Abstract: BAYHON, ANALYN DE VEGA, " Development of Dissolved Oxygen Test Kit for Water Analysis Application", an Undergraduate Thesis, Bachelor of Science in Chemistry. October 2001. Cavite State University, Indang, Cavite. Adviser: Mr. Francisco M. Heralde Ill. The study "Development of Dissolved Oxygen Test Kit for Water Analysis Application" was conducted at the Department of Physical Sciences, Cavite State University, Indang, Cavite from January to May 2001. Three methods of dissolved oxygen determination were compared as to availability of materials, ease of assay, cost, and accuracy of results. These methods were the Winkler Method, Indigo Carmine Method and the Manganese Complexation Method. Results of the comparison showed Winkler as the most suitable method based on accuracy and ease of assay although it costs higher than the other two methods. A modified protocol of Winkler method was used to design a DO test kit. For the DO test kit to be portable, the volume of reagents and samples to be used were reduced. Amber bottles with dropper cover were used as containers of reagents and a transparent test bottle was used as a sample container. Syringe was used for titration. Different concentrations of dissolved oxygen were subjected for analysis using the developed test kit. Its accuracy was measured based on the stability of DO values obtained and their correlation to the % dilution of low DO water samples. The accuracy of assay using this kit was determined to be significant at 1% and 5% level.
