Development of Techniques for Detection of Low Molecular Weight Contaminants in Product Water from Water Purification or Water Re-Use Systems.

摘要

A permanganate colorimeter instrument to monitor the quality of MUST product water has been developed and successfully tested at the breadboard level. During the program it was demonstrated that (1) aldehydes are the last of the constituents of MUST RO permeate to be ozonated, (2) residual MUST aldehydes (principally acetaldehyde) rapidly reduce permanganate solutions, and (3) the degree of permanganate reduction may be easily quantitated colorimetrically and is directly proportional to residual MUST water contamination. The colorimeter and required hardware is judged low-cost, rugged, simple, and reliable. (Author)
