Study on Determination of Fluorine Content in Biodegradable Tape by Calorimetric Bomb-Potentiometric Titration Method
In this study,a method based on calorimetry bomb-potentiometric titration was established to detect fluorine in biodegradable tape.Through a series of experimental designs,a standard curve was established,and the detection and quantification limits,precision,and accuracy of the method were determined.The recovery rate was also evaluated.Finally,the testing method,sample pre-treatment method,and instrument analysis conditions were confirmed,and actual sample testing was conducted.The experimental results comply with the requirements of GB/T 27417-2017"Guidelines for Confirmation and Validation of Chemical Analysis Methods for Conformity Assessment"This method is simple to operate,highly reliable,and can fill the gap in current standard detection methods.
