Déchets industriels Résumé : The components of liquid radiography waste may be harmful or useful, depending on the composition of the raw material. This paper aims to remove the hazardous content from liquid radiography waste, while recoving the silver nanoparticles. The microwave plasma method was adopted to achieve this purpose. First, the conventional microwave oven was modified to generate the plasma in 100 mL liquid radiogrpahy waste at 500W. The plasma generation time was varied for 1, 3, 4, 7, and 10 min. In the treated liquid, the total suspended solid (TSS) was analyzed through ultraviolet spectrophotmetry, the silver (Ag) was examined through atomic absorption spectrophometory, and the biological oxygen demand (BOD) and chemical oxygen demand (COD) were discussed by titration method. In addition, the recovered silver was identified by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the microwave plasma method reduced the TSS by 99.36 %, the Ag by 92.73 %, the pH by 3.42 %, the BOD by 57.13 %, and the COD by 57.14 % ; In addition, spherical shaped silver nanoparticles were indentified at some peaks with average crystallite size ranging from 2.64 nm to 65.64 nm. The research findings shed important new light on the recycling of liquid radiography waste.
