A mixture of manganese dioxide-lithium sulphate-sulphuric acid has been used for accurate and precise estimation of chromium in various chromite matrices. Inter-method comparison studies show that the proposed procedure ...
From the resin of Shorea robusta, in addition to three known triterpenoids, a new nor-triterpene 3beta-acetoxy-28-nor-urs-12-ene has been isolated. The structure of the new triterpene was established by photochemical ...
This investigation has been aimed at developing a method for characterizing and predicting the performance of collectors based on pressure-area isotherms. This procedure can be used both to choose the proper collector and ...
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 ...
