GB/T 16030-1995 stipulates the determination of hydrogen fluoride and fluoride content in the air of the workshop by Ion selective electrode method. The standard details the required instruments, such as Ion selective electrode and supporting measurement device. Introduces the collection process of air samples, and the collected Sample Handling is turned into a test solution. Using the selective response of the electrode to fluoride ions, the content of hydrogen fluoride and fluoride in the air is accurately calculated by measuring the potential value and combining the standard Linear dispersion. The standard provides a reliable method for monitoring the air environment of the workshop and assessing the fluoride pollution status. It is of great significance to protect the occupational health of workers and prevent fluorosis.
