GB/T 42333-2023
Introduction
GB/T 42333-2023 Determination of iodine content in soil and water sediment by ammonium water sealed dissolution-inductively coupled plasma mass spectrometry (ICP-MS) is a national standard of China. This standard specifies the method for determining the total content of iodine in soil and water sediment using ammonium water sealed dissolution-inductively coupled plasma mass spectrometry.
The method involves the use of ammonium water to dissolve the sample, followed by analysis using inductively coupled plasma mass spectrometry. This technique allows for accurate and reliable measurement of iodine content in soil and water sediment samples.
The standard provides detailed procedures for sample preparation, including the selection and collection of samples, as well as guidance on the calibration of instruments and quality control measures. It also outlines the calculation method for determining the iodine content in the samples.
This standard is applicable to the determination of iodine content in various types of soil and water sediment samples, and can be used for environmental monitoring, agricultural research, and other related fields.
In conclusion, GB/T 42333-2023 provides a standardized and reliable method for the determination of iodine content in soil and water sediment samples using ammonium water sealed dissolution-inductively coupled plasma mass spectrometry. By following the procedures outlined in this standard, accurate and reproducible results can be obtained for various applications.
