Organic geochemistry of sewage sludge. I. Lipid fractionation by thin layer chromatography

Lipid Analysis by Quantitative Thin-layer Chromatography.

Fractionation of Cholesterol Esters by Thin-layer Chromatography.

Identification of some lipid peroxides by thin-layer chromatography.

Solvent systems are described which permit class separations of various peroxidized lipids by thin-layer chromatography. This procedure has proved useful in biological studies and for testing the deterioration of lipids. Proof is given that the least polar peroxides of methyl esters, glycerides, and fatty acids are monoperoxides; it is then assumed that the least polar peroxides in the other te...

Sewage Sludge Biochar: Physicochemical Properties and Fractionation of Zinc and Lead Metals

One of the significant factors affecting biochar properties is the pyrolysis temperature. This study aimed to investigate the effect of pyrolysis temperature on the properties and fractionation of Zn and Pb in biochars produced by sewage sludge. Biochars were prepared at temperatures of 300 to 700 °C and the physicochemical properties, availability, and fractionation of Zn and Pb were investiga...

Fractionation of naturally occurring lecithins according to degree of unsaturation by thin-layer chromatography.
