Colorimetry as an Alternative Tool for the Determination of Chemical Oxygen Demand in Sugar Mill Waste
Dayao, C.A.S., Mundo, R.H.B., et.al. 1996. Evaluation of the colorimetric method and the dichromate reflux method on the determination of chemical oxygen demand (COD) was conducted on 26 wastewater samples on various sampling points of CADP. T-test showed that the colorimetric method has no significant difference with the reference method. PROCEEDINGS OF THE PHILIPPINE SUGAR TECHNOLOGISTS. August: 278-284.
