“…The Langmuir and Freundlich constants obtained are reported in Table 3, where they are compared with the same parameters calculated for other bio-adsorbent materials reported elsewhere. The comparison shows that YM has a higher adsorption capacity (q max ) than most of the other bio-adsorbents, such as chaff [43], peanut hull [44], banana peel [45], orange peel [45], rice husk [46], apricot shells [47], wheat shells [48], spent coffee grounds [49] and passion fruit waste [50]. Only the study conducted by Uddin et al on tea wastes [51] reveals a higher adsorption capacity than yerba mate, which was also promoted by the high specific surface area of the particles adopted in the adsorption tests (180-300 µm) compared to the material tested in the present study.…”

Yerba mate (Ilex paraguarensis, YM) was used as biomaterial for the removal of anionic and cationic compounds from wastewater. Chromium hexavalent Cr(VI), Remazol brilliant blue (RBB) and methylene blue (MB) were selected as pollutants. A calcination step was performed after the washing and drying steps to evaluate its effectiveness at increasing the adsorption capacity of the solid. Both YM and calcinated YM (CYM) were characterized by means of scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR) and Brunauer–Emmett–Teller (BET) analysis. Adsorption batch tests revealed that YM was ineffective for the removal of Cr(VI) and RBB, while good results were obtained for MB (up to 80%) without pH dependency of the adsorption process, and CYM was able to remove Cr(VI) (up to 77%) and RBB (up to 65%) but not MB. The adsorption isotherm of MB on YM at 298 K was obtained experimentally and it is well represented by the Langmuir isotherm. YM’s adsorption capacity for MB was estimated to be 59.6 mg/g. Kinetic batch tests were conducted and the experimental results were fitted with a mathematical model. The low influence of temperature compared to the influence of the YM concentration on the adsorption rate was explained.

“…Promising from economic point of view of environmental protection is the use of secondary plant wastes as sorbents for solving environmental problems. In the raw form, such materials are characterized by low absorption properties [8]. The most common technique for processing a solid shell of the fruit and berry seeds is to carbonize it at high temperatures to obtain carbon sorbent materials [9].…”
