Analyzing Heavy Metals in Boxboard Inks: Techniques and Findings

This study focuses on the detection of heavy metals in boxboard inks, supervised by Dr. Kenneth Overway. Key methods include sample collection, acid digestion, filtration, and analysis with an Atomic Absorption Spectrometer (AAS). The results showed no lead or chromium present in the samples, reinforcing the safety of these inks. The study also provided valuable hands-on experience in acid digestion, calibration curve setup, and using the AAS for precise measurements.
