Abstract
Diapers are reusable waste. This research presents physicochemical properties of sodium polyacrylate in new (ND) and used (UD) diapers, via wavelength-dispersive X-ray fluorescence (WDXRF), Fourier transform infrared (FTIR), X-ray diffraction (XRD), pH, turbidity and colour. Additional constituents detected in ND, while others were slightly higher in UD. Slight decrease (2000�2500 cm?1, UD) and bulk peaks (3287�3333 cm?1, UD) were observed and functional group at 2897 cm?1 (ND) disappeared showing their role as absorption sites. The pH (6.83�8.50), turbidity (16.3�36.6 NTU) and colour (153�432 Pt.Co) values were obtained. Thus, this provides a baseline reference for diapers application in concrete technology. � 2021 Elsevier B.V.
