| Abstract | ||
| In this research the drug nicotinamied (NA) is determined with new method using spectrophotometer by forming ion-pair with [BiI4]-1 complex after extraction with 1,2-dichloro ethane spectrum at 290 and 382 nm wave length. Was the quick reaction and pH=2, 4/3.7ml aqua phase / organic phase ratio, at temperature 25 °C with 3 minute mixing time and at 98.85, 98.88 percent extraction ratio in one at the 290, 382 nm respectively. The statistical and analytical rustle for formed ion-pair complex for concentration rang between 1.63X10-6-3.24X10-5M are as follow: D.L=1.94X10-9, 1.66X10-9 M, r = 0.9960, 0.9961, molar absorption coefficient 63435, 35496 Sandl's sensitivity=0.0019 ,0.0034µg/cm2 at 290 and 382 nm respectively, it was found that the complex stable for 72 hour at least with Rec 95.74 ,97.17% at the wave length of determination .Using P-BLEX syrp as practical application it was found that Rec 102.84, 101.69and Eerl%2.84 , 1.691 at the both length 290,382 nm respectively. | ||
