Synergistically active FeO magnetic and EDTA modified cellulose cotton fabric using chemical method and their effective pollutants removal ability from wastewater.

A unique combination of cotton fabric (CF) with a mixture of EDTA and APTES FeO magnetic particles was developed and utilized for the first time as an adsorbent for removing pollutants from wastewater. Initially, FeO was synthesized using the co-precipitation method. Further, the surface of FeO was modified by introducing amino functional groups through a reaction with APTES, resulting in FeO-NH.

Synthesis of cellulose cotton-based UiO-66 MOFs for the removal of rhodamine B and Pb(II) metal ions from contaminated wastewater.

The presence of pollutants in drinking water has become a significant concern recently. Various substances, including activated carbon, membranes, biochar, etc., are used to remove these pollutants.

High-performance Cu/Mn modified ceramsite as a persulfate activator to degrade oxytetracycline in batch Erlenmeyer flask and continuous-flow fixed-bed column systems: An exploration of its practicability and non-radical mechanisms.

Persulfate non-radical oxidation have excellent catalytic capability for degrading specific contaminants in complicated water environments. Nevertheless, the preparation of high-performance activators and their application in actual water treatment in continuous flow mode are still scarce and unsatisfactory. In this work, copper-, manganese-, and copper/manganese-doped ceramsites (Cu-C, Mn-C and Cu/Mn-C), successfully fabricated through a facile impregnation-calcination approach, were characterized and evaluated for their performance to activate potassium peroxydisulfate (PDS) and degrade oxytetracycline (OTC) under different pH, ceramsite dosages, and PDS dosages.

The Synergistic Inhibitions of Tungstate and Molybdate Anions on Pitting Corrosion Initiation for Q235 Carbon Steel in Chloride Solution.

In this work, the synergistic inhibitions of tungstate (WO) and molybdate (MoO) anions, including role and mechanism, on the initiation of pitting corrosion (PC) for Q235 carbon steel in chloride (Cl) solution were investigated with electrochemical and surface techniques. The pitting potential (E) of the Q235 carbon steel in WO + MoO + Cl solution was more positive than that in WO + Cl or MoO + Cl solution; at each E, both peak potential and affected region of active pitting sites in WO + MoO + Cl solution were smaller than those in WO + Cl or MoO + Cl solution. WO and MoO showed a synergistic role to inhibit the PC initiation of the Q235 carbon steel in Cl solution, whose mechanism was mainly attributed to the influences of two anions on passive film.

Comparative Toxicity, Biodistribution and Excretion of Ultra-Small Gold Nanoclusters with Different Emission Wavelengths.

The exponentially increased use of gold nanoclusters in diagnosis and treatment has raised serious concern about their potential threat to living organisms. However, the mechanisms of toxicity of gold nanoclusters and remain poorly understood. In this work, comparative toxicity studies, including biodistribution and excretion, were carried out with mildly and chemically synthesized ultra-small L-histidine-protected and bovine serum albumin (BSA)-protected gold nanoclusters in an all-aqueous process.

Uniform hollow spherical rhombohedral LaMO3 and solid spherical cubic MOx (M = Mn and Co) NPs were fabricated using the PMMA-templating strategy. Hollow spherical LaMO3 and solid spherical MOx NPs possessed surface areas of 21-33 and 21-24 m(2)/g, respectively. There were larger amounts of surface-adsorbed oxygen species and better low-temperature reducibility on/of the hollow spherical LaMO3 samples than on/of the solid spherical MOx samples.
