Simple and Quick Analysis for Mercury in Environmental Water using Alkaline Reduction Method along with Enclosed Quartz Cell-Cold Vapor Atomic Absorption Spectrometry

Abstract

A simple and quick analytical method for mercury in environmental water was developed by combining the enclosed quartz cell cold vapor atomic absorption spectrometry (EQC-CV-AAS) and alkaline reduction pretreatment. The advantages of this method include reduction in the mercury measurement time from 3 h to 5 min and possibility of the on-site mercury monitoring for environmental water matrix such as river and sea water. A quick analytical method for mercury was developed by combining the enclosed quartz cell cold vapor atomic absorption spectrometry and alkaline reduction pretreatment. The advantages of this method reduction in the measurement time from 3 h to 5 min and lower LOQ value than that proposed by the Water Pollution Prevention Act by the Ministry of the Environment, Japan.
