OPTIMIZATION AND EFFECTS OF SOME ELECTRON ACCEPTORS ON THE PHOTOCATALYTIC DEGRADATION OF DIRECT RED 23 AZO DYE
(Sociedad Chilena de Química, 2009)
Monitoring ecotoxicity of disperse red 1 dye during photo-Fenton degradation
The present work assessed the ecotoxicity of the commercially available form of the azo dye Disperse Red 1 (DR1) and the main degradation products generated during photo-Fenton degradation. The acute toxicity tests with ...
Evaluation of the rate of abiotic and biotic degradation of oxodegradable polyethylene
The recent introduction of oxo-degradable additive in the Argentinean market has motivated the study of the effect of abiotic (temperature and ultraviolet (UV) radiation) and biotic (aerobic in compost) degradation on the ...
Poly(Ethylene Terephthalate), PET. A Review on the Synthesis Processes, Degradation Mechanisms and its Recycling
(Assoc Brasil PolimerosSao CarlosBrasil, 2009)
Studies on thermal-oxidative degradation behaviours of raw natural rubber: PRI and thermogravimetry analysis
Thermal-oxidative degradation behaviours of raw natural rubber (NR) have been investigated by using thermogravimetry analysis in inert and oxidative atmospheres and the plasticity retention index (PRI). The activation ...
Degradation of alachlor herbicide by gamma radiation from cobalt-60 in aqueous and alcohol solution
Alachlor has been widely used in agriculture all over the world. It is suggested that it may be a carcinogen and an environmental estrogen. The aim of this work was to verify the degradation the alachlor by gamma radiation. ...
Thermal degradation of geomembranes after exposure to heat
(Millpress Science Publishers, 2006-01-01)
HDPE and PVC geomembranes are sensitive to changes in their properties when in contact with high temperatures. The effects of hot temperature on polymeric geomembranes are assessed by the ASTM D794 and ASTM D5721.This paper ...
