Ozonation of pentylacetate contaminated waters from textile care industry
In this article the use of ozone for the treatment of pentylacetate contaminated waters is evaluated. Pentylacetate has started to be used in the drycleaning process as a new solvent due to its economic benefits. However, in the technical literature experimental data involving pentylacetate ozonatio...
