reports two preparation methods of Ni-Al2O3 composite to be used as a hydrogen separation membrane. The first method was powder impregnation while the second method was soaking-drying-firing or bulk... atmosphere. The effect of the preparation method on properties of membranes in terms of density, porosity, phase and microstructure are discussed.关键词:......

April 2018 Abstract: The removal of iron from an Indian diaspore sample was studied using magnetic separation and leaching techniques aided by an in-depth mineralogical characterization study... of physical separation processes to remove the iron. Wet high intensity magnetic separation (WHIMS) studies reveal that only 49% of iron can be removed. Further, leaching studies using oxalic acid suggest......

taken for analysis after phase separation. The total concentrations of zirconium and hafnium in water phase were titrated by EDTA using xylenol orange as indicator. The acidity of filter liquor... for their possible polymerization is difficult to extract into organic phase. So, the increased acidity of water phase is beneficial for extraction. Therefore, acidity has great influence on the separation between......
