Sequential spectrofluorimetric determination of free and total glycerol in biodiesel in a multicommuted flow system
(SPRINGER HEIDELBERG, 2011)
A new procedure for spectrofluorimetric determination of free and total glycerol in biodiesel samples is presented. It is based on the oxidation of glycerol by periodate, forming formaldehyde, which reacts with acetylacetone, ...
Solvent-free heteropolyacid-catalyzed glycerol ketalization at room temperature
(Royal Society of Chemistry Advances, 2019)
Zeolitic core@shell adsorbents for the selective removal of free glycerol from crude biodiesel
(Wiley VCH Verlag, 2015-06)
Selective adsorption of free glycerol from crude biodiesel was investigated by using mesoporous silica spheres coated with a thin shell of microporous silicalite-1. A polycrystalline silicalite-1 shell was formed upon first ...
Determination of free glycerol in biodiesel at a platinum oxide surface using potential cycling technique
(Elsevier B.V., 2009-06-30)
A novel, inexpensive and fast method based on the electrooxidation of glycerol on platinum electrodes by the potential cycling technique has been designed for the determination of free glycerol in biodiesel. A wide range ...

Hepatic glycerol metabolism is early reprogrammed in rat liver cancer development
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-03)
Evidence shows that oral glycerol supplementation during the early stages of rat liver cancer reduces the growth of preneoplastic lesions. Besides, human hepatocellular carcinoma (HCC) cells display decreased expression ...
Nanozeolites as support for laccase immobilization: Application to mediated glycerol oxidation
(2021-09-25)
This study investigated the use of nanozeolites as support for laccases from P. ostreatus (LPO), Aspergillus sp (LAsp) and A. bisporus (LAB) immobilization applied to 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) mediated ...
Free Glycerol Sensing in Biodiesel: Automatic System Based on Sequential Enzymatic Reactions Using a Fit-for-Purpose Chemiluminescence Detection Chamber
(American Chemical Society, 2019-10)
The transesterification reaction to produce biodiesel generates a residual content of free glycerol, which may cause several problems to the engines. According to the international specification, the free glycerol determination ...
A flow injection procedure based on solenoid micro-pumps for spectrophotometric determination of free glycerol in biodiesel
(ELSEVIER SCIENCE BV, 2010)
A flow system designed with solenoid micro-pumps is proposed for fast and greener spectrophotometric determination of free glycerol in biodiesel. Glycerol was extracted from samples without using organic solvents. The ...
