Method Abstract #1

Scope and Application

This method conforms to MOECC Method E3515 and ASTM D8084-17. Sample types include drinking water, wastewater, source and natural water, and industry specific water streams

Method Summary

The PeCOD® is a unique nanotechnology based photo-electrochemical technique to determine soluble chemical oxygen demand (COD) in natural and wastewater samples in a simple, rapid, direct and absolute fashion. The PeCOD® approach utilizes photocurrent/charge originating from oxidizing organic species contained in the sample to quantify COD.

Quality Control
