Monitoring ecotoxicity of disperse red 1 dye during photo-Fenton degradation

Universidade Estadual Paulista (UNESP); Universidade de São Paulo (USP); Universidade Estadual de Campinas (UNICAMP) (2016-04-01)

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

Portillo, Florencia Soledad; Yashchuk, Oxana; Hermida, Elida Beatriz (Elsevier, 2016-08)

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 ...

Romao, W; Spinace, MAS; De Paoli, MA (Assoc Brasil PolimerosSao CarlosBrasil, 2009)

Degradation analysis of the SnO2 and ZnO-based varistors using electrostatic force microscopy

Ramírez, M. A.; Tararam, R.; Simões, A. Z.; Ries, A.; Longo, Elson; Varela, José Arana (2014)

Studies on thermal-oxidative degradation behaviours of raw natural rubber: PRI and thermogravimetry analysis

Universidade Federal do Rio de Janeiro (UFRJ); Universidade Estadual Paulista (UNESP); Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) (2013-10-01)

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

SILVA, M. P. da; VIEIRA, E. M. (SPRINGER, 2009)

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

Universidade Estadual Paulista (UNESP) (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 ...
