“…In addition, the different functional groups present on its surface can facilitate the interactions with molecules of different chemical nature. In the specific case of aromatic compounds such as methylparaben, the surface chemistry plays a relevant role and is directly correlated with the adsorption capacity [18]. For methylparaben, it can be hypothesized that the adsorbate–adsorbent interactions are similar to those presented by phenol, since this latter group is part of the methylparaben molecular structure.…”

“…Therefore, it is expected that the adsorption capacity decreases in the presence of a high concentration of oxygenated groups (acids) on the activated carbon and increases with the basicity of the adsorbent. Simultaneously, the adsorbed amount of methylparaben should decrease along with a pH decrease and an increase in ionic strength [1,13,18,19,20,21]. However, dealing with adsorption, the analysis of the particular adsorbent–adsorbate couple is crucial as each adsorbate has its molecular properties and unpredictable results can arise.…”

In this study, the mechanisms of methylparaben adsorption onto activated carbon (AC) are elucidated starting from equilibrium and thermodynamic data. Adsorption tests are carried out on three ACs with different surface chemistry, in different pH and ionic strength aqueous solutions. Experimental results show that the methylparaben adsorption capacity is slightly affected by pH changes, while it is significantly reduced in the presence of high ionic strength. In particular, methylparaben adsorption is directly dependent on the micropore volume of the ACs and the π- stacking interactions, the latter representing the main interaction mechanism of methylparaben adsorption from liquid phase. The equilibrium adsorption data are complemented with novel calorimetric data that allow calculation of the enthalpy change associated with the interactions between solvent-adsorbent, adsorbent-adsorbate and the contribution of the ester functional group (in the methylparaben structure) to the adsorbate–adsorbent interactions, in different pH and ionic strength conditions. It was determined that the interaction enthalpy of methylparaben-AC in water increases (absolute value) slightly with the basicity of the activated carbons, due to the formation of interactions with π- electrons and basic functional groups of ACs. The contribution of the ester group to the adsorbate-adsorbent interactions occurs only in the presence of phenol groups on AC by the formation of Brønsted–Lowry acid–base interactions.

Pharmaceutical and Public Care Products (PPCP) enable a healthy lifestyle for individuals, but the non-metabolized components get released to the environment, which creates an adverse impact on the environment, especially the aquatic ecosystem. PPCP is considered a secondary pollutant, but it has the potential to become a primary pollutant due to its bioaccumulation and lasting detrimental effects. Primary wastewater treatments like coagulation, sedimentation, and flocculation are not suitable for the exclusion of these contaminants due to their low density and ability to form an emulsion with other constituents. Adsorption is a promising technique due to ease of application, lowcost, and comparatively good efficiency. Adsorbents made from the biological waste make process economical, and proper selection of adsorbent material for the removal of PPCP components reduces the discharge of solid waste to the environment. This review briefly analysis and explain the adsorbents used for seven commonly used second-generation antibiotics, which are used for tract infection.

Green analytical chemistry principles aim to minimize the negative impact of analytical procedures in the environment, which can be considered both at close (to ensure the safety of the analysts) and global (to conserve our natural resources) levels. These principles suggest, among other guidelines, the reduction/minimization of the sample treatment and the use of renewable sources when possible. The first aspect is largely fulfilled by microextraction, which is considered to be among the greenest sample treatment techniques. The second consideration is attainable if natural products are used as raw materials for the preparation of new extraction phases. This strategy is in line with the change in our production system, which is being gradually moved from a linear model (take-make-dispose) to a circular one (including reusing and recycling as key terms). This article reviews the potential of natural products as sorbents in extraction and microextraction techniques from the synergic perspectives of two research groups working on the topic. The article covers the use of unmodified natural materials and the modified ones (although the latter has a less green character) to draw a general picture of the usefulness of the materials.Separations 2020, 7, 2 2 of 22 principle identifies one of the trends of current research in analytical sciences, it is difficult to be applied when complex samples containing the analytes at very low concentrations are processed. In such scenarios, the simplification of the sample treatment and the reduction of the sources applied (reagents, energy) can be a more practical objective, at least currently. Microextraction techniques fulfill the latter criteria [8], and they are considered among the greenest sample treatment techniques [9].Microextraction techniques have evolved in the last decade following some key trends. Among them, the development of new extraction phases can be highlighted, considering the context of this review article. In this evolution, the tenth (use of renewable resources) and eleventh (replace or remove toxic reagents) principles of GAC are especially relevant [7]. In the liquid microextraction context, environmentally friendly solvents [10,11] such as CyreneTM [12] and deep eutectic solvents [13] are clear examples of this progress.The paradigm of our production system, which up to now has been based on a linear "take-make-dispose" model, is progressively changed to a circular model [14] where reusing, repairing, refurbishing, and recycling appear as key terms. The use of surpluses of natural products as raw materials for the preparation of new sorbents is an interesting contribution of analytical chemistry for changing the production model. This review article, which combines the vision of two research groups working in the topic, tries to draw the general picture of the potential of natural products for the synthesis of new sorptive phases in solid phase extraction and solid phase microextraction. The article will cover strategies with different green characterist...
