In this study, activated carbon was obtained from sugar beet pulp by applying low-temperature carbonization at 350 °C. Removal of phenol aqueous solutions investigated chemical activation process to with HCl and NaOH. For adsorption removal solutions; effects pH, adsorbent dosage, concentration, temperature contact times were investigated. The highest efficiency achieved as 63 % pH 7 for NaOH-treated 0.1 g 100 mg/L 1 hour time, room temperature. Results the experiments showed that kinetics...

Perovskite type oxides which have the general formula as ABO 3 including both rare earth elements and 3d transition metals is gaining interest according to be utilized such strategic materials because of their excellent catalytic, magnetic, electrical optical properties. Along with perovskitic materials, lanthanum nickel oxide (LaNiO -LNO) shows potential a consequence its electronic catalytic properties in not only reactions like reforming, redox but also storage conversion energy or...

Lanthanum strontium aluminum ferrite (La0.8Sr0.2Al0.2Fe0.8O3±δ-LSAF) perovskites are drawing attention as cathodes in solid oxide fuel cells (SOFCs). The structural properties of these materials mostly counting on the methods preparation. In this study, two different preparation namely hydrothermal and sol-gel were applied to prepare LSAF perovskite. characterization results including scanning electron microscopy (SEM), N2 adsorption-desorption, Fourier transform infrared spectroscopy...
