A new direct method accurately measures acid-volatile sulfide (AVS) in sediments quickly and efficiently. This technique offers a faster alternative for sediment quality assessment and metal contamination evaluation.

Area of Science:

  • Environmental Chemistry
  • Analytical Chemistry
  • Geochemistry

Background:

  • Acid-volatile sulfide (AVS) is a crucial parameter for assessing sediment toxicity and metal bioavailability.
  • Traditional methods for AVS determination are often time-consuming and require specialized equipment.

Purpose of the Study:

  • To introduce a novel, direct method for quantifying acid-volatile sulfide (AVS) in sediments.
  • To evaluate the method's speed, efficiency, and applicability in sediment quality assessment.

Main Methods:

  • Direct reaction of sediment with Cline's reagent.
  • Colorimetric determination of AVS.
  • Comparison with established purge-and-trap AVS methods.

Main Results:

  • The direct method provides fast analysis times without specialized equipment.
  • A strong linear relationship (r = 0.986, p < 0.001) was observed between the direct and purge-and-trap methods.
  • Sample throughput is over 10 times higher than traditional methods, despite a slight underestimation of AVS concentration.

Conclusions:

  • The direct AVS method is a rapid and efficient technique for sediment analysis.
  • This method is suitable for rapid screening of AVS concentrations and evaluating sediment quality related to metal contamination.
