The global environmental issue of arsenic (As) contamination in drinking water is a significant problem that requires attention. Therefore, the aim of this research was to address the application of a sustainable methodology for arsenic removal through mycoremediation aerated with micro-nanobubbles (MNBs), leading to bioscorodite (FeAsO4·2H2O) generation. To achieve this, the fungus Trichoderma atroviride was cultivated in a medium amended with 1 g/L of As(III) and 8.5 g/L of Fe(II) salts at 28 °C for 5 days in a tubular reactor equipped with an air MNBs diffuser (TR-MNBs). A control was performed using shaking flasks (SF) at 120 rpm. A reaction was conducted at 92 °C for 32 h for bioscorodite synthesis, followed by further characterization of crystals through Fourier–Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and X-ray diffraction (XRD) analyses. At the end of the fungal growth in the TR-MNBs, the pH decreased to 2.7–3.0, and the oxidation-reduction potential (ORP) reached a value of 306 mV at 5 days. Arsenic decreased by 70%, attributed to possible adsorption through rapid complexation of oxidized As(V) with the exchangeable ferrihydrite ((Fe(III))4-5(OH,O)12), sites, and the fungal biomass. This mineral might be produced under oxidizing and acidic conditions, with a high iron concentration (As:Fe molar ratio = 0.14). The crystals produced in the reaction using the TR-MNBs culture broth and characterized by SEM, XRD, and FTIR revealed the morphology, pattern, and As-O-Fe vibration bands typical of bioscorodite and römerite (Fe(II)(Fe(III))2(SO4)4·14H2O). Arsenic reduction in SF was 30%, with slight characteristics of bioscorodite. Consequently, further research should include integrating the TR-MNBs system into a pilot plant for arsenic removal from contaminated water.

“…These minerals might have contributed to arsenic removal through adsorption-precipitation processes. Reports by Vega-Hernández (2021) [ 44 ] and Ramirez-Castillo et al (2023) [ 19 ] have discussed solid precipitation. In the SF culture, solid formation occurred and obtained 30% of arsenic removal at day 5.…”

“…The existing technologies of arsenic removal in water include co‐precipitation (Nur et al, 2019; Park et al, 2016), ion exchange (Lee et al, 2017; Olah et al, 2017; Ortega et al, 2017), oxidation–reduction method (Cheng et al, 2016), ultrafiltration (Kumar et al, 2019), coagulation filtration, biological method (Vega‐Hernandez et al, 2021), adsorption method, and so on. The adsorption method is one of the most commonly used methods to remove arsenic pollution in water due to its advantages, including simple and easy operation, high treatment effect, low cost, and various adsorbents (Uddin, 2017).…”

Fe-Mn binary oxide (FMBO) is a promising adsorbent for As(III) removal through combined adsorption and oxidation. The calcined oyster shellsupported Fe-Mn binary oxide (FMBO/OS) adsorbent was synthesized by the co-precipitation method. Results indicated that the calcined oyster shell, as a carrier, improved the stability of FMBO and its adsorption capacity for As(III). The maximum adsorption capacity of FMBO/OS on As(III) reached 140.5 mgÁg À1 . Under pH 5.0 and 25 C, the removal efficiency of FMBO/OS to As(III) solution (C 0 = 10 mgÁL À1 ) reached 87% within 12 h. Moreover, based on the characterization analyses, the removal mechanisms of As(III) were deduced to include the combined adsorption and oxidation process of FMBO and the synergistic effect of oyster shells. This work provides new insights into synthesizing efficient and green adsorbents to remove aqueous As(III). Meanwhile, it provides technical support for reusing waste biomass materials such as the oyster shell. Practitioner Points• FMBO/OS was prepared by a simple hydrothermal co-precipitation method.• The carrier alleviates the agglomeration of Fe-Mn oxides.• The adsorbent shows a strong adsorption capacity of As(III) and good selectivity.• The good results benefit from the synergistic effect of calcium arsenate generation.• The prepared adsorbent can adsorb arsenic in real samples.
