desorption contamination heavy metals isotherm single- and multi-metal solutions
2015/3/10
The aim of this study was to evaluate and compare the competitive and individual sorption of Cd, Cu, Pb and Zn on three natural soils: a Gleyic Fluvisol (content of Cd 30, Cu 25, Pb 2297 and Zn 3718 m...
Spectroscopic characteristics of humates isolated from different soils
SFS and UV-VIS spectroscopy soil humic substances
2015/3/3
Spectral characterisation of soil humic substances is one of the important methods for their quality identification. In this work, two optical methods (UV-VIS and SFS) were used. The absorbance in the...
