solutions of Pbt and AAS analysis. The calibration curve for the analysis is shown below. Considering the Pb* unknown sample gave an intensity of 16.5, what is the concentration in the unknown sample (1 Mark) >> 20 15 Emission Intensity 10 y = 2.0714x + 0.4762 R?=0.9969 10 25 Pb Concentration, mg/L a. 34.65 mg/L O b. 77.4 mg/L OC. 7.74 mg/L O d. 7.74 M PREVIOUS PAGE NEXT PAGE
In a similar experiment you did for Atomic Absorption Spectroscopy (AAS), AAS was used to analyse Pbt in river water sample and therefore a calibration curve of Pbt was made by using diluted standard
