(DTPA) extraction followed by atomic absorption; Fe, Mehlich I extraction with atomic absorption; Ca2+ and Mg2+, KCl (0.1 M) extraction followed by the complexometric titration method (EDTA method); Al3+, KCl (0.1 M) extraction followed by titration with NaOH; S, Ca2P...
The minerals content of K, Ca, Na and Mg were determined by a flame atomic absorption spectrophotometer (FAAS) (M6, Termo Elemental, Waltham, MA, USA), respectively. The content of Fe and Cd in digestion solution were measured by inductively coupled plasma mass spectrometry (ICP-MS, Thermo ...
Brasquet and Cloirec [31] observed that the main resistance to the mass transfer for adsorption on ACFs might be due to the diffusion through micropores within the ACFs and the effect of the external mass transfer was insignificant. The objective of this study was to investigate the break...
