This paper presents a sub-pilot scale process of synthesis Na-P1 zeolite from the coal fly ash. After establishing appropriate conditions (20 kg ash, 12 NaOH, 90 dm3 water, reaction temperature: 80 °C and time: 36 h), high-purity (81 wt%) product was obtained. Its chemical, mineralogical, textural properties were determined (by means XRD, XRF, SEM–EDS ASAP 2020). The synthesized material has specific BET surface area (88 m2/g) c.a. six times higher than ash which it been derived (15 m2/g)....
The mesoporous silicate molecular sieve, MCM-41, has been synthesized from pulverized coal fly ash (PFA), where the filtrate used is a by-product hydrothermal zeolite production. Rice husk was also for comparison but fusion with sodium hydroxide to prepare filtrate, along similar lines earlier reports of using PFA as precursor MCM-41 synthesis. samples are chemically and mineralogically commercially available sample, higher pore volumes dominated by mesopores (0.92–1.13 cf. 0.88 cm3 g−1)....
Natural extracts are a rich source of biomolecules that useful not only as antioxidant drugs or diet supplements but also complex reagents for the biogenic synthesis metallic nanoparticles. The natural product components can act strong reducing and capping substrates guaranteeing stability formed NPs. current work demonstrates suitability Camellia sinensis, Ilex paraguariensis, Salvia officinalis, Tilia cordata, Levisticum officinale, Aegopodium podagraria, Urtica dioica, Capsicum baccatum,...
The aim of the research was to compare mechanisms heavy metal ions (Pb(II) and Zn(II)) adsorption on surfaces nanostructured synthetic zeolites: Na-X, Na-P1, their carbon composites: Na-X (C), Na-P1 (C) precursor these structures - high-carbon fly ash (HC FA). carried out in single mixed adsorbate systems. Heavy metals were selected basis toxicity occurrence natural environment. adsorption–desorption electrokinetic data obtained by means inductively coupled plasma-optical emission...
Iron oxide nanoparticles (IONPs) have many practical applications, ranging from environmental protection to biomedicine. IONPs are being investigated due their high potential for antimicrobial activity and lack of toxicity humans. However, the biological is not uniform depends on synthesis conditions, which affect shape, size surface modification. The aim this work synthesise using a mixed method, i.e., chemical co-precipitation combined with biogenic modification, extracts spent hops...
Pure zeolite (Na-X) and a zeolite–carbon composite (Na-X(C)) were investigated as adsorbents of heavy metals—Pb2+ Zn2+ from an aqueous solution. These materials synthesized fly ash—a waste conventional hard coal combustion. Both solids characterized using XRD, SEM-EDS, nitrogen adsorption/desorption, particle size elemental composition analyses. The adsorption study was performed at pH 5 in the systems containing one or two adsorbates simultaneously. obtained results showed that pure by more...
Nowadays, using fly ash for zeolites production has become a well-known strategy aimed on sustainable development. During zeolite synthesis in hydrothermal conversion large amount of post-reaction solution is generated. In this work, the was used as substrate Na-A and Na-X at laboratory technical scale. Obtained materials were characterized particle size analysis, X-ray diffraction (XRD), fluorescence spectroscopy (XRF), transmission electron microscopy (TEM), Fourier transformed infrared...
The use of bacteria in the self-healing process cementitious composites has been recently widely considered. In this study, diatomite and Na-X zeolite were proposed as carrier materials impregnated by Bacillus subtilis endospores. effect impregnation method on a bacterial survival rate (BSR) cement modification strength parameters, was investigated. Additionally, influence healing flexural compressive recovery surface crack repair ratio, assessed. Test results indicated higher BSR for vacuum...
Waste fly ash, with both low (with the addition of vermiculite) and high contents unburned coal, were subjected to hydrothermal syntheses aiming obtain zeolite composite materials-zeolite + vermiculite (NaX-Ver) carbon (NaX-C). The composites compared parent obtained from waste ash a content (NaX-FA). In this study, physicochemical characteristics materials evaluated. potential application investigated zeolites for adsorption ammonium ions aqueous solutions was determined. Composite NaX-Ver...

The reducing...
Abstract The removal of gaseous mercury from flue gases coal-fired power plants is currently an environmental challenge under investigation. Therefore, the main aim this paper was to evaluate suitability faujasite group zeolites (Na-X) adsorb compounds. Previous, initial tests showed negligible Hg 0 uptake by Na-X zeolite, but silver impregnation improved adsorption markedly. testing into Ag + - impregnated synthetic zeolite (Ag-X zeolite) derived coal fly ash carried out.

In recent years, there has been a growing interest in plant pigments as readily available nutraceuticals. Photosynthetic pigments, specifically chlorophylls and carotenoids, renowned for their non-toxic antioxidant properties, are increasingly finding applications beyond health-promoting attributes. Consequently, is an ongoing need cost-effective methods of isolation. This study employs co-precipitation method to synthesize magnetic iron oxide nanoparticles. Scanning electron microscopy...
