| Abstract | ||
| This Study includes the determination of (TFPH) drug via the formation of ion associationpair with lpdl.{]-2 and with IBi14]'' in aqueous phase . The analytical results obtained are as follow: theoptimum pH is 5 and 4, reaction time is immediate and 5 minutes, mixing time 3 and 4 minutes for thetrvo ion pair respectively. The statistical and other analytical results for the first ion pair in theconcentration range (6-40ppm) were as follow: the detection limit is 0.228 ppm, molar absorptioncoefficient is 2.3635x100 liter mole-r crn-r at 297nn'r. For Bil.r -TFPIj ion pair at292 nnr, the r.ruit, inthe concentration range (0.2-l8ppm) were as follorv: detection limit is 0.0030 ppm, and molarabsorption coefflcient is 3.747 x 104 liter mole'' cm'r This method *at uipti.d to Salabidpharmaceutical preparation rvith percentage recovery of not less than 985%. | ||
