Title: Insolubilization of heavy metals in Municipal Solid Waste Incineration fly ash by
geopolymer solidification using akadama soil
Presenters: ○SEKINO Rina, UMEZAWA Yuuki, MATSUDA Wataru, KOIKE Yuya
Research focus: Municipal solid waste incineration fly ash is expected to serve as a resource, and it is necessary to examine separation and extraction technologies for trace metal elements, including rare metals, contained in the fly ash. Therefore, an elemental composition analysis of municipal solid waste incineration fly ash was conducted, and referring to the pH-dependent testing methodology of the Japan Society of Material Cycles and Waste Management, an attempt was made to separate and extract trace metal elements by gradually adjusting the pH of the leachate. It is believed that the high evaluation was due to the development of a simpler method for separating trace metal elements, aiming at resource reuse.
