The method consists on solid dilution with MgSO4 as sample preparation method. Reagents concentration and ratio were optimized to analyze complex substrates (from 5 to 2,500 g COD Kg-1 TS). Comparison with the standard titrimetric method demonstrated much better precision and accuracy, allowing a significant decrease on chemicals consumption and toxic waste generation.
