Simple bead injection-flow injection system for the determination of copper

Area of Science:

• Analytical Chemistry
• Environmental Chemistry

Background:

• Accurate determination of trace metal ions like copper (Cu2+) is crucial for environmental monitoring and quality control.
• Existing methods for Cu2+ determination can be complex, time-consuming, and require extensive sample pretreatment.

Purpose of the Study:

• To develop and validate an extended application of a simple bead injection-flow injection system for the sensitive determination of Cu2+.
• To assess the method's applicability to diverse sample matrices, including water and supplement tablets.
• To minimize sample pretreatment requirements for a more efficient analytical process.

Main Methods:

• Utilized a bead injection-flow injection analysis (BIA-FIA) system.
• Employed a modified colorimetric detection unit for Cu2+ quantification.
• Used ammonium pyrrolidinedithiocarbamate (APDC) as the chelating reagent for copper complex formation.
• Analyzed water samples and supplement tablet digests.

Main Results:

• Successfully determined low concentrations of Cu2+ in different matrices.
• Demonstrated minimal sample pretreatment, simplifying the analytical workflow.
• The BIA-FIA system with APDC reagent showed effective application for trace copper analysis.

Conclusions:

• The bead injection-flow injection system offers a simple, efficient, and adaptable method for Cu2+ determination.
• This approach is suitable for analyzing various real-world samples with reduced sample preparation.
• The method provides a valuable tool for routine monitoring of copper levels.
