Synthesis of 2-hydroxy-5-nonylbenzophenone (E)-oxime (HNBPO), a reagent especially used for extraction of nonferrous metals from aqueous solutions comprises a two-step sequence using 4-nonylphenol and benzotrichloride as ...

In the case of submerged multijets impinging on to a flat surface, the limiting current densities were measured at microelectrodes, fixed flush with the target surface using diffusion controlled electrode reactions (i.e. ...

Rheological measurements of high and low viscous sodium carboxymethylcellulose solutions in aqueous medium have been made. The concentrations of these solutions are varied from 0.005 to 0.030 g/mL with a view to study the ...

The atomic absorption spectrophotometric (AAS) determination of Fe, Ca, and Mg in the widely used fluoboric-boric acid matrix (HBF4-H3BO3) is seriously interfered with by Si and Al. These interferences can be overcome by ...
