Characterization and thermal study of organic extracts of urban solid waste
(2014)
The urban residues put in landfill of the city of Sa˜o Carlos-SP, Brazil, in 2004 represent 58.7 % of decomposed organic material. The aim of this research was to characterize samples of urban solid waste and its organic ...
Aqueous-Organic Biphasic Systems. Extraction of organic compounds
(Elsevier, 2020)
Liquid-liquid extraction (LLE) is a method of separation based on the distribution of a compound between two essentially immiscible solvents. Extraction procedures are carried out for two main reasons. An exhaustive ...
An alternative methodology for the extraction of humic substances from organic soils
(1998-12-01)
The present study reports on an alternative methodology for the extraction of Humic Substances (HS) from the soil. The extractions were carried out with 0.5 M KOH for 3 h, at a ratio of 1:20 (m/v) under a nitrogen atmosphere. ...
