| Abstract: | A rapid and simple method for the test of trace F in hydrochloric acid using F~--ISE, removing CL~- by AgNO_3 was presented.The slope of the electrode was 58.0mV.The suitable pH value was 5, and the Nernst Linear range was 0.5～5×10~(-5)M.The standard deviation was 5×10~(-5)%, the CV<6%, and the recovery was 91.8%～104.0%. |
