Measurement of Cesium in Tap Water and Soil by Atomic Absorption Spectrometry

Introduction

Recently, technologies that can efficiently remove radioactive cesium (chiefly Cs-137) from water and soil have been actively researched. The study and evaluation of these removal technologies can be conducted using Cs-133, an easy-to-handle, stable substance, yet chemically similar to Cs-137. Cesium can be analyzed using atomic absorption spectrometry and ICP emission spectroscopy, which are therefore effective for researching and evaluating the various removal technologies. Here, we introduce examples of analysis of cesium in tap water and soil using the AA-7700 atomic absorption spectrophotometer.
