title = "Analytical determination of Chemical Oxygen Demand in samples considered to be difficult to analyse: solid substrates and liquid samples with high suspended solid concentrations",
abstract = "Chemical oxygen demand (COD) is a critical analytical parameter in the field ofwaste and wastewater treatment processes, and more specifically in anaerobicdigestion processes. However, little is known about the COD measurement quality ofanaerobic digestion samples. Taking into account the lack of a general standardmethod and high quality certified reference materials (CRMs), currently thetraceability of the COD determination in such samples is not easy to check.Proficiency testing (PT) is a powerful tool that can be used to test the performancethat the participant{\textquoteright}s laboratories can achieve. Two PTs related with CODdetermination have been organised, and the results reported have been compared;showing the importance of continuous participation in proficiency testing (PT)schemes in order to improve the results obtained.",
