Studies of Detergent Systems useful in Treatment of Bilge Water and other Sewage Disposal Systems.

摘要

Ultra-violet spectroscopy has been used to study systems of a non-ionic detergent in synthetic sea water,and in cyclohexane,in concentrations of between 100and 300ppm,as well as mixtures of the detergent and (a) Navy Distillate Fuel Oil; (b) Turbine Extreme Pressure Lube Oil;and (c) a Light lubricating oil,in cyclohexane solution and in synthetic sea water. The detergent solutions were found to show absorbance peaks at 280mu and 277.5mu,to obey Beer's law,and the quantity of detergent present could be related to the absorbance at these peaks. However,in the oil/detergent mixed solutions,while the detergent showed peaks at 284mu and 272.5mu,and thus could be qualitatively identified,the absorbance of oil and detergent were not quantitatively additive,and thus the detergent could not be quantitatively determined in the presence of the oils.
