Oxolane-2,5-dione modified electrospun cellulose nanofibers for heavy metals adsorption

Musyoka, Stephen M.; Ngila, Catherine; Moodley, Brenda; Kindness, Andrew; Petrik, Leslie; Greyling, Corrine (Elsevier, 2011-08-30)

Functionalized cellulose nanofibers have been obtained through electrospinning and modification with oxolane-2,5-dione. The application of the nanofibers for adsorption of cadmium and lead ions from model wastewater samples ...
A solid phase extraction procedure based on electrospun cellulose-g-oxolane-2,5-dione nanofibers for trace determination of Cd, Cu, Fe, Pb and Zn in gasoline samples by ICP-OES

Musyoka, Stephen M.; Nomngongo, Philiswa N.; Ngila, Catherine, J.; Msagati, Titus A.; Moodley, Brenda (Royal Society of Chemistry, 2013)

Cellulose-g-oxolane-2,5-dione nanofibers were prepared as an adsorbent for simultaneous separation and preconcentration of trace amounts of Cd, Cu, Fe, Pb and Zn ions in gasoline samples prior to ICP-OES detection. The ...
Synthesis, Characterization, and Adsorption Kinetic Studies of Ethylenediamine Modified Cellulose for Removal of Cd and Pb

Musyoka, Stephen M.; Ngila, Jane C.; Moodley, Brenda; Petrik, Lesley; Kindness, Andrew (Taylor & Francis, 2011)

Surface functionalization of cellulose using ethylenediamine was performed to improve its binding capacity for Cd and Pb. Adsorption kinetics at pH 6.0 and 25°C revealed the Langmuir model to better describe the binding ...
