Titanium dioxide manganese/multi-walled carbon nanotubes (MTiO₂/x-CNT) nanocomposites were successfully prepared using the sol-gel method by reaction specific amounts of CNT with titanium dioxide and manganese, aiming to shift the band edge toward longer wavelengths and provide more effective separation of electron-hole pairs. The MTiO₂ and MTiO₂/C...

In this work, biochar synthesized from orange peel modified with magnetite was used as an alternative magnetic adsorbent for dye removal. The magnetization of the synthesized biochar was done using the co-precipitation method. The obtained composite was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Raman spectros...

Pharmaceutically active compounds (PhACs), Diclofenac (DFC), Ibuprofen (IBU), and Paracetamol (PRC) are anti-inflammatory drugs commonly detected in wastewater. These micropollutants (pharmaceuticals) are not completely removed in conventional wastewater treatment plants. Therefore, alternative treatment methods are needed. In this context, the rem...

The continuous produce of sewage sludge generated by the treatment of wastewater in wastewater treatment plants poses a serious environmental problem. The characterization of sewage sludge before its reuse in safe way becomes very important. The aim of this study is the characterization of sludge and calcined sludge in different temperatures in the...

The principal objective of this study was to investigate the adsorption capacity of a modified local natural bentonite (NBT) with magnetite (NBT/Fe 3 O 4) for some heavy metals. The NBT/Fe 3 O 4 particles were prepared via co-precipitation method and characterized with X-ray diffraction (XRD), X-ray fluorescence (XRF) Scanning Electron Microscopy (...

The title compound, [Cu(C5H3N6)2(H2O)2]·2C5H3N3, is a 1:2 co-crystal between the mononuclear complex di­aqua­bis­[5-(pyrazin-2-yl)tetra­zolato]copper(II) and the reagent pyrazine-2-carbo­nitrile which was used in the synthesis. The CuII atom is located on an inversion centre and has a distorted octa­hedral [4 + 2]-coordination environment formed by...

The title zwitterion, C17H14N2O2, crystallizes with two independent mol­ecules in the asymmetric unit, both of which are approximately planar, the dihedral angles between the benzene ring and the naphthalene ring system being 4.39 (12)° in one mol­ecule and 5.83 (12)° in the other, and show an E conformation with respect to the azo double bond. An...

In the title zwitterionic compound, C16H12N2O, the dihedral angle between the phenyl ring and the naphthalene ring system is 17.85 (8)°; an intra­molecular N—H⋯O hydrogen bond occurs. In the crystal, π–π stacking is observed between naphthalene ring systems of adjacent mol­ecules, the centroid–centroid distance being 3.6486 (11) Å.

The title azo mol­ecule, C16H9Br3N2O, adopts a trans conformation with respect to the azo N=N double bond. An intra­molecular O—H⋯N hydrogen bond forms an S(6) ring motif. The dihedral angle between the naphthalene ring system and the benzene ring is 33.80 (16)°. In the crystal, mol­ecules are stacked in columns along the a axis by π–π inter­action...
