The Control Mode of Extraction Temperature for Water-soluble Fluorine in Soils Measurement by Selective Electrode Method
BACKGROUND The water-soluble fluoride in soil was pretreated by ultrasonic extraction and determined by ion selective electrode. The thermal effect of ultrasonic cavitation can cause the temperature of the extract to rise, and the test result may be unstable, and it cannot truthfully reflect the wat...
