This standard describes a method for the determination of iodine content in soil and water system sediments using ammonia closed dissolving and Inductance Coupled Plasma Mass spectrometry. The applicable detection range is 0.23 μg/g to 100 μg/g with a detection limit of 0.07 μg/g. Iodine is extracted by dilute ammonia water heating and determined using Inductance Coupled Inductively Coupled Plasma Mass Spectrometer (ICP-MS) for qualitative analysis with the isotope of iodine. The standard refers to the relevant mass spectrometry analysis specifications and analysis laboratory water specifications to ensure the accuracy and Reliability of the determination results.
