Impurities and forced degradation studies: A review
(2016-01-01)
The safety of pharmaceuticals is dependent not only on the intrinsic toxicological properties of the active ingredient, but also on the impurities and degradation products that it may contain. The presence of impurities ...
Stability study and degradation kinetics of ceftazidime in pharmaceutical preparations
(Scientific & Academic Publishing, 2012)
Stability study of ceftazidime was realized in order to investigate kinetics of degradation of this drug both in powder for injection and reconstituted sample. Ceftazidime was submitted to conditions of accelerated thermal ...
SnO(2)-based materials for pesticide degradation
(ELSEVIER SCIENCE BV, 2010)
This study presents the results of the degradation of the pesticide atrazine using electrochemical and photo-assisted electrochemical degradation techniques using SnO(2)-containing electrode of nominal composition electrodes ...
Polycyclic aromatic hydrocarbons degradation by marine-derived basidiomycetes: optimization of the degradation process
(2018-01-01)
Pyrene and benzo[a]pyrene (BaP) are high molecular weight polycyclic aromatic hydrocarbons (PAHs) recalcitrant to microbial attack. Although studies related to the microbial degradation of PAHs have been carried out in the ...
New thermal study of polymerization and degradation kinetics of methylene diphenyl diisocyanate
(2018-09-01)
This work investigates the thermal polymerization process of a methylene diphenyl diisocyanate (MDI) monomer as well as its thermal degradation following the ICTAC recommendations. MDI monomer is widely used as a synthetic ...
Vocal responses of austral forest frogs to amplitude and degradation patterns of advertisement calls
(Elsevier, 2017)
Degradation phenomena affecting animal acoustic signals may provide cues to assess the distance of emitters.
Recognition of degraded signals has been extensively demonstrated in birds, and recently studies have also
reported ...
Photo-assisted electrochemical degradation of real textile wastewater
(I W A PUBLISHING, 2010)
In the present study, photo-assisted electrochemical degradation of real textile wastewater was performed. Degradation assays were performed at constant current (40 mA cm(-2)) in a combined electro/photochemical flow-cell ...
Study of photo-assisted electrochemical degradation of carbaryl at dimensionally stable anodes (DSA (R))
(ELSEVIER SCIENCE BV, 2009)
This paper presents the results concerning the degradation of the pesticide carbaryl comparing two methods: electrochemical (EC) and photo-assisted electrochemical (PAEC). The experimental variables of applied current ...
TRIBROMOPHENOL DEGRADATION BY A CATECHOL-DRTVEN FENTON REACTION
(Sociedad Chilena de Química, 2009)
Studies on thermal-oxidative degradation behaviours of raw natural rubber: PRI and thermogravimetry analysis
(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 ...
