“…In the process of biochar adsorption of microorganisms, the hydrophobic force and electrostatic force come in handy for important purposes. Among them, the adsorption of bacteria went through the six processes of flocculation, surface adsorption, carrier covalent bonding, cell cross-linking, and gel sealing and carrier immobilization (Tao et al 2020). After the action of biochar with T. ferrooxidans, the peak at 630 cm −1 belonged to the stretching vibration of SO 4 2− , and the peak at 514 cm −1 belonged to the FeO 6 regular octahedral vibration, which was caused by the adsorption of jarosite precipitates formed by the oxidation of Fe 2+ by T. ferrooxidans in the bacterial solution to the surface of the biochar (Wang et al 2017).…”

Among the many extraction technologies for recovering metal resources from tailings, bioleaching technology is gradually showing its momentum. In our research, the enhanced effect of biochar on the bioleaching of stone coal tailings by Thiobacillus ferrooxidans (T. ferrooxidans) has been explored. In the static bioleaching experiment for 10 days, the leaching rate of vanadium (V) and copper (Cu) increased by 26.8% and 21.0% respectively after adding 5 g/L biochar. The dynamic bioleaching experiment further verified that under the promotion of biochar, the 44 day cumulative leaching rate of V and Cu increased by 15.3% and 14.5%, respectively. The promoting effect of biochar on T. ferrooxidans was mainly reflected in two aspects. The unique porous structure of biochar created a microenvironment for free microorganisms for inhabitation, while storing abundant nutrients. Biochar can also act as an excellent electronic medium to promote electron transfer, improving the oxidation ability of T. ferrooxidans on Fe 2+ . Furthermore, the presence of biochar may effectively inhibit the formation of jarosite precipitation on tailings in bioleaching, thereby improving the dissolution of tailings and the release of metal elements. This study demonstrates that biochar-enhanced bioleaching may be an efficient and environmentally friendly method for recovering metal resources from tailings.

“…Atrazine is one of the most commonly used agricultural herbicides and is effective in preventing weeds, predominantly in corn, sorghum, and sugarcane crops (Tao et al, 2020). It is considered toxic to aquatic organisms, plants, and humans because it is moderately mobile and has a long half-life, high leaching potential and high chemical stability (Zhang et al, 2018;Gao et al, 2019).…”

Adsorption of Atrazine in Rice Husk Biochars: A Phenomenological Model Applied to Equilibrium and Kinetic Studies

et al. 2022

Atrazine is an herbicide used to remove weeds in agricultural crops; however, because it is considered toxic, options for removing it from the environment are needed. Adsorption on biochar is an efficient technique for removing organic contaminants. In this study, the atrazine adsorption capacities of two biochars (BCA400 and BCA700) produced from rice husks at different pyrolysis temperatures (400 and 700 °C) were compared by phenomenological modeling. The biochars were characterized by SEM, FTIR and BET. Experimental kinetic and equilibrium data were obtained to evaluate Langmuir, Freundlich and BET isotherms and to conduct intraparticle diffusion. In comparison to BCA400, BCA700 showed a higher adsorption capacity at a higher pyrolysis temperature, and the Freundlich isotherm best described its system. To describe the kinetic adsorption data for the biochars, a phenomenological model based on intraparticle diffusion was applied, and the model fit well to these data for each biochar. This model is slow and involves the transport of atrazine to the pores of the biochar. Thus, the predictive model can be scaled up to adsorption systems.
