A new solid phase extraction method accurately speciates chromium(III) and chromium(VI) in environmental samples. This technique offers a reliable way to analyze chromium levels in water, soil, and food products.

Area of Science:

  • Analytical Chemistry
  • Environmental Science
  • Materials Science

Background:

  • Chromium speciation is crucial for environmental and health risk assessment.
  • Existing methods for chromium speciation can be complex and time-consuming.
  • Accurate determination of Cr(III) and Cr(VI) in diverse matrices is challenging.

Purpose of the Study:

  • To develop and validate a solid phase extraction (SPE) method for chromium speciation.
  • To determine Cr(III) and Cr(VI) concentrations in real environmental samples.
  • To establish a reliable and sensitive analytical procedure for chromium analysis.

Main Methods:

  • Solid phase extraction using Chromosorb 108 resin for Cr(III) adsorption as a dithizonate chelate.
  • Reduction of Cr(VI) to Cr(III) for total chromium determination.

Related Experiment Videos

  • Calculation of Cr(VI) by difference: Total Cr - Cr(III).
  • Optimization of parameters: pH, dithizone amount, eluent, sample volume, and flow rates.

    • Main Results:

    • The method demonstrated high selectivity with no significant interferences from other ions.
    • Adsorption capacity of the sorbent was 4.50 mg/g for Cr(III).
    • The detection limit for Cr(III) was as low as 0.75 µg/L.
    • Accurate speciation was achieved in natural waters, tobacco, coffee, and soil samples.
    • Analysis of certified reference materials yielded results with relative errors and standard deviations below 5% and 9%, respectively.

    Conclusions:

    • The proposed SPE method is effective and accurate for chromium speciation in various environmental samples.
    • The method provides a sensitive and reliable approach for analyzing Cr(III) and Cr(VI).
    • This technique is suitable for preconcentration and speciation of chromium in complex matrices.
