Interpretation Introduction

(a)

Interpretation:

The reason for decrease in atomic absorption signal for iron in presence of large concentration of sulphate ion in hydrogen-oxygen flame needs to be explained.

Concept introduction:

In a defined space, the amount of a substance gives its concentration. A substance’s capacity to absorb specific wavelength light gives its absorbance.

Interpretation Introduction

(b)

Interpretation:

The ways of overcoming interference of sulphate in iron determination needs to be explained.

Concept introduction:

In a defined space, the amount of a substance gives its concentration. A substance’s capacity to absorb specific wavelength light gives its absorbance.

In a hydrogen-oxygen flame, the atomic absorption signal for iron was found to decrease in the presence of high concentrations of sulfate. Suggest an explanation for this observation and propose one possible method for overcoming the potential interference of sulfate in the quantitative determination of iron.

Describe the steps of the process in the correct sequence.           (c) State TWO interferences that are encountered in atomic absorption spectrometer. Suggest ONE solution to overcome the problem.             (d.) What is the main difference, in terms of instrumentation, between atomic absorption spectrometer and atomic emission spectroscopy?
Alexa Fluor 568 is a fluorescent dye that in aqueous solution displays a maximum absorbance at 576 nm, a quantum yield of 0.69, a lifetime of 3.60 ns and a Stokes shift of 24 nm. (i) Show a schematic of a typical fluorimeter and its main components. Briefly explain the role of each component. (ii) Explain what is the "Stokes shift" and what physical processes underpin the observation of such shifts; use diagrams and/or equations as appropriate in your explanation. (iii) Calculate the radiative decay constant of Alexa Fluor 568.
