BR13 dye removal using sodium dodecyl sulfate modified montmorillonite: Equilibrium, thermodynamic, kinetic and reusability studies

Reaktif turuncu 16 boyasının, katalizör olarak manyetik nano boyutlu kil kullanılarak heterojen Fenton prosesi ile parçalanması: Bir Merkezi kompozit optimizasyon çalışması

“…Based on the reports of Lee and Tiwari (2012) [30] and Chang et al (2016) [29], they attributed a similar situation to the replacement of Ca and Mg ions in the structure of MMT with hydrogen ions added to the silicate layers and the loss of water in these intermediate layers during synthesis. According to this result, it can be concluded that there is a tightening in the interlayer space of MMT, and The 3694 cm -1 and 3622 cm -1 peaks observed in the FTIR spectrum correspond to the stretching vibration of the -OH groups in the structure of MMT [31,32]. It can also be said that these bands, which are The surface morphology and elemental compositions of Fe 3 O 4 / MMT samples were determined with SEM/ EDX analysis, and the results are shown in Figure 3.…”

“…Montmorillonite (MMT) is mostly a clay group with a smectite structure. Smectite structures have two inward silica layers [19,20] and a gibbsite layer compressed into these layers [21], and an Al octahedral layer is present in the centre of this layer. MMTs, which can be found in many parts of the world, are found quite widely in Turkey.…”

An investigation based on removal of ibuprofen and its transformation products by a batch activated sludge process: A kinetic study

“…k id refers to the intra-particle diffusion rate constant (mg/g.min 1/2 ). The slope of the line obtained from the graph of q t against t 1/2 gives k id , and the intersection gives C. C gives the experimenter an idea of the boundary layer thickness [50].…”

Hierarchical layered double hydroxide for the removal of charged dyes: the role of an anionic surfactant

“…Interestingly, the introduced SDS can not only change the positive surface charge of LDH to negative but also adjust the surface properties to hydrophobicity (Bayram et al, 2020). Numerous reports unveil that such evolution is favorable for cationic pollutants removal on adsorbents (Lin et al, 2018;Liu et al, 2021;Romero Ortiz et al, 2021).…”

“…In our previous work, we had successfully prepared an organic hierarchical LDH (HLDH) via a soft-template method using sodium dodecyl sulfate (SDS) as a template agent and intercalated anions (Zhang et al, 2019a). Interestingly, the SDS introduced not only changed the positive surface charge of the LDH to negative, but also rendered the surface hydrophobic (Bayram et al, 2020). Numerous reports reveal that such an evolution is favourable for cationic pollutant removal with adsorbents (Lin et al, 2018;Liu et al, 2021;Romero Ortiz et al, 2021).…”
