Effect of incorporating graphene oxide and surface imprinting on polysulfone membranes on flux, hydrophilicity and rejection of salt and polycyclic aromatic hydrocarbons from water

Autor: Titus A.M. Msagati, Rose Waithiegeni Kibechu, Srinivasan Sampath, Derek Tantoh Ndinteh, Bhekie Briliance Mamba

Publikováno v: Physics and Chemistry of the Earth, Parts A/B/C. 100:126-134

We report a significant enhancement of hydrophillity of polysulfone (Psf) membranes after modification with graphene oxide (GO) as a filler followed by surface imprinting on the surface of GO/Psf composite imprinted membranes (CIMs). The surface impr

Pre-Electrospray Ionisation Manifold Methylation and Post-Electrospray Ionisation Manifold Cleavage/Ion Cluster Formation Observed during Electrospray Ionisation of Chloramphenicol in Solutions of Methanol and Acetonitrile for Liquid Chromatography-Mass Spectrometry Employing a Commercial Quadrupole Ion Trap Mass Analyser

Autor: Rose Waithiegeni Kibechu, Kwenga Sichilongo, Samson O. Famuyiwa

Publikováno v: European Journal of Mass Spectrometry. 17:255-264

We have observed unusual mass spectra of chloramphenicol (CAP) in solutions of methanol or acetonitrile showing intense ions at m/z 297, m/z 311, m/z 325 and m/z 339. The ions observed were different from those which are traditionally observed in the

Graphene-based molecularly imprinted polymer for separation and pre-concentration of trace polycyclic aromatic hydrocarbons in environmental water samples

Autor: Titus A.M. Msagati, Srinivasan Sampath, Rose Waithiegeni Kibechu, Bhekie B. Mamba

Publikováno v: Journal of Applied Polymer Science. 134:45300

A composite of reduced graphene oxide and pyrene-imprinted polymer was synthesized and employed as a solid phase for extraction of five selected polycyclic aromatic hydrocarbons (PAHs) from water samples. Gas chromatography-time of flight/mass spectr
