摘要: Abstract Stable isotopes were used to constrain the origin of CO2 involved in ageing process municipal solid waste incineration (MSWI) bottom ash under open-air conditions. The δ13C and δ18O values CaCO3 occurring MSWI samples variable age residual organic matter content measured, laboratory assessments made isotopic fractionation accompanying neo-formation during accelerated carbonation experiments or pure lime with atmospheric industrial CO2. results indicate that stable compositions exhibited by fresh aged reflect non-equilibrium processes resembling those described concrete mortar. They also lead conclusions on prevalent involvement ash.
