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

Dr. Ahmed Fadhil Khudhair | Shaymaa Ibrahim Saeed

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) g. mL-1, with correlation coefficient r =0.9973 and limit of detection (0.047 g. 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.
