Enhancement effect of potassium ferrate on self-activation: Significant improvement in pore structure and adsorption performance of activated carbon.

This work developed a method using bamboo shoot shells as raw material to produce Fe-modified ACs combining self-activation and chemical modification. Adding small amounts (0.5-5 %) of KFeO accelerated the pyrolysis process and CO release, and reduced the activation energy and temperature of self-activation reaction.

The Ash-Forming Element Migration and Mineral Transformation during the Bamboo Combustion Process.

To investigate the effect of combustion temperatures on element transformation of ash, bamboo was fired using a muffle furnace at 550, 600, 700, 800, 900, and 1000 °C. Chemical compositions, micromorphology, and mineral and thermal behavior of ash were characterized. The main components included KO, SiO, PO, MgO, and CaO at a temperature of 550 °C.

Effect of Deashing Treatment on Ash Fusion Characteristics of Biochar from Bamboo Shoot Shells.

To investigate the influence of deashing on fusion characteristics, a combined method of water and acid washing with different sequences (water washing followed by acid washing, and acid washing followed by water washing) was used to treat the biochar of bamboo shoot shells (BBSSs). The results show that deashing decreased the K content of the biochar from 50.3% to 1.

Interference between di(2-ethylhexyl) phthalate and heavy metals (Cd and Cu) in a Mollisol during aging and mobilization.

Diffuse pollution of the soil by phthalates and heavy metals causes numerous concerns. Their respective fates when coexisting require further investigation. In this study, di(2-ethylhexyl) phthalate (DEHP) and Cd/Cu were used as subjects, focusing on their behavior in Mollisols under combined pollution based on their concentration, fractionation, and leaching.
