Surface area of antimony oxide by isotope exchange and other methods

Autor: B. V. Acharya, B. Rangamannar, Y. K. Rao

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Letters. 94:363-372

Specific surface area of antimony oxide samples, one commercial and the other prepared from antimony trichloride have been measured by heterogeneous isotope exchange, gas adsorption, airpermeability and microscopic methods. Specific surface areas obt

Determination of mercury by radiochemical displacement

Autor: B. Rangamannar, B. V. Acharya

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Letters. 95:127-130

2–15 μg of mercury has been determined by exchange with zinc in65Zn labelled zinc sulphide. The influence of various ions which are likely to interfere in the determination of mercury has also been studied.

Determination of manganese by radiochemical displacement

Autor: K. V. Varma, B. Rangamannar, B. V. Acharya, J. Sankaraiah

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Letters. 96:27-30

The possibility of determination of 10–80 μg of manganese by radiochemical displacement of zinc from a labelled zinc-PAN complex has been demonstrated. pH 6 borate buffer was suitable for quantitative displacement. The effect of diverse ions on th
