Thermal desorption of HCH [PDF]

Journal of Thermal Analysis and Calorimetry, 2015
To evaluate the effectiveness of the thermal remediation of soil decontamination, samples containing organochlorine insecticide hexachlorocyclohexane (HCH) were subjected to different temperatures depending on the exposure time. For this study, reference material and technical grade HCH were heated separately at β = 1 and 10°C min-1 in a ...
