Abstract

This research studied the effect of concentration electrolyte (its volume and concentration) and PH on analytical conditions (concentration; slope Nernsty ) and technical conditions were ( time stability ; time response ; speed response) on used fluoride selective Electrode all mesurements measured at degree lab temperature(25C^O). using for this aim five salt as electrolyte : KI ; KCl ; (NH₄)₂SO₄ ; NaCl ; NH₄Cl . for choose best conditions analytical and technical conditions. KCl salt found with concentration 2.5 M and its volume 1.25 ml . time stability 1 min ; time response 7.33 sec; speed response 1 sec and R²=0.9989 then studied PH effect on electrode work using HCl and independently CH₃COOH found in best range PH (5.0 – 6.0) using CH₃COOH and its salt (CH₃COONa) and buffer concentration CH₃COOH = 0.244 ; CH₃COONa= 0.756 M. Best volume from buffer 1.5ml and the work range of buffer PH (3.25 – 8.0( for concentration^5-10×23.1 M and characterized accuracy and was rang Standard Deviation SD= (0.925-0.280) and rang Relative Standard Deviation RSD%=(1.19 – 4.18) and ran Retrospective % 103.0-% 95.6.
