Additional steps in mechanical recyling of PET
(Elsevier B.V., 2010-01-01)
This study presents the laboratory scale results of an extra step in Poly (ethylene terephthalate) - PET mechanical recycling (grinding, washing, drying and reprocessing): a chemical washing after the conventional one. ...

Lipase activity of resting cells of Aspergillus flavus after solvent washing; memory effects from endogenous substrate arising from the original growth medium
(2000)
Aspergillus flavusresting cells were washed with solvents of different polarity for 2, 6, and 24 h and then suspended in isooctane containing either oleic acid and 1-propanol or 1-propanol alone. Propyl oleate and propyl ...
High performance purification process of methyl and ethyl esters produced by transesterification
(Elsevier, 2013-07)
The aim of this work is the obtention of high quality methyl and ethyl esters, particularly in those cases in which conventional purification procedures fail such as in the production of ethylesters or in the case of ...
Statistical analysis of the influence of synthesis conditions on the properties of hierarchical zeolite Y
(Elsevier, 2021-06)
Commercial zeolite USY (CBV500, Si/Al = 2.6) was dealuminated with oxalic acid, desilicated with ammonium hydroxide assisted by cetyltrimethylammonium bromide, and acid washed with lactic acid for obtaining hierarchical ...
Modelling changes in anthocyanins, total vitamin C, and colour as a consequence of peracetic acid washing disinfection of two cultivars of strawberries for fresh-cut processing
(Wiley, 2013-05)
The aim of the study was to quantify and model the retention of total anthocyanins (TAR), ascorbic acid (AAR) and total vitamin C (Vit C), and the colour changes of fresh-cut strawberries after washing disinfection with ...
Effects of organic and inorganic additives on flotation recovery of washed cells of Saccharomyces cerevisiae resuspended in water
(Elsevier B.V., 2006-03-01)
Separation of microbial cells by flotation recovery is usually carried out in industrial reactors or wastewater treatment systems, which contain a complex mixture of microbial nutrients and excretion products. In the present ...
