Scope
This document specifies the determination of iodides in drinking water and source water using the arsenic-cerium catalytic spectrophotometry method. The minimum detectable concentration of iodides in this document is 0.2 μg/L (I-), and the determination range includes low-concentration iodides [0 μg/L (I-) to 10 μg/L (I-)] , medium-concentration iodides [10 μg/L (I-) to 100 μg/L (I-)] , and high-concentration iodides [100 μg/L (I-) to 600 μg/L (I-)] .
