Judul : DEVELOPMENT OF COD (CHEMICAL OXYGEN DEMAND) ANALYSIS METHOD IN WASTE WATER USING UV-VIS SPECTROPHOTOMETER
Abstrak :

Abstract.  The COD (Chemical Oxygen Demand) analysis method based on the Indonesian National Standard (SNI) is a
revision of SNI 06-6989.2-2004, Water and wastewater - Part 2: Method of testing for chemical oxygen demand (COD)
with closed reflux spectrophotometrically. This SNI uses references from international standard methods, namely
Standard Methods for the Examination of Water and Wastewater, 21st Edition, editor of LS Clesceri, AE Greenberg, AD
Eaton, APHA, AWWA and WEF, Washington DC, 2005, Methods 5220 D (Closed Reflux, Colorimetric Methods). The
purpose of this study was to validate the total method for testing chemical oxygen demand (COD) in water and
wastewater with the reduction of Cr2O72- spectrophotometrically in the range of COD values of 100 mg / L to 900 mg /
L measurements were made at a wavelength of 600 nm. and COD values less than or equal to 90 mg / L measurements
were made at a wavelength of 420 nm. The results showed that the method SNI 06-6898.2- 2009  has good validation
results including the r results obtained from the calibration curve equation of 0.998, a precision of 1.82%, an accuracy of
98.25% and LOD and LOQ of 12.27 mg / L and 25, 61 mg / L. 

Keywords: wastewater; COD analysis; UV-VIS spectometry; validation, LOD
