In order to determinate fluorine in compound fertilizer effectively,four extraction methods including HCl leaching extraction overnight,ultrasonic solvent extraction,alkaline fusion digestion,pure water boiling digestion were studied.It can be included that similar results can be achieved through both ultrasonic solvent extractionby HCl and alkali fusion digestion method.The recovery is 98.4%~104.2%with 1.9% RSD.Therefore,ultrasonic solvent extraction method is reliable,convenient and fast,and… CONTINUE READING
