Abstract Tetracycline (TC) is a prominent antibiotic that remains largely unmetabolized in humans and animals, resulting significant excretion into the environment. This poses substantial threat to human health, highlighting urgent necessity for effective removal of TC from water sources. A series catalytic materials were prepared by subjecting natural psilomelane (NP) roasting at varying temperatures subsequently employed activate persulfate degradation tetracycline. The roasted 500 °C...
Given the potential risks of chlorinated polycyclic aromatic hydrocarbons, analysis their presence in water is very urgent. We have developed a novel procedure for determining hydrocarbons based on solid-phase extraction coupled with gas chromatography and mass spectrometry. The parameters were optimized detail. Under optimal conditions, proposed method showed wide linear ranges (1.0-1000 ng/L) correlation coefficients ranging from 0.9952 to 0.9998. limits detection quantification range...
Bimetallic Fe/Ni nanoparticles were synthesized and their nitrate reduction capacity was studied. Nitrate (354 mg L−1, equal to 5.71 mmol L−1) performed using with various Ni contents (1.0, 5.0, 10 20%) in an unbuffered condition. Optimum rate () obtained 5.0% nano-scale Fe/Ni, while only 25% transformed by Fe0 within the same reaction time, which means that these bimetallic are obviously more reactive than mono-metallic Fe0. For this system a near-neutral initial pH (6.5) is favourable...
A rapid, simple and efficient method was first applied to the simultaneous analysis of BPA TBBPA in commercial milk.
The CeO 2 , ‐ZrO and ‐WO 3 catalysts were prepared by hydrothermal method used to the selective catalytic reduction of NO x NH . addition ZrO or WO into was favorable for pore structure, then improved number active sites. Besides, introduction could improve Lewis acid sites while contribute generation Brønsted sites, which performance N selectivity. catalyst exhibited optimal activity with above 90% conversion at 220–425 °C approximately 100% selectivity 150–425 °C.
Three kinds of three‐dimensional (3D) Mn 2 O 3 catalysts with different morphologies (cube, fan‐like structure, and sphere) various exposed crystal planes were prepared by a hydrothermal method for benzene oxidation. The activity results suggested that sample ‐Cl hierarchical cube morphology exhibited better rate degradation than the other samples. lowest complete conversion temperature ( T 90 = 252°C), which was ~48°C lower ‐S sample. Meanwhile, R m s values 2.71 3.21 times, respectively,...
In this research, the heterogeneous photoelectron-Fenton-like process using copper ferrite (CuFe2O4) as catalyst was employed to remove p-nitrophenol (PNP). The CuFe2O4 prepared by a co-precipitation and characterised with X-ray fluorescence analysis, diffraction analysis BET surface area. results confirmed that successfully. Under optimum conditions, namely 0.05 mol L−1 Na2SO4, electrical potential of −0.6 V, pH 3.0 0.067 g CuFe2O4, 92.8% 0.1 mM L−1, PNP removal efficiency could reach for...
An ionic liquid-coated etched stainless steel fiber was prepared for solid-phase microextraction of organophosphorus flame retardants from water.
The formation schematic is representative of the CN/O-doped ZIS composite. First, pure g-C 3 N 4 powder was prepared by directly calcining melamine in a muffle furnace. Then composites were via hydrothermal method.
Titanium silicon molecular sieve (TS-1) is an oxidation catalyst that possesses a long lifetime of charge transfer excited state, high Ti utilization efficiency, large specific surface area, and good adsorption property; therefore, TS-1 acts as Ti-based photocatalyst candidate. In this work, coupled Bi
