Dioxins Analysis in the Environment

U.S. EPA Method 1613B has been one of the primary methods used in the analysis of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in wastewater, soils, sludges, and other matrices. These compounds have more than 200 congeners, and seventeen of them are highly toxic and of interest in trace analysis. Historically, these analyses have been performed using magnetic sector high-resolution GC/MS. In 2021, the U.S. EPA approved an alternate testing protocol (ATP) that accepts GC/TQ as an equivalent technology for the analysis of dioxins in environmental samples.  This work shows the Agilent triple quadrupole GC/MS system can achieve the sensitivity required to meet and exceed guidance for the analysis of PCDD/PCDFs at all concentration levels.

EnviroTech – Transforming Wastewater Treatment with TOC Monitoring

Organic load is one of the most important parameters for discharge control of municipal and industrial wastewater. Permissible limits are guided through regulations and must be monitored accordingly. However, further opportunity to optimize plant performance exists by monitoring organic loading in upstream treatment processes.

The use of on-line controls allows limit values to be adhered to, products to be saved, and plants to be protected against unforeseen events. Total Organic Carbon (TOC) is the most suitable parameter to measure organic load. The use of TOC analysis offers shorter measuring cycles without hazardous waste and is better suited for on-line analysis compared to conventional methods such as COD or BOD.

 

What you’ll learn

  • Differences between TOC, BOD and COD, and why TOC is more suitable for on-line control
  • Differences in TOC technologies
  • How TOC can help optimize your plant
  • Examples and case studies of how TOC can be utilized
