Evaluating the Effectiveness of Coagulation–Flocculation Treatment Using Aluminum Sulfate on a Polluted Surface Water Source: A Year-Long Study

Water, Journal Year: 2024, Volume and Issue: 16(3), P. 400 - 400

Published: Jan. 25, 2024

Safeguarding drinking water is a major public health and environmental concern because it essential to human life but may contain pollutants that can cause illness or harm the environment. Therefore, continuous research necessary improve treatment methods guarantee its quality. As part of this study, effectiveness coagulation–flocculation using aluminum sulfate (Al2(SO4)3) was evaluated on very polluted site. Samplings were taken almost every day for month from site, samples characterized by several physicochemical properties, such as hydrogen potential (pH), electrical conductivity, turbidity, organic matter, ammonium (NH+4), phosphate (PO43−), nitrate (NO3−), nitrite (NO2−), calcium (Ca2+), magnesium (Mg2+), total hardness (TH), chloride (Cl−), bicarbonate (HCO3−), (SO42−), iron (Fe3+), manganese (Mn2+), (Al3+), potassium (K+), sodium (Na+), complete alkalimetric titration (TAC), dry residue (DR). Then, these treated with Al2(SO4)3 jar test method, which common method determine optimal amount coagulant add based characteristics. A mathematical model had been previously created support vector machine predict dose according parameters temperature, pH, TAC, turbidity. This step repeated at end each year, second characterization carried out in order compare them those raw water. The results showed effective elimination various pollutions, high rate, thus demonstrating Al2(SO4)3. measured after significant reduction majority parameters. These demonstrated eliminating pollutions present They also stress importance continued field quality protect

Diversity of Iron Oxides: Mechanisms of Formation, Physical Properties and Applications

Magnetochemistry, Journal Year: 2023, Volume and Issue: 9(5), P. 119 - 119

Published: April 27, 2023

Iron oxide compounds have naturally formed during the whole of Earth’s history. Synthetic compositions with iron oxides are produced use various techniques and widely used for scientific applied purposes. This review considers an attempt to classify all information on different compound formation mechanisms intended applications in biomedicine, catalysis, waste remediation, geochemistry, etc. All literature references analyzed were divided into several groups by their number included compounds: containing only one (e.g., magnetite or wüstite), including polymorphs iron(III) (α-, β-, γ-, ε-, ζ-, δ-Fe2O3); two distinguishable phases maghemite hematite); non-crystalline (amorphous atomic clusters); mixed (indistinguishable separate phases). Diagrams distribution between built. Finally, outlook perspectives further studies is provided.

Chemical Engineering Journal, Journal Year: 2024, Volume and Issue: 490, P. 151725 - 151725

Published: April 27, 2024

Addressing the ecological risks and human health threats posed by emerging contaminants requires development of reproducible scalable materials technologies. In this context, performance multicore flower-shaped nanoparticles (NFs) with approximately 40 nm diameters was assessed for extracting degrading polyethylene microplastics found in cosmetics from water samples. These NFs, exhibiting cooperative magnetic behavior high moment per particle, were synthesized a larger reactor (1 L), yielding quantities 91 % mean reproducibility. The NFs directly attached to microplastic surfaces via ultrasonic treatment separated using permanent magnet, demonstrating removal capacities up 1000 mgMP/gNF under optimal conditions (pH 7, 10 mg 30 min, field strength 320 kA/m). Subsequently, aqueous suspensions hydrolyzed at 150 °C followed mineralization through Fenton-like reaction catalyzed where reactive oxygen species produced, presence H2O2, break organic molecules. Mineralization yields ranged 20 75 90 °C, further increase 78 achieved an alternating (60 mT, 100 kHz), obviating need temperatures. results highlight potential associated technologies effectively addressing challenges contaminants, offering promising avenues environmental remediation protection.

Cubic Mesocrystal Magnetic Iron Oxide Nanoparticle Formation by Oriented Aggregation of Cubes in Organic Media: A Rational Design to Enhance the Magnetic Hyperthermia Efficiency

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(27), P. 32162 - 32176

Published: June 30, 2023

Magnetic iron oxide mesocrystals have been reported to exhibit collective magnetic properties and consequently enhanced heating capabilities under alternating fields. However, there is no universal mechanism fully explain the formation pathway that determines particle diameter, crystal size, shape of these their evolution along with reaction. In this work, we analyzed cubic by thermal decomposition in organic media. We observed a nonclassical leads via attachment crystallographically aligned primary particles grows through sintering time achieve sizable single crystal. case, solvent 1-octadecene surfactant agent biphenyl-4-carboxylic acid seem be key parameters form as intermediates reaction presence oleic acid. Interestingly, hyperthermia efficiency aqueous suspensions strongly depend on degree aggregation cores forming final particle. The highest saturation magnetization specific absorption rate values were found for less aggregated mesocrystals. Thus, stand out an excellent alternative biomedical applications properties.
