Chapter 18, Problem 84IE

Interpretation Introduction

Interpretation:

Whether measuring the absorbance of a water sample at $\text{280 nm}$ a good way to detect concentrations of the impurity above $\text{50 ppb}$ threshold is to be stated.

Concept introduction: The beer’s law describes the relationship between concentration of the sample, absorbance, path length and molar extinction coefficient.

To determine: Whether measuring the absorbance of a water sample at $\text{280 nm}$ a good way to detect concentrations of the impurity above $\text{50 ppb}$ threshold.
