Sustainable adsorptive removal of antibiotics from aqueous streams using Fe3O4-functionalized MIL101(Fe) chitosan composite beads

One-Step Synthesis of a Mn-Doped Fe2O3/GO Core–Shell Nanocomposite and Its Application for the Adsorption of Levofloxacin in Aqueous Solution

“…The linear equations (eqs S4–S6, Supporting Information, Sub-section 1.2) were used to study these models, and the attained pseudo-first-order and pseudo-2nd-order kinetic parameters are demonstrated in Table . It can be seen that the obtained data evidently show a good fit for the pseudo-second-order model for all Lev tested concentrations, as confirmed by the higher regression coefficient values ( R 2 > 0.993) when compared to the pseudo-first-order model, suggesting an electrostatic interaction mechanism. , Additionally, the calculated adsorption capacity ( q e ) values of the pseudo-second-order kinetic model were closer to the experimental q e values. These findings suggest that the overall Lev adsorption was dominated by the electrostatic processes involving ion exchange forces, in accordance with the assumption of the pseudo-second-order kinetic model …”

“…The use of antibiotics to treat infectious diseases, such as chlamydia, malaria, urinary tract infections, etc., results in drug resistance in pathogenic bacteria in human beings and livestock. , However, antibiotics are regarded as persistent organic contaminants because of their incessant rapid increase in various water bodies. − Moreover, antibiotics are unmetabolized or partially metabolized, causing the release of metastable cyclic functional moieties such as benzene, piperazine, sulfonamides, morpholine, quinolone, and hexahydro-pyrimidines to the environment . Therefore, contamination of drinking water by antibiotics has become a serious environmental concern as these contaminations can cause serious health risks such as headaches, nausea, diarrhea, nervousness, allergic reactions, etc …”

Preparation of magnetic metal‐organic framework MIL‐101(Fe) and its application in the extraction of anthraquinones in rhubarb

“…Its ligand is terephthalic acid, which can adsorb different substances through hydrogen bonding, electrostatic interaction, and so on [20]. At present, MIL-101based MSPE has been applied in various fields, including the determination of drugs such as antibiotics [21] and non-steroidal anti-inflammatory drugs [22], endocrine substances such as phthalate esters [23], pesticides such as organochlorine pesticides [24], triazine herbicides [25][26], common pollutants such as organic dyes [27][28][29][30], as well as toxins such as ochratoxin A [31]. It is no doubt that the use of MSPE for qualitative or quantitative analysis of trace compounds from different complex sample matrices is significant for phytochemical analysis.…”
