| Аннотация |
Spent cutting fluids (coolant) are formed from the activity of
metal processing, as a result of contamination and biodefeat of
the emulsion. For disposal of spent coolant, vacuum
distillation and reagent decomposition methods are used, but
membrane separation methods are the most effective and
environmentally friendly. In the process of separation of spent
coolant by membrane methods, a concentrate is formed
consisting of petroleum products (NP), fats, surfactants. Using
the method of high-performance liquid chromatography using
a light scattering detector, the content of fatty acids in the
concentrate of fresh and spent cutting fluid obtained from a
3% emulsion using a dynamic membrane with a polystyrene
surface layer was studied. The calibration dependence of the
fatty acid content from 2 mg / dm3 to 8 mg / dm3 is
established. It has been shown that fatty acids such as palmitic
and stearic, along with petroleum products, have a negative
effect on aquatic ecosystems. The experimental conditions for
the quantitative analysis of fatty acids, in particular, the
parameters of calibration graphs, are determined. It was found
that the concentration of stearic acid in spent coolant exceeds
the maximum permissible concentration for fishery waters by
14,000 times. Due to the high content of oil products, the
concentrate obtained can be used as heating oil or an
inhibitory additive to protect pipelines from the corrosive
effects of produced water. |
