“…However, the presence of these peaks after calcination is likely due to water absorption from the atmosphere because the calcination at 800 C is high enough that remove all the structural water from the samples. In the as-prepared powders, the peak at around 1359 cm -1 is due to the nitrate groups [65] which probably is pertinent to residual metal nitrate precursors. This absorption peak disappeared after the calcination of powders which shows the decomposition of nitrate groups.…”

In the present work, CuO/CuFe2O4 nanoparticles were synthesized via a polyacrylamide gel. The produced nanocomposites were utilized as a gas sensor for the detection of H2S gas. The nanoparticles were characterized via XRD, FTIR, SEM and TEM techniques. XRD results revealed that the as-prepared product was amorphous and CuO and CuFe2O4 phases were formed after calcination at 800°C. Microstructural studies showed that the nanoparticles have a particle size distribution ranging from 60 to 120 nm. Most of the particles had a spherical morphology. The polyacrylamide network acted as a template for the formation of the nanoparticles. The H2S gas sensing characteristics of the products were studied at different concentrations and operating temperatures. In addition, the effect of humidity on the gas-sensing response was investigated. The prepared CuO/CuFe2O4 sensors can respond up to 25 when exposed to 10 ppm H2S which is higher than the pure CuO or CuFe2O4 sensors. The sensors reached a detection limit of 0.1 ppm and demonstrated clear sensitivity and quick response and recovery behavior toward H2S gas. The CuO/CuFe2O4 heterogeneous nanostructures also showed proper H2S gas response and selectivity in response to interfering gases like NH3, NO2, HCHO and CO. The gas sensing mechanism of the composites was also discussed.

“…Figure 12 shows the FTIR spectra of OBDC. The obvious vibration band appeared at 3000-2800 cm −1 , which was corresponding to the stretching vibration of the saturated CH bond (Danial et al 2019); A peak appeared 910~650 cm −1 was ascribed to CH bending vibration in benzene ring (Medviediev and Daszkiewicz 2020); The peak in the range of 1460-1380 cm −1 was attributed the CH bond deformation vibration peaks of the CH 3 /CH 2 group (Gautam et al 2020). The infrared spectrum of the treated OBDC had no obvious difference compared with that of untreated OBDC.…”

In this study, demulsification separation-Fenton oxidation technology was employed as a combined technology to treat total petroleum hydrocarbons (TPH) in oil-based drill cuttings (OBDC). Batch experiments were carried out to optimize the technology parameter. Under the optimal condition, 70% and 51% TPH removal rate was obtained for demulsification technology and Fenton oxidation technology, respectively. Eighty-five percent of TPH removal rate was obtained using combination technology of demulsification separation and Fenton oxidation. Multiple characterizations were used to analyze the physical and chemical properties of treated OBDC. The result of XRD pattern indicated the combination technology had no obvious effect for structure phase of OBDC. The results of FTIR, GC-MS, TG-DTG and SEM were used to characterize the treated OBDC. This paper provides an efficient and feasible combined technology for OBDC treatment, which expands a new strategy for the removal of TPH from solid waste

“…Alkali (Na + ve K + ) ve geçiş metal (Ag + ) komplekslerinin (NaL, KL2, AgL) IR spektrumlarında liganddan farklı olarak her bir kompleks için sırasıyla 1333, 1331 ve 1331 cm -1 de şiddetli pikler kaydedilmiştir. Bu piklerin, NaL ve KL2 komplekslerinde yapıdaki nötralleştirici pikrat anyonundaki ve AgL kompleksinde yine nötralleştirici anyon olarak bulunan nitrat grubundaki N-O bağına ait gerilme titreşimleri olduğu düşünülmüştür [20][21][22]. Ligand (L) için 972 cm -1 , 874 cm -1 ve 939 cm -1 'deki pikler taç eter halkasına ait iskeletsel konformasyon pikleri olarak belirlenmiştir [23].…”

Bu çalışmada 4′,5′-bis(bromometil)benzo-15-crown-5 ile 2-iyodo-3-hidroksipiridin etkileştirilerek, yeni, çift kollu taç eter ligandı (L) sentezlenmiştir. Sentezlenen ligand (L), Na+ ve K+ kompleksi elde etmek üzere sodyum pikrat ve potasyum pikrat ile tepkimeye sokulmuştur. Böylelikle, benzo-15-crown-5’in halka boşluğuna uygun olan Na+ ile 1:1 (filling) kompleksi (NaL) ve halka boşluğundan daha büyük olan K+ ile 1:2 (sandviç) kompleksi (KL2) elde edilmiştir. Ayrıca bileşik L’nin gümüş nitrat ile reaksiyonu sonucunda geçiş metal kompleksi (AgL) sentezlenmiştir. Elde edilen ligand ve komplekslerin yapısı, spektroskopik yöntemler (FTIR, HRMS, 1H-NMR, 13C-NMR) kullanılarak aydınlatılmıştır. Son olarak, sentezlenen ligand ve komplekslerin termal özellikleri TGA - DTA yöntemleri kullanılarak incelenmiş ve bileşik yapıları ile uyumlu sonuçlar elde edilmiştir.
