To investigate the potential of activated carbon from palm kernel shell waste for Tc-radiolabeled nanocarbon aerosol, a new production technology for carbon-based Tc-radioaerosol from such a waste was developed. Treated-palm shell charcoal (t-PSC) was prepared by hydrothermal method to increase the surface area, followed by Tc radiolabelling optimization. The optimal Tc radiolabeling conditions resulted in an adsorption capacity of 21.43 ng Re/g t-PSC (8.32 GBq Tc/g t-PSC). After high-energy milling treatment, fines particle fraction (FPF), and median mass aerodynamic diameter (MMAD) of the milled t-PSC were 28.34 ± 0.61%, and 8.31 ± 2.31 μm, respectively. The results imply that Tc-labeled t-PSC has a potential for lung ventilation scan agents with the optimization of milling process to reduce the aerodynamic size within the optimal lung delivery of less than 5 μm.

Article Synopsis
- Cadmium contamination in aquatic systems is a major environmental issue, and this study introduces a new hybrid material called Fe-TWBC, made from combining solid waste iron tailings and biochar through co-pyrolysis.
- Characterization analyses indicated that the metal oxides from iron tailings were effectively integrated into the biochar, enhancing its surface functionality.
- The Fe-TWBC demonstrated a significantly higher capacity for cadmium adsorption (95.06 mg·g) compared to both pristine biochar and iron tailings, and adsorption behavior was consistent with established kinetic and isotherm models, showcasing its potential for environmental cleanup and sustainable waste utilization.

To investigate the remediation effect of iron-manganese-modified biochar from different biomasses （FM-BC） on Cd-contaminated alkaline soil, FM-BC was prepared using branches of , durian shells, and corn stalks. The characteristics of FM-BC, the adsorption of Cd（Ⅱ） in water, and the available, fraction of Cd in alkaline soil were studied using bath adsorption and soil culture experiments. The results showed that the specific surface area, total pore volume, and oxygen content of FM-BC were significantly improved.

Compared to the laboratory preparation of biochar, there is less research on the adsorption of antibiotics by industrial production of biochar in water. In this study, three types of industrial production biochar （peanut shell biochar, sludge biochar, and perishable waste biochar） were selected, and their adsorption performance for tetracycline in composite-polluted water was systematically studied. The results indicated that the Freundlich equation could well fit the adsorption isotherms of the three types of biochar for tetracycline.

Organic pollutants, especially dyes, are seriously hazardous to the aquatic system and humans due to their toxicity, and carcinogenic or mutagenic properties. In this study, a biochar prepared from agricultural waste (pecan shells) via pyrolysis was applied to remove the dye pollutant Congo Red from wastewater to avoid a negative effect to the ecosystem. This study also investigated the effect of preparation conditions (temperature and heating rate) on the physicochemical properties and the adsorption performance of biochars.
