GB/T 15433-1995 《Ambient air--Determination of the fluoride--Method by lime-paper sampling and fluorine ion-selective electrode analysis》 Related products
This standard specifies a method for collecting fluoride using lime filter paper and measuring it by fluorine Ion selective electrode method, which is suitable for determining the long-term average concentration of fluoride in the air of the environment. Sampling time is one month, the lower limit of the method is 0.18 μg/dm/day. The standard describes in detail how fluoride in the air reacts and immobilizes with filter paper impregnated with calcium hydroxide, and then determines its content by electrode method, thereby reflecting the level of fluoride pollution in the air.
