“…Meanwhile, the equilibrium solution pH increased from about 3.7 at 0.25 h to 4.0 at 8 h. However, this minute increase in solution pH should have minimal influence on MT uptake as indicated from the pH study (see later). A similar trend was found for amitriptyline adsorption on kaolinite [27] and was attributed to an increase in pzc of kaolinite with time [43]. In comparison to kaolinite, Equilibrium MT concentration (mmol/L) Amount MT sorbed (mmol/kg) significant higher MT uptake was found on talc (7.6-8.3 mmol/kg vs. 3.7-4.0 mmol/kg), in an agreement with the results from the isotherm study.…”

“…Thus, the intensive interaction between kaolinite and humic acid (HA) is primarily controlled by the surface acid-base properties. Kaolinite clay has seldom been used as adsorbents because of its low cation exchange capacity (CEC, 3-15meq/100g) and small surface area, which is not more than 20m 2 g −1 [4,5]. Modification of clay minerals can be achieved by either impregnation or grafting of organic/inorganic molecules on its surface [6].…”

Kaolinite clay has low cation exchange capacity and small surface area; it has rarely been used as adsorbent. As well as, green, low cost and efficient adsorbent is desired. Modification of kaolinite is necessary to improve its adsorption capacity. Jordanian kaolinite has been modified by humic acid (HA) through batch adsorption mode. Two types of HA were used; one was commercial (FHA) and the other was natural (KTD). The effect of HA concentration, pH and temperature of solution were considered. HA adsorption becomes higher at low concentration, decreases with increasing pH, and it increased with solution temperature. Modified Jordanian kaolinite clay was characterized by different techniques: FTIR, TGA, SEM connected to EDS and porosimetry analysis by Gas Adsorption Isotherm and Mercury Porosimetry. The modified kaolinite showed good and strong interaction with HA, enhancement in its surface and charge structure, and increasing in the average pore radius. Therefore, increases in its reactivity and adsorption sites especially towards heavy metal ions. Moreover, FHAkaolinite clay showed better adsorption characteristics than KTD-kaolinite clay.

“…Although AMI is comparatively more toxic (especially at low doses) than the selective serotonin reuptake inhibitors (SSRI), it is still widely prescribed due to its low price [ 1 ]. The extensive use of AMI has resulted in its frequent detection in wastewater, surface runoff and effluent from sewage treatment plants, and as such, these waters could potentially reach agricultural land through the application of municipal biosolids or reclaimed water use [ 4 ]. Therefore, many techniques for the removal of this contaminant from aqueous media have been studied, such as: advanced oxidation processes (UV radiation and Fenton reagent) [ 5 ], membrane bioreactors [ 6 ], distillation membranes [ 7 ], and adsorption [ 2 , 3 , 4 ], among other techniques.…”

Cellulose derivatives have been widely used as adsorbents for the removal of micropollutants such as drugs, dyes, and metals, due to their abundance, low cost and non-contaminating nature. In this context, several studies have been performed searching for new adsorbents (cellulose derivatives) efficient at contaminant removal from aqueous solutions. Thus, a new adsorbent was synthesized by chemical modification of cellulose with ethylenediamine in the absence of solvent and applied to the adsorption of amitriptyline (AMI) in aqueous solution. The modification reaction was confirmed by X-ray Diffraction (XRD), elemental analysis, Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetry/Differential Scanning Calorimeter (TG/DSC), solid state Nuclear Magnetic Resonance of 1H and 13C (1H-NMR and 13C-NMR). Moreover, the effectiveness of reaction was confirmed by computational calculations using Density Functional Theory (DFT) at level B3LYP/6-31G(d). This adsorption process was influenced by pH, time, concentration, temperature and did not show significant changes due to the ionic strength variation. Through these experiments, it was observed that the maximum adsorption capacity of AMI by CN polymer at 298 K, 300 min, and pH 7 was 87.66 ± 0.60 mg·g−1.
