This study explores a novel method for detecting neonicotinoid insecticides, imidacloprid (IMD) and dinotefuran (DNT), in water using terbium (Tb) ions photo probe. The optimal excitation and emission wavelengths for Tb luminescence were identified at 310 nm and 545 nm, respectively. The influence of pH and solvent on Tb-complex fluorescence was investigated.

Article Synopsis
  • Oily wastewater from the oil industry and spills poses a significant environmental issue, prompting research for effective solutions.
  • A novel magnetic Ni-Al oxide/ZnCoFO mesoporous aerogel (MNA) was developed as a selective adsorbent for oil removal, with oleic acid (OA) enhancing its hydrophobic properties more effectively than Triton X-100 (TX).
  • The MNA-OA exhibited a remarkable oil removal efficiency of about 97% and maintained high stability and reusability across five uses, thanks to the strong chemical bonding of OA.

Innovative technologies are needed to enhance access to clean water and avoid waterborne diseases. We investigated the performance of cold atmospheric plasma (CAP), a clean and sustainable approach for microbial inactivation and total organic carbon (TOC) degradation in environmental water. Water matrices played a crucial role in the performance of CAP efficacy; for example, complete removal of ɸX174 from dHO required 1 min of treatment, while ɸX174 reductions of ~ 2log and 4log were obtained after 10 min of CAP exposure in river water and wastewater samples, respectively.

Article Synopsis
  • Scientists made special materials called magnetic SiO/ZnCoFeO aerogels using a process called sol-gel method and dried them in two ways: air drying and freeze-drying.
  • They altered the surface of these materials to make them water-repelling (hydrophobic) with something called oleic acid.
  • The materials were effective at soaking up oil from water, showing that they could be used to clean up oil spills and help the environment, especially the freeze-dried version which worked even better.

Nanotechnologies have been advantageous in many sectors and gaining much concern due to the unique physical, chemical and biological properties of nanomaterials (NMs). We have surveyed peer-reviewed publications related to "nanotechnology", "NMs", "NMs water treatment", "NMs air treatment", and "NMs environmental risk" in the last 23 years. We found that most of the research work is focused on developing novel applications for NMs and new products with peculiar features.

This study aimed to investigate the synergistic effect of the cold atmospheric plasma (CAP) and heterogeneous photocatalytic processes in an aqueous solution to enhance water purification efficacy and reduce the energy cost required by CAP. 0.1% Ag/TiO-reduced graphene oxide (rGO) nanoparticles (NPs) photo-composite were prepared and fully characterized.

Membrane fouling is a common problem in membrane technology and causes detrimental effects for the applied membranes such as loss of integrity and productivity. Henceforward, we devoted this work to fabricate membranes that pose favored criteria in the direction of alleviating membrane fouling incidence. Herein, the fabricated membranes were traced via an assortment of both experimental and molecular modeling verifications to understand the mechanism of interaction.

Recently, naturally occurring biopolymers have attracted the attention as potential adsorbents for the removal of water contaminants. In this work, we present the development of microcrystalline cellulose (MCC)-based nanogel grafted with acrylamide and acrylic acid in the presence of methylene bisacrylamide and potassium persulphate as a crosslinking agent and initiator, respectively. World-class facilities such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), surface analysis, field emission scanning electron microscopy (FE-SEM), high resolution transmission electron microscopy (HR-TEM) and zeta sizer were used to characterize the synthesized MCC based nanogel.
