Total mercury determination in water by CVAAS

Mercury determination in surface, drinking and waste waters by Cold Vapor-Atomic Absorption Spectrophotometry (CVAAS) Lumex Instruments 833

INTRODUCTION

Mercury determination in surface, drinking and waste waters is one of the most popular analyses used for environment pollution and sanitary control.

MEASURING METHOD

The method is based on the cold-vapor technique (CVAAS). Samples of natural and waste water must be pre-treated using the appropriate standard digestion procedures. Detection limit (DL) is 0.00005 ng of Hg which corresponds to 0.0001 μg/L (0.1 ng/L) for sample volume 5 mL. The working range of the method is determined by the measured mercury concentration in the blank sample and starts from 50 % of Сblank value.
