Calcium oxide nanoparticles was prepared by coprecipitation method using calcium acetate as precursor and calcined at 800 °C for 6 hours. This work studied the effect of different concentrations on size obtained its applicated palm oil transesterification catalysis. Characteristics samples were measured XRD SEM et al techniques. The results showed that diffraction pattern CaO has same standard ...

This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosfate. The analytical parameters that influenced the quantitave coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. The % recoveries of the analyte io...

The present study examined the effect of three methods of preparation on the properties and catalytic performance of Cu-Mn/SiO2 catalysts for the water gas shift reaction (WGSR). Impregnation and coprecipitation and the new approach of thermal decomposition of [Cu(H2O)6][Mn(dipic)2].2H2O/SiO2 inorganic precursor complex were used for the synthesis of the silica-supported copper-manganese mixed ...
