GLRPPR Sector Resource: Treatment of Spent Chemical Oxygen Demand Solutions for Safe Disposal

Title:
Treatment of Spent Chemical Oxygen Demand Solutions for Safe Disposal

Abstract:
The chemical oxidation demand (COD) test is used in numerous laboratories to characterize wastewater and effluent. The goal of this project was to develop an effective and convenient method to treat COD waste for safe disposal. The effectiveness and convenience criteria were a Hg concentration less than 3 micrograms/L and no intermediate steps such as filtration. Precipitation of HgS was the basis of the procedure. Chemical equilibrium modeling and experiments were used to develop the treatment procedure. The modeling was used to design the experiments while the experimental data were used to test the model.
