Abstract EN
The study aimed at evaluating the humic substances (HSs) content from municipal solid waste incinerator (MSWI) bottom ash and its variation with time and the effect of temperature on HSs formation.
The process suggested by IHSS was applied to extract HSs from two different bottom ash samples, and the extracted efficiency with NaOH and Na4P2O7 was compared.
MSWI bottom ash samples were incubated at 37∘C and 50∘C for 1 year.
HSs and nonhumic substances were extracted from the bottom ash sample with different incubated period by 0.1 M NaOH/Na4P2O7.
Results show that the rate of humic acid formation increased originally with incubation time, reached a maximum at 12th week under 37∘C and at 18th week under 50∘C, and then decreased with time.
More humic acid in MSWI bottom ash was formed under 50∘C incubated condition compared with that incubated under 37∘C.
Also, the elemental compositions of HSs extracted from bottom ash are reported.
