Portable energy dispersive X-ray fluorescence (EDXRF) accurately quantified multiple metals in water. This method enabled rapid analysis of 14 membranes within a 4-hour field study.
Area of Science:
- Environmental Science
- Analytical Chemistry
- Material Science
Background:
- Accurate quantification of metals in water is crucial for environmental monitoring and public health.
- Traditional methods for metal analysis can be time-consuming and require laboratory settings.
- Portable analytical systems offer potential for rapid, on-site environmental assessments.
Purpose of the Study:
- To evaluate the efficacy of a portable energy dispersive X-ray fluorescence (EDXRF) system for quantifying metals in water.
- To determine the range of metal concentrations measurable with the EDXRF system.
- To assess the feasibility of using EDXRF for rapid, field-based membrane analysis.
Main Methods:
- Utilized a portable energy dispersive X-ray fluorescence (EDXRF) system for metal analysis.
- Prepared and measured water samples using the EDXRF system.
- Analyzed 14 membranes within a 4-hour field work period.
Main Results:
- Successfully identified and quantified several metals in water, including Ca, Ti, Mn, Fe, Ni, Cu, Zn, and Pb.
- Achieved quantification ranges in mg L(-1) for the specified metals (e.g., Fe: 1.66-0.035, Pb: 1.01-0.85).
- Demonstrated the ability to process, measure, and analyze 14 membranes in just 4 hours.
Conclusions:
- The portable EDXRF system is effective for the on-site quantification of metals in water.
- The EDXRF method allows for rapid analysis, significantly reducing the time required for environmental sample assessment.
- This technology facilitates efficient field-based monitoring and analysis of water quality through membrane analysis.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
