Hydrothermal oxidation of organochlorines

Hydrothermal Oxidation of Fecal Sludge: Experimental Investigations and Kinetic Modeling

Hydrothermal oxidation (HTO) provides an efficient technique to completely destroy wet organic wastes. In this study, HTO was applied to treat fecal sludge at well-defined experimental conditions. Four different kinetic models were adjusted to the obtained data. Among others, a distributed activation energy model (DAEM) was applied. A total of 33 experiments were carried out in an unstirred bat...

Supercritical water oxidation of recalcitrant compounds under a hydrothermal flame

Supercritical water oxidation (SCWO) is able to completely mineralize every kind of waste in residence times lower than one minute. Supercritical water oxidation in presence of hydrothermal flames can reduce residence times to the order of milliseconds. The most recalcitrant compounds in terms of difficulty to oxidation for the supercritical water oxidation are acetic acid and ammonia. The obje...

The oxidation state of hydrothermal systems on early Enceladus

Organochlorines and endometrial cancer risk.

There is concern that persistent environmental pollutants such as dichlorodiphenyltrichloroethane (DDT) and polychlorinated biphenyls (PCBs) increase breast cancer risk, at least partially through estrogenic effects. Because the endometrium is more sensitive to estrogenic stimulation than the breast, such a carcinogenic effect should be more pronounced in the endometrium than the breast. In a p...

Application assessment of α-Tocopherol in conservation of historical cotton fabrics against hydrothermal oxidation by using accelerated-aged samples

the importance of textile historical works is not hidden from anyone In the field of preservation and restoration of historical and cultural objects. due to the organic structure of cellulose, Historical cotton fabrics are exposed to spontaneous oxidation and the degradation process will not stop even in an isolated environment. Keeping such sensitive works in the unfavorable conditions of the ...
