TE”lTIE USE of dextrall sulfate has beell employed for the precipitation of serum $ iipoproteins (1). 1)allgerfield and Faulkner used dextran sulfate ill tile presence of calcium iOhlS to l)recipitate tue low-density lipoproteills (2). While investigating the precipitation properties of a large molecular weight dextran sulfate in the presence of calcium chloride, we obtained a precipitate from ...

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 ...

Backgrounds & objectives: Contamination of the environment by heavy metals, pollute water and agricultural products. The aggregation of these metals will cause various diseases for human. Therefore, it is important to study how to make them safe. The purpose of this study is to evaluate the efficiency of starch-iron oxide nanocomposite in removing two heavy metals, nickel and cadmium, from wast...
