On-site multi-pesticide residues detection is particularly urgent and challenging. Here, we fabricated an enzyme-free ratiometric fluorescent detection system in combination with a hinge-like dual-channel 3D microfluidic paper analytical device (3D μPAD) for simultaneous visual detection of...

While photodynamic inactivation (PDI) has emerged as a novel sterilization strategy for drinking water treatment that recently attracted tremendous attention, its efficiency needs to be further improved. In this study, we aimed to clarify the ultraefficient mechanism by which potassium iodide (KI)...

Maximizing resource recovery by improving the anaerobic treatment efficiency of waste activated sludge (WAS) is critical to reducing carbon emissions. In this study, a concept of "co-treating" WAS with sulfite-laden wastes (sulfite) and mackinawite (FeS) was proposed to improve the anaerobic...

Commercial activated carbon (BAX) and high porosity carbon black (BP) were modified to elucidate the effect of surface chemistry on adsorption of perfluorooctanesulfonic acid (PFOS); the surface of initial BAX was thermally reduced (BAX-HT) and on BP melamine was either deposited or used as source...

In response to the increasingly serious environmental pollution problem, iron-based sulfite activation has been considered as an effective option for environmental remediation. This article aims to make a scientific review of the recent progress on sulfite activation by iron-based materials, as...

A novel three-dimensional electrokinetic remediation (3D EKR) system, with FeO_x/granular activated carbon (GAC) composite constituting a third electrode was investigated for the removal of Cr from a real contaminated soil. Such third electrode particles were distributed evenly throughout the...

Sulfate radicals (SO₄^.-) are typically regarded to be the dominant active species in the cobalt-activated peroxymonosulfate (PMS) processes. In this study, a water-soluble sulfonated cobalt (II) phthalocyanine (CoPcS) was applied as a molecular catalyst to activate PMS and break down organic...

The coexistence of heavy metal-polluted soils and global warming poses serious threats to plants. Many studies indicate that arbuscular mycorrhizal fungi (AMF) can enhance the resistance of plants to adverse environments such as heavy metals and high temperature. However, few studies are carried...

Introduction: Buckwheat (Fagopyrum tataricum), an important food crop, also has medicinal uses. It is widely planted in Southwest China, overlapping with planting areas remarkably polluted by cadmium (Cd). Therefore, it is of great significance to study the response mechanism of buckwheat under Cd...

Due to human activities, high abundances of nano/microplastics (N/MPs) concurrent with metal pollution have become a serious problem in the global marine environment. Because of displaying a high surface-area-to-volume ratio, N/MPs can serve as the carriers of metals and thus increase their...
