Background: Based on the low volatility and refractory nature of Tetracycline (TC), excessive use leads to its continuous accumulation in water environments, posing serious risks to the ecological environment and human health. Although a very limited number of nanomaterials capable of simultaneously detecting and removing TC have been fabricated, they generally exist issues associated with a single detection signal ("on" or "off") or low adsorption rates with low adsorption capacities. As a result, it is crucial to develop a reliable technique to achieve ratiometric detection as well as rapid and efficient removal of TC.

The visible-light-driven O evolution on oxychloride photocatalysts, such as BiNbOCl, was significantly enhanced by stirring in an aqueous solution containing IrCl in the dark. Various characterizations indicated that highly dispersed IrOHCl-like species spontaneously formed on the oxychloride surface, serving as effective and stable cocatalysts for enhancing O evolution.

Humic acid (HA) enhances colloidal transport in porous media, yet the mechanisms by which the HA adsorption conformation affects colloid transport remain unclear. This study investigated the influence of HA on the transport of petroleum-hydrocarbon-contaminated soil colloids (TPHs-SC) in saturated sand columns. The presence of TPHs on the colloidal surface occupied adsorption sites, hindering HA from forming a horizontal adsorption conformation, as observed on uncontaminated soil colloids (SC).

With high microporosity, good dispersibility, excellent specific surface area and large content surface functional group, hydrochar demonstrates significant advantages and strong affinity towards pollutants in water. Modification method plays a significant role for anion adsorption by modified hydrochar, layered double hydroxide (LDH) modified hydrocarbons (Mg/Al-LDH@HC-HCl) have been synthesized through a one-step hydrothermal approach and activated with hydrochloric acid in this paper. The physical and chemical characteristics of the hydrochar, both before and after modification, are analyzed using BET, SEM-EDS, TEM, XRD, FTIR, and XPS to explore the phosphate adsorption mechanisms.

Polycyclic Aromatic Hydrocarbons (PAHs) and Polychlorinated Biphenyls (PCBs) are recalcitrant organic pollutants often detected in stormwater. Various stormwater control measures (SCMs) can remove PAHs and PCBs by filtration, adsorption, and biodegradation. However, dissolved PAHs and PCBs remain present in the treated outflow of SCMs.
