Complexo-potentiometric determination of mercury (II) in chlormerodrin and mercuric chloride labelled with radioactive mercury

Creators

Description

A method is described for determining the amount of mercury (II) in radioactively labelled chlormerodrin and mercuric chloride. By measuring the absolute activity in an ionization chamber, the specific activity is therefore immediately obtained. The determination of Hg (II) is based on a complexometric titration. Because of method characteristics and speed convenience, the end point is observed by means of a pH-meter. A comparison is made with a determination performed by detecting the end point with color-change indicators. The error is estimated, and the results are statistically interpreted. (author)

Abstract (Spanish)

Se describe un metodo para la determinacion del mercurio (II) en clormerodrina y cloruro de mercurio radiomarcados. Habiendose obtenido previamente la actividad del compuesto en la camara de ionizacion, el calculo del valor de la actividad especifica resulta inmediato. La determinacion se basa en una titulacion complejometrica, cuyo punto final se observa con un ''pehachimetro'' debido a las caracteristicas del metodo y a la rapidez que permite en la medicion. Comparativamente se indican los resultados obtenidos en una valoracion cuyo punto final se detecta con una mezcla de indicadores. Se estima el error cometido y se interpretan estadisticamente los resultados. (autor)
