Simplified Laboratory Procedures for DO (Dissolved Oxygen) Determination (ALPHA/AWWA/WPCF Method)

摘要

Under sponsorship of Water Pollution Control Federation, the laboratory procedures for DO determination as outlined in the 15th and 16th editions of the APHA/AWWA/WPCF Standard Methods for the Examination of Water and Wastewater was simplified by the WPCF Simplified Laboratory Procedures Task Force (Mr. H. Timothy Neketin, Chairman) for use by the waste treatment plant operators. Dr. Lawrence K. Wang's DO Model is introduced for practical application. The U.S. EPA recommended phenylarsine oxide (PAO) is also accepted as an alternative to the sodium thiosulfate in DO determination.
