Interfacial Adsorption of 5-Octyloxymethyl-8-quinolinol over a Range of pH
A high speed stirring method was used to measure the adsorption behavior of 5-octyloxymethyl-8-quinolinol (Hocqn) at the chloroform= water interface over a range of pH 1 13. Results showed the increase in adsorptivity of Hocqn at both low and high pH conditions and indicated that the protonated form (H2ocqn 2þ) was more adsorbable at the interface than the deprotonated form (ocqn ) of this mole...
متن کاملAngle-controlled arrangement of single-walled carbon nanotubes solubilised by 8-quinolinol metal chelate derivatives on mica.
We solubilised SWNTs of short length using a mechanochemical high-speed vibration milling (HSVM) through formation of complexes between the SWNTs and chelate complexes; the mixture formed a network structure on mica.
متن کاملSynergistic effect of 3,5-dichlorophenol and trioctylphosphine oxide on the extraction of vanadium(V) with 2-methyl-8-quinolinol derivatives.
The extraction of vanadium(V) with 2-methyl-8-quinolinol derivatives (HA), such as 2-methyl-8-quinolinol (HMQ), 2-methyl-5-butyloxymethyl-8-quinolinol (HMO4Q), and 2-methyl-5-hexyloxymethyl-8-quinolinol (HMO6Q), from a weakly acidic solution into chloroform was studied in both the absence and presence of 3,5-dichlorophenol (Hdcp) and trioctylphosphine oxide (TOPO) as the synergists. Vanadium(V)...
متن کاملSolid-phase extraction of gallium(III) with hydrophobic 8-quinolinol derivatives-impregnated resin from aqueous acidic and alkaline solutions.
Solid-phase extraction (SPE) of gallium(III) with hydrophobic 8-quinolinol derivatives (HQs)-impregnated resin from aqueous acidic and alkaline solutions has been investigated. The HQs used were 7-(4-ethyl-1-methyloctyl)-8-quinolinol (HEMOQ), 5-octyloxymethyl-8-quinolinol (HO(8)Q), 2-methyl-5-octyloxymethyl-8-quinolinol (HMO(8)Q), 5-dioctylaminomethyl-8-quinolinol (HN(8)Q), 7-bromo-5-octyloxyme...
متن کاملCrystalline Acetyl Derivatives of Pepsin
Crystalline pepsin has been acetylated by the action of ketene in aqueous solution at pH 4.07-5.5. As acetylation proceeds the activity decreases, the decrease being more rapid at pH 5.0-5.5 than at 4.0-4.5. Three acetyl derivatives have been isolated from the reaction mixture and obtained in crystalline form. The crystal form of these derivatives is similar to that of pepsin. Fractionation and...
