The knowledge of the plants that are used may provide insight on their properties for further exploration. This study aimed to identify and collect data about medicinal plants used in traditional medicine by the population of the provincial region of Taza, Morocco. An ethnobotanical survey was carried out among 200 informants, competent villagers, herbalists, and traditional healers from the provincial region of Taza city through direct interviews using a structured questionnaire. The survey reported 55 plant species belonging to 28 families used in the folk medicine. Informants’ results showed that the most frequently used plants were Origanum compactum, Mentha pulegium, Rosmarinus officinalis L., Aloysia citrodora, Calamintha officinalis Moench, and Artemisia herba-alba Asso., with a relative frequency of citation of 76%, 72%, 60%, 42%, 40%, and 30%, respectively. Moreover, in this study, the Lamiaceae family was the most commonly reported plant family, and the leaves were the most frequently used parts of the plants; otherwise, decoction and infusion were the most used modes in the preparation of remedies from medicinal plants in the traditional medicine. The sociodemographic characteristics showed that women use medicinal plants slightly more than men, the illiterate people use the medicinal plant the most, and old people have more information about the medicinal plants than the new generations. The region of Taza of Morocco has an important floristic biodiversity of medicinal plants which are used in traditional medicine practice. This result provides a good database for pharmacological screening in the search for new plants that can contain new bioactive molecules that can be used as a bioactive ingredient of medicament or as a biological alternative in pharmacology.

“…Therefore, each water pollution treatment method has its speci c applied conditions. In contrast, the adsorption method has the excellent features of fast, high effectiveness, simplicity of operation, less energy cost, and free secondary contamination, which makes the method particularly favorable and attracted more and more attention [13][14][15].…”

The organic dye molecules and pathogenic microorganisms exist widely in printing and dyeing wastewater which will bring severe harm to human beings and the water environment if they are not properly treated. A novel SA/CS/GO gel beads with both adsorption and antibacterial functions are synthesized in the special ways. NaHCO3 is selected as porogen to control the density of gel beads formed by the cross-linking of Ca2+. Ag+ is fixed on outside the beads to optimize the inactivation rate of typical strains. The morphology and composite of the beads are characterized through SEM and FT-IR spectrometer. The adsorption properties of the beads accord with the Langmuir isotherm and quasi-secondary model, that means, the adsorption is monolayer behavior and the reaction rate is controlled through the chemical reaction process. The theoretical adsorption liminal value of MB on the beads can reach 847.46 mg/g. In the range of pH value at 3–11, it also has good adsorption ability. After five rounds of adsorption-desorption experiments, the gel beads still remain favorable performance. At the same time, the sterilization rate of the beads is almost 100% for the selected typical strains, even after several adsorption-desorption cycles, it still has a good bactericidal function. So, this kind of new gel beads is easy to recycle, reusable, and has broad application foreground in the field of water purification, sterilization, and adsorption.

“…The intraparticle diffusion resistance was evaluated using the intraparticle particle diffusion model by Weber and Morris 31 , given by the following equation: where q t (mg/g) is the adsorption amount at time t (min), k id (mg/g/min 1/2 ) is the adsorption rate constant of the intraparticle diffusion model, and c is a constant related to the thickness of the boundary layer. The plot of qt versus t 1/2 is the sole rate-limiting step of the adsorption process if it is linear and passes through the origin 32 . When the lines of uptake pass through the origin, the rate-controlling step is intraparticle diffusion.…”

Textile effluents contain dyes that negatively affect water bodies and inhibit photosynthesis by reducing sunlight penetration. This study investigated the adsorption capacity of an iron oxide sorbent immobilised on naturally derived carbon foam for the removal of organic methylene blue dye from water. In this study, the carbon precursor and iron oxide precursor were mixed and carbonised in a single vessel. Baking and carbonization of the natural grain combination produce a porous structure that can act as an effective support for the iron oxide particles. The carbon foam prepared had a self-assembled structure with flour as a basic element. Sorbents of 6 weight (wt)%, 15 wt% iron, and a 0 wt% iron control sample were prepared. Transmission electron microscopy (TEM) and Brunauer–Emmett–Teller (BET) techniques were used to examine the synthesised carbon foam physical properties and surface morphology. The adsorption capabilities were investigated in batch tests by determining the effects of an increase in iron content, sorbent dosage, contact time, and dye concentration. Breakthrough curves were obtained by varying the height of the sorbent bed and varying the flowrate of the dye solution. A higher bed height corresponds to a greater amount of adsorbent. The breakthrough and equilibrium adsorption capacities were found to increase with increasing bed height. When the flow rate is high, the dye solution leaves the column before equilibrium, resulting in shorter breakthrough and saturation times. Higher bed heights and lower flow rates resulted in optimal dye removal in the flow through the system. Breakthrough time increases with increasing iron content. The 15 wt% iron sample displayed superior adsorption capabilities than the 6 wt% sample, while the 0 wt% iron control sample displayed minimal adsorptive capabilities. The pseudo-first order kinetic model was the best fit model for this study (R2 > 0.96), and the adsorption equilibrium is best described by the Freundlich isotherm (R2 > 0.99). The results showed that an iron oxide sorbent immobilised on carbon foam made from natural sources is a good adsorbent for removing methylene dye.
