Topic Information

Dear Colleagues,

Biochar is a carbon-rich material produced from pyrolysis of biomass. It has received increasing attention in recent years due to its unique structure and properties that can be used in various environmental aspects. Moreover, engineered biochar has been developed with better properties as well as for new uses. Most literature on biochar or engineered biochar deals with its use in soil for carbon sequestration, soil remediation, and soil amendment. Biochar can also be used as an absorbent for wastewater treatment. The focus of this Special Issue is the use of biochar in the adsorption of emerging contaminants. It is suggested that over one thousand types of emerging contaminants exist on earth that pose a potential threat to human health. Emerging contaminants have many different sources, including pharmaceuticals, personal care products, agricultural chemicals, lawn care products, household cleaning supplies, flame retardants, pesticides, surfactants, and industrial chemicals. Additionally, contributions are not limited to this topic, and quality research in the above-mentioned topics will be relevant for the scope of the Special Issue.

We used three purple soil (Hechuan, Jialing, and Cangxi) samples from the Jialing River basin as the research objects and added different proportions of an acid–base modified Alternanthera philoxeroides biochar (Cm) to the purple soil to study the effect of Cm on the adsorption of chlortetracycline (CTC) in the purple soil. The results indicated the following: (1) At 30 °C and pH = 6, the soil adsorption capacity increased with an increasing initial concentration of CTC. The maximum adsorption amount of CTC for each tested sample was in the range of 2054.63–3631.21 mg/kg, and the adsorption capacity in different Cm amended soils was ranked in the order of 10% Cm > 5% Cm > 2% Cm > CK. The adsorption capacity of CTC increased with an increase in the proportion of Cm. Furthermore, under the same addition ratio of Cm, Hechuan soil was found to have a better adsorption effect for CTC than Jialing and Cangxi soil. (2) The Langmuir model was the most suitable for fitting the adsorption behavior of CTC on different purple soils, and the fitting coefficients were all greater than 0.9, indicating that the adsorption of CTC on each soil sample occurred via monolayer adsorption. The thermodynamic experiment results showed that an increase in temperature was beneficial to the process of CTC adsorption, which was a spontaneous, endothermic, and entropy-adding process. (3) At pH = 6, the ionic strength ranged from 0.01 to 0.5 mol/L and the adsorption capacity of CTC of the soil samples decreased with an increase in ionic strength. In the range of pH 2–10, the adsorption capacity of CTC in all the soil samples decreased with an increase in pH. The inhibition capacity of CTC in the soil samples under acidic conditions was notably higher than that under alkaline conditions. Full article
