“…This is because as the temperature of the adsorption system elevated, the mobility of the ions in solution increased, leading to increased interactions between BSSPs and CQP molecules. 56 The ANOVA test and the posthoc test using the Duncan multiple range test (DMRT) were The obtained Pvalue (0.072) was found to be greater than 0.05 (Table S6), which implied that there exists a significant difference among the investigated temperatures. Also, the DMRT analysis (Tables S7 and S8) showed that there is a slight difference between the percentages adsorbed at 26 and 35 °C, a slight difference between 35 and 45 °C, and a significant difference between 26 and 55 °C.…”

The present study investigated the potency of biochar prepared from Blighia sapida seedpods (BSSPs) in the uptake of chloroquine phosphate (CQP) from single-component batch and multicomponent fixed-bed adsorption systems. BSSPs presented a highly porous structure with a BET surface area of 1122.05 m 2 /g, to which adsorption efficiency correlated. The Dubinin−Radushkevich isotherm energy was obtained as 129.09 kJ/mol, confirming the chemisorption nature of the BSSP-CQP adsorption system. The efficiency of the artificial neural network (ANN) was evaluated using the lowest mean square error (MSE = 7.27) and highest correlation coefficient (R 2 = 0.9910). A good agreement between the experimental results and the ANNpredicted data indicated the efficiency of the model. The percentage removal of 95.78% obtained for the column adsorption studies indicated the effectiveness of BSSPs in a multicomponent system. The mechanism of the interaction proceeded via hydrogen bonding and electrostatic attraction. This was confirmed by the high desorption efficiency (69.11%) with a HCl eluent. The degree of reversibility was found to be 2.95, indicating the reusability potential of BSSPs. BSSPs are therefore considered multilayered adsorbents with potential applications in pharmaceutical wastewater treatment.

Clays considered “problematic” swelling clay soils in the construction of road infrastructures. They generally associated with high compression, high plasticity, and evolutionary behavior. The objective of this article is to study the mechanical behavior of swelling clays and particularly a clay from the Kenitra region. To do this, samples taken from the main clay sites in the region. They then subjected to several series of tests in the laboratory, namely identification tests and mechanical tests (shear test and odometer compressibility test). The results obtained show that the clays studied exhibit very different behaviors. Indeed, the clays of Sidi Slimane, Sidi Kacem and Ouazzane have very interesting mechanical characteristics and can offered in their natural state as road materials, at least for pavements. Ouazzane clay, on the other hand, has very swelling mechanical characteristics (Cg = 0.06), and clay from Sidi Slimane (Cg = 0.04) and Sidi Kacem (Cg = 0.05) and cannot be used in its raw state. Natural without any treatment.

“…The pseudo-second-order Ho model showed that the adsorption of MB on Fe3O4-TD involved two surface sites, and the solid capacity of Fe3O4-TD affected the adsorption process more than the concentration of MB solution. The interaction mechanism between MB and Fe3O4-TD occurred through chemosorption [24,25].…”

Methylene blue is a popular dye used in the batik industry; however, it potentially causes environmental problems in view of the residual MB content in the liquid waste, which is difficult to naturally degrade. This study aimed to synthesize Fe3O4-TD using tea dregs from household waste and its application as an adsorbent for methylene blue dye. The synthesis was carried out using the reverse co-precipitation method with water as a solvent at room temperature. Fe3O4-TD characterization using FTIR, XRD, and PSA. The adsorption of methylene blue (MB) on Fe3O4-TD was studied at various pH MB, reaction time, and concentration MB to determine the kinetic model and MB adsorption isotherm on Fe3O4-TD and the interactions that occur between MB and Fe3O4-TD. FTIR spectra and X-Ray diffractogram showed that the magnetite formed in a pure state did not mix with other iron oxides. The crystal and particle size of Fe3O4-TD is 18.92 nm and 26.70 µm, respectively. MB adsorption on Fe3O4-TD occurred well at pH > 3 and followed the Ho' pseudo-second-order kinetics model and the Freundlich isotherm model. The interactions between MB and Fe3O4-TD through electrostatic interactions, hydrogen bonds, and phi-phi interactions.
