Quantitative emission spectral analysis of boron contained in a liquid solution, whose concentration ranges between 0.015 and 0.15 per cent., was studied by using a new type liquid electrode. The amount of boron in a solution acidified with hydrochloric acid was determined from the AS of the line pair of B 2497.7 Å/Zn 2502.0 Å using zinc as an internal standard. The analytical accuracy in this procedure was ±4.36 per cent.
The method was applied to the determination of boron in tourmaline and some hot-spring waters of Akin, Miyagi Prefecture.
