“…Unlike what occurs with pristine graphene oxide in water, which, even at low concentrations, can cause phytotoxicity in cabbage, tomatoes, red spinach, and lettuce [37]. As in this study, Fraga et al [26] did not observe inhibitory effects when using an iron-based GO adsorbent in the treatment of textile effluents, as the seeds of Lactuca sativa L. presented a growth of 95% of the seeds at different dilutions. Likewise, Da Silva et al [67] did not observe potential phytosociological effects in their effluent after treatment with an amino-iron-functionalized graphene oxide nanocomposite.…”

“…4b shows the results regarding the non-linear fittings to Langmuir and Langmuir-Freundlich equations of natural clay and organoclay A. Table III presents the data for the nonlinear adjustments to the proposed models, which show that equilibrium data was satisfactorily adjusted to Langmuir-Freundlich isotherm, indicating heterogeneous regions on the adsorbent surface and interactions with variable energy [25]. The superior coefficient of determination (R 2 ) and lesser residual sum of squares (rss) confirmed this physicalchemical behavior.…”

The main goal of this research was to study the adsorptive capacity of an organophilic clay for the removal of textile dye Nylosan blue B113 and its further application in real textile effluent (RTE) treatment. The used clay known as Bofe was originated in the township of Boa Vista, State of Paraíba, Northeast of Brazil. Initially, the material was dried and powdered. Subsequently, the organophilic clay was synthesized by insertion of hexadecyltrimethylammonium bromide. Furthermore, the clay was characterized using the following analyses: cation exchange capacity (CEC), X-ray diffractometry (XRD), surface area analysis, and pH of point of zero charge (pH pzc ). Then, batch adsorption systems were performed along with equilibrium/kinetic/thermodynamic studies. At last, keeping the same weight/volume ratio, a solution of real textile effluent was treated. Results showed CEC of 54.40 mmol/100g, lamellar expansion from 1.69 to 2.01 nm, maximum adsorptive capacity of 50 mg.g -1 , and chemical oxygen demand (COD) removal of 74% (RTE).

“…Similarly, the order of adsorption for rhodamine B and methyl orange removal by Fe 3 O 4 nanoparticles-functionalized activated carbon obtained from the pseudo- n -order model varied from 1 to 2 and was closer to 2 [ 8 ]. On the contrary, Fraga et al [ 27 ] observed the great value of n (7.46) for the adsorption of reactive drimaren red by amino-Fe 3 O 4 functionalized multilayer graphene oxide, suggesting a highly heterogeneous interface.…”

Magnetically Functionalized Moss Biomass as Biosorbent for Efficient Co2+ Ions and Thioflavin T Removal

et al. 2020

Microwave synthesized iron oxide nanoparticles and microparticles were used to prepare a magnetically responsive biosorbent from Rhytidiadelphus squarrosus moss for the rapid and efficient removal of Co2+ ions and thioflavin T (TT). The biocomposite was extensively characterized using Fourier transformed infrared (FTIR), XRD, SEM, and EDX techniques. The magnetic biocomposite showed very good adsorption properties toward Co2+ ions and TT e.g., rapid kinetics, high adsorption capacity (218 μmol g−1 for Co and 483 μmol g−1 for TT), fast magnetic separation, and good reusability in four successive adsorption–desorption cycles. Besides the electrostatic attraction between the oxygen functional moieties of the biomass surface and both Co2+ and TT ions, synergistic interaction with the –FeOH groups of iron oxides also participates in adsorption. The obtained results indicate that the magnetically responsive biocomposite can be a suitable, easily separable, and recyclable biosorbent for water purification.
