Quantitative Analysis of Bismuth (III) Ion by Coupling Turbidy Method with Cloud Point Extraction Mode

Abstract

Abstract:A new turbidimetric method is described for the determination of bismuth(III) ion .This method is based reaction between Bi(III) ion with fuchsine reagent and Sodium dodecyl sulfate (SDS) as a surfactant compound in aqueous medium to form red ion-pair complex as turbid phase .The product was determined by using batch turbidimatric method.. All optimization parameters were studied. The calibration graph was linear in the range of (0.05 -25)µg.mL -1 , with correlation coefficient r =0.9973 and limit of detection (0.047 µg.mL -1 ).A comparison was made between the newly developed method analysis with classical method using standards addition method via the use of t-test it was noticed that there was no significant difference between two methods at %95 confidence level.
