Biosorption of Sodium Dipyrone by Industrial Ash and Its Potential in Portland Cement Matrix

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

This research evaluated the use of industrial ash from eucalyptus chips in the biosorption of sodium dipyrone with the subsequent, study of its potential in Portland cement matrix. The biosorbent was characterized by the point of zero charge and the surface area. For comparison, before and after the biosorption process, scanning electron microscopy, energy dispersive x-ray spectroscopy, and Fourier transform infrared spectrometry were performed. Regarding the study of the potential of industrial ash after biosorption (AAB), it was characterized by analyzing specific mass, moisture, loss on fire, and X-ray fluorescence, as well as by X-ray diffraction, modified Chapelle, pozzolanic activity index with lime, and performance index with cement, compressive strength, and tensile strength by diametral compression. The biosorption tests were carried out in batch, it being possible to observe that at 298.15 K, 130 rpm, without pH adjustment approximately 93% of commercial dipyrone was removed. The pseudo-second-order kinetic model fitted better with the experimental data and the process was characterized as exothermic and spontaneous. The chemical composition of ash and AAB showed a predominance of CaO followed by MgO, without the presence of an amorphous halo. In the study of the filer effect, using cement pastes, both materials showed favorable results. Thus, it is concluded that the industrial ash studied has the potential to be applied as an alternative material in the removal of sodium dipyrone and for the replacement of cement in the composition of cement matrices, due to the filer effect they presented.

HIGHLIGHTS

Biosorption process of sodium dipyrone with industrial ash was efficient.

The ash after biosorption has the potential to be used as filler.

Application of the circular economy concept, with the reuse of waste in biosorption and cement replacement in cement matrices.
