Summary: In this study, activated carbon with an ultra-high surface area was fabricated from sawdust by simple, one-step chemical activation. The sawdust activated carbon exhibited a high and rapid removal efficiency toward Rhodamine B, with a removal percentage of nearly 100% after 10 min at an RhB concentration of 10 ppm. The effect of the pH solution on RhB removal performance by sawdust activated carbon showed that the sAC absorbed more than 90% of the RhB in all the pH at room temperature solutions.

Summary: The study aimed to identify the extent of infestations and investigate the factors promoting the spread of purple loosestrife in wetlands. The results showed a significant increase in the number of plants along state highways, with a higher loosestrife density correlating with an increase in plant species richness and a decrease in the distance to the closest infestation and wetland. Mowing was not found to promote the spread, while culverts were identified as enabling the spread of purple loosestrife underneath highways.

Summary: The Zoysia sinica Hance-based activated carbon (ZBAC) showed superior adsorption capacity for Rhodamine B (RhB) removal from aqueous solutions due to its specific surface area and available porosity. The adsorption process followed the Langmuir isotherms model and pseudo-second-order kinetic model, suggesting monolayer and chemical adsorption mechanisms. Ion exchange interactions and hydrogen bonding were found to be dominant in the adsorption of RhB molecules by the activated carbon, providing a promising strategy for developing high-performance adsorbents for dye removal from wastewater.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
