Analysis of Bi in Hydrochloric acid by Hydride Generation Method


Bismuth is a brittle metal with a white, silver-pink hue, often with an iridescent oxide tarnish showing many colors from yellow to blue. The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth rate around the outside edges than on the inside edges. The variations in the thickness of the oxide layer that forms on the surface of the crystal cause different wavelengths of light to interfere upon reflection, thus displaying a rainbow of colors.

HFS-4 - Hydride Formation System for Hitachi AAS

Hydrochloric acid containing bismuth at 1 μg/L was analyzed by the hydride generation method. The atomic absorption signal is stable due to the double beam effect of the polarized Zeeman correction and bismuth at 1 μg/L can be analyzed with a good accuracy.
