Abstract
This study introduced an analytical approach
for directly measuring chromium in baby formula using high-resolution continuum
source electrothermal atomic absorption spectrometry along with solid sample
analysis (AAS). The method for analyzing heavy metals involved Inductively
Coupled Plasma – Optical Emission Spectrometry (ICP-OES), which allows for
quick and precise detection of trace elements. It's also important to note that
many labs are now using inductively coupled plasma–mass spectrometry for even
more sensitive metal analysis. The results from stability tests showed that
using appropriate masking agents improved the reagent's selectivity and reduced
interference from other metal ions such as copper (II) and iron (III).
Therefore, this method is suggested for concentrating and measuring chromium
(VI) at low levels using AAS, and it can also be used for analyzing real-world
samples like industrial waste.
