Table 1 Iron loading estimate in the ACs after mass loss observed during thermal treatment

From: Performance assessment of activated carbon thermally modified with iron in the desulfurization of biogas in a static batch system supported by headspace gas chromatography

Sample ID	Mass loss^a (%)	Iron loading^b (mg g⁻¹)
AC3Fe	15.1	33.9
AC5Fe	72.5	104.7
AC7Fe	79.0	137.1
AC	9.89	–

^aObtained by gravimetric analysis
^bEstimated according to mass loss during thermal treatment
The initial iron content was 28.8 ± 0.20 mg Fe g⁻¹ by UV–Vis spectroscopy
