Density functional theory study on the microscopic mechanism of NO2 adsorption and reduction by potassium-doped biochar: the key role of the active sites Tong Hao Qian Zhou Dongni Shi Original Research Open access 01 April 2025 Article: 67 Invertebrate community responses to biochar addition in...
Sugarcane bagasseAdsorptionIsothermChitosanEngineered biochar.Today, to reduce the risks of contaminants, new remediation techniques have been focused on low-cost and environmentally friendly manners. Given the frequency of access, inexpensiveness and good physical and chemical properties, biochar has a ...
Reactivation (regeneration) of biochar after the adsorption process to be used for several cycles reduces the operational and running cost of the wastewater treatment process significantly. In other words, adsorbent’s high recycling and reuse are critical for wastewater management’s economic efficiency...
adsorption ability and some even released NO 3 2 into water solution. These contradictory results are likely because of the differences in properties among the biochars, which poses an urgent need to disclose the relationship between biochar characteristics and their effects on adsorption of NH 4 +...
(0.9392) was higher than those of the pseudo-first-order model (0.4544). The same was observed to progesterone: a rapid phase of adsorption in the first 45 min and a second phase of equilibrium. On the other hand, R2of the pseudo-first-order model (0.8651) was higher than those of ...
With social progress and industrial development, heavy metal pollution in water and soils environment is becoming more serious. Although biochar is a low-cost and environmentally friendly adsorbent for heavy metal ions, its adsorption and immobilization efficiency still need to be improved. As an upgra...
Biochar is characterized by large pore surface area. Hence it has a large number on nonfuel use such as adsorption of chemicals and carbon storage in ground. View chapter Book 2018,Biomass Gasification, Pyrolysis and Torrefaction (Third Edition) ...
The ability of biochars to adsorb NH4(+)-N followed: C-BC>P-BC>W-BC, and the adsorption amount decreased with higher pyrolysis temperature. The ability of C-BC to sorb NH4(+)-N was the highest because it had the largest cation exchange capacity (CEC) among all biochars (e.g., C-...
A two-stage intra-particle diffusion model, limited by the TCH diffusion through the boundary liquid layer, well described TCH adsorption. Maximum TCH adsorption occurred at about pH = 6–8. While solution cations including Na+, K+ and Mg2+ subdued TCH adsorption as they competed for ...
The adsorbance, once stable was found to be 753.29mg/kg for corn straw biochar and 1003.70mg/kg for peanut shell biochar.The adsorption characteristics of ammonium nitrogen by corn straw biochar and peanut shell biochar are more fitted to the Freundlich equation (Freundlich adsorption isotherm), ...
