Study on the Releasing Characteristics of Slow-release Sodium Fluoride Tablet in Different Conditions

This experiment studied the releasing characteristics of slow--release sodium fluoride tablet in water or buffers withdifferent pHs and under different rotation speeds.The results showed that there was no correlation between the release rate and thePH of releasing medium,and there was correlation between the release rate and the rotation speed.The release model and the data ofthe releasing characteristics were established for quality control.
