GB/T 15434-1995 《Ambient air--Determination of the mass concentration of fluoride--Method by filter sampling andfluorine ion-selective electrode analysis》 Related products
This standard specifies percolated membrane collection and fluorine Ion selective electrode method for the determination of fluoride concentration in ambient air. This method is capable of detecting fluoride with a minimum concentration of 0.5 μg/m ³ and is suitable for environment air monitoring. Fluoride is fixed when a known volume of air passes through a filter membrane impregnated with dipotassium hydrogen phosphoric acid, and then is determined by fluorine Ion selective electrode method after being impregnated in muriatic acid solution. This standard specifies in detail the reagents, instrumentation and procedures to ensure the accuracy and Reliability of test results.
