by liquid ...
Amendment Type and Dose Effects onto Coexisting Copper, Lead, and Nickel Ions Distribution in Soil
(Springer International Publishing Ag, Cham, 2018)
The use of soil additives for toxic metals chemical stabilization aims to decrease in situ the pollutants' mobility and availability. In this study, the effectiveness of rinsed red mud (RBRM) and annealed animal bones ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
