Removal of lead (II) and nickel (II) ions from aqueous solution using activated carbon prepared from rapeseed oil cake by Na2CO3 activation
Uçar, Suat; Erdem, Murat; Tay, Turgay; Karagöz, Selhan (Springer, 2015)In this study, rapeseed oil cake as a precursor was used to prepare activated carbons by chemical activation with sodium carbonate (Na2CO3) at 600 and 800 A degrees C. The activated carbon with the highest surface area of ... -
Removal of Lead (II) Ions from Aqueous Solutions onto Activated Carbon Derived from Waste Biomass
Erdem, Murat; Uçar, Suat; Karagöz, Selhan; Tay, Turgay (Hindawi Publishing Corporation, 2013)The removal of lead (II) ions from aqueous solutions was carried out using an activated carbon prepared from a waste biomass. The effects of various parameters such as pH, contact time, initial concentration of lead (II) ... -
Removal of Orange II from Aqueous Solutions Using N-Vinyl Imidazole-based Hydrogels as Adsorbents
Erdem, Murat; Dikisler, Özlem; Erdem, Bilge (Taylor & Francis Inc, 2016)Poly(N-vinyl imidazole) hydrogel (p-VIm) and its partially quaternized analogue (p-VIm-Ar) were prepared and used for the removal of Orange II (OII). A fourier transform infrared spectrophotometer, scanning electron ... -
Structural stabilities of N-permethylated tetracations of meso-tetrakis(4-pyridyl)porphyrin, meso-tetrakis[4-(dimethylamino)phenyl]porphyrin, and their manganese(III) complexes toward hydrogen peroxide, tert-butylhydroperoxide, and sodium hypochlorite
