Polyamidoxime and graphene oxide synergistically stabilized foam decontaminant for removal of radioactive surface contaminants.

In this study, polyacrylonitrile was modified to polyamidoxime to enhance foam stabilization and decontamination rate. Polyamidoxime was combined with graphene oxide, 1 wt% of saponins, and 1 wt% of alkyl glycosides to formulate the PAO/GO foam decontaminant. The outcomes demonstrated resulted in the half-life of the foam extending from 32 to 308 min. The PAO/GO foam decontaminant displayed α-ray decontamination rates of 93.30%, 98.34%, and 99.81% on stainless steel, tile, and glass surfaces. Hence, the dual functional PAO/GO in stabilizing foam while enhancing decontamination rates underscores its potential for radioactive decontamination. [ABSTRACT FROM AUTHOR]
