ABSTRACT:
Waste water from the preparation of salts of dithiocarbamic acid is detoxified by acidifying the waste water to promote hydrolytic decomposition of organosulfur compounds, passing an inert gas through the acidified water to aid in expelling decomposition gases thereby increasing the decomposition rate, and, optionally, adjusting the pH of the resulting solution toward neutral.
