Abstract
Currently, dissolved oxygen (DO) contents have been analyzed in the laboratory. The results were not satisfactory due to the instability of the dissolved oxygen in the water samples. The problem could be solved by analyzing samples immediatly at the sampling site.
The conventional Azide method could be developed to analyze at the sampling site and called "the modified method" the correlation between the Azide and the modified method was 1. DO analyzed by the modified method must be lower than the Azide method 7.34 and 10.51 ppm respectively. The conversion factor of the modified to the Azide method was 1.431. DO calculation in ppm of modified method must there fore be: ml. of titrant x 14.31
