Determinación de boro en agua por método fluorimétrico

INTRODUCCIÓN

The method is designed to measure mass concentration of boron in samples of natural, drinking, and waste water by fluorimetric method using the FLUORAT®-02 analyzer.

MÉTODO DE MEDICIÓN

Fluorimetric method for the determination of boron is based on the complex formation of borate ions with chromotropic acid in the presence of N,N,N’,N’-ethylenediaminetetraacetic acid, disodium salt (EDTA disodium salt) as a masking agent for heavy metal ions. The intensity of fluorescence of formed complex is measured by FLUORAT®-02 analyzer and displayed as boron concentration in mg/l. The result appears on PC-operated software FLUORATE.
