Removal of Pb(II) from Aqueous Solutions by Zeolites, Porcelanite and Sands: Correlation of Morphology and Chemical Composition to Batch Removal Efficiency
Jumean, Fawwaz; Pappalardo, Lucia; Khoury, Hani (Scientific Research Publishing, 2015-03)Chemical compositions of natural zeolites, porcelanite (opal-CT) and local sands were determined by X-ray fluorescence (XRF) and correlated with their Pb(II) removal efficiencies. Zeolites and porcelanite were from the ... -
Utilizing active learning strategies to enhance learning in first year university chemistry courses
Pappalardo, Lucia; Gunn, Cindy (Zayed University Press, 2013)Teaching chemistry to non-science majors can be a challenge in higher education owing to students’ perceptions of the subject’s difficulty, and of its usefulness. In order to address these challenges, the authors applied ...
