Abstract
ABSTRACT
One of the major difficulties experienced when solidifying organic waste is the volatilization of organic compounds during mixing and curing. The occurrence of volatilization has made solidification's ability to reduce organic waste leachability suspect. This paper recounts the ability of organoclays to reduce the volatilization of nitrobenzene (NB) and 1,2-dichlorobenzene (DCB) from cement-based solidification samples. The results indicated the incorporation of organoclays reduced the volatilization caused by cement-based solidification of NB and DCB to 1/6 and 1/10 of their original values, respectively. The samples utilizing the organoclays retained the majority of NB and DCB added to them, 65-100% and 63-94%, respectively. The ability of organoclays to reduce volatilization appeared to be inversely correlated to their increasing percent organic matter content.
