3.3 Atomic Emission Spectroscopy (AES) Results for Sodium (Na), Calcium (Ca),
and Magnesium (Mg) in Organic and Non-Organic Banana Samples:
3.3.1 Sodium (Na)
Atomic Emission Spectroscopy (AES) was used to measure the sodium content in banana
samples that were both organic and non-organic. Four sodium standards with concentrations
ranging from 78.13 ppb to 1250 ppb were used for calibration. By using the standards' intensity
values to create a calibration curve, it was possible to determine the samples' sodium
concentrations using the intensities that were measured. Table 3.3.1 displays the standards
and their related intensity values, and Graph 3.3.2 displays the calibration curve that results
from given values.
