INTRODUCTION

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.

METHOD

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.
