“…Furthermore, this approach can substantially reduce corrosion prevention expenses and mitigate environmental waste. 59,60,[623][624][625] Fruits and vegetables are recognized sources of diverse bioactive elements such as polyphenols, carotenoids, and terpenes. Extracting these beneficial biomolecules from residual products holds potential.…”

“…The slow pyrolysis of the licuri coconut husks generated four different kinds of products with a mass distribution of 36%, 40%, and 24%, between solid, liquid, and gas phase products, respectively. Although this work only focuses on the solid product, known as biochar (BC), the other products, namely the gas phase and the two liquid phases (bio-oil and pyroligneous acid) were collected and investigated for different applications as a way to propose a zero-waste process [45,46].…”

The presence of emerging contaminants in water can harm both the environment and human health. Traditional water and wastewater treatment cannot eliminate them, so different alternatives for their removal are being studied. The use of activated carbon as an adsorbent is emphasized due to its high adsorption capacity and lower cost, and to the possibility of obtaining it from biomass wastes. Thus, this study evaluated the use of Syagrus coronata waste to produce activated biochars and their adsorption capacity of isoniazid from an aqueous medium. For this, the biochar obtained through slow pyrolysis was chemically activated using two different agents, H2SO4 or KOH. The adsorbent’s acidic and textural properties were studied and correlated with adsorption behavior tested in batch and fixed-bed column systems, using commercial activated carbon as a comparison. The KOH activation process produced a predominantly microporous material (BAC), with a high surface area (1006 m2·g−1) and a high content of oxygenated functional groups (1.98 mmol·g−1). BAC outperformed all other materials tested and ones found in other works using isoniazid as a contaminant model, having a high adsorption capacity (712.42 mg·g−1). Thus, this work successfully obtained an efficient adsorbent produced from an agro-industrial waste, with superior performance.
