“…The maximum adsorption capacity of CVD, MBD, and MVD to the desired composite was determined as 32.84 mg•g −1 , 31.81 mg•g −1 , and 31.15 mg•g −1 , respectively. Finally, the ad(de)sorption experiments' results showed that the synthesized nanocomposite adsorbent has an excellent ability to adsorb cationic dyes after several consecutive cycles [28].…”

The present work describes the effect of Ce3+ ion doping on the structural, morphological, and magnetic properties of spinel manganese ferrite (MnFe2O4) nanocrystallites (NCs) using various instrument techniques. Rare earth element (REE) Cerium (Ce3+) doped MnFe2O4 NCs were prepared by a simple microwave combustion technique. In the present scenario, ferrites are widely used for photocatalytic dye degradation and antibacterial applications. Aiming to achieve this, we prepared Ce3+ doped MnFe2O4 NCs by microwave combustion method and urea as burning agent and the obtained powder samples were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), high resolution scanning electron microscope (HR-SEM), high resolution transmission electron microscope (HR-TEM) and vibration sample magnetometer (VSM) techniques. The pure spinel phase formation was confirmed by XRD analysis. FTIR spectra show two prominent absorption bands under 1000 cm−1, which confirms the formation of the spinel structure. HR-SEM and HR-TEM pictures demonstrated a sphere-shaped morphology and also expose the combination and agglomeration of grains, which are mostly due to the magnetic characteristics of the samples. The magnetic properties of the synthesized MnCexFe2−xO4 (x = 0.0, 0.1, 0.3, and 0.5) NCs were studied by VSM analysis at room temperature (RT) shows ferromagnetic behavior. The photodegradation results showed that MnFe2O4 and Ce doped MnFe2O4 NCs have a higher potential to degrade methylene blue (MB) and the sample MnCe0.3Fe1.7O4 NCs showed superb photocatalytic performance (91.53%) compared to other samples. The antibacterial activities of Gram-positive S. aureus, B. subtilis and Gram-negative K. pneumonia and E. coli were investigated using pure and Ce3+ substituted MnFe2O4 NCs and a higher activity for MnCe0.3Fe1.7O4 NCs than other samples was observed, which indicated that they can be used in biomedical applications.

“…The employed adsorbent reduced the amount of American Dye Manufacturers Institute (ADMI) parameter in dye-containing wastewater from 938 to 224 (76.119 %) and the values of chemical oxygen demand (COD), biological oxygen demand (BOD) and total organic carbon (TOC) were also reduced. [70] Another study reported improvement in adsorption performance of double-network hydrophobic-hydrogel in a mixed system, compared to a single system. [62] This is due to the decreased intensity of dyes in the mixed system, caused by decreased value of λ max (wavelength of maximum absorbance) for each dye.…”

Starch‐based adsorbents have demonstrated excellent potential for the removal of various noxious dyes from wastewater. This review critically evaluates the recent progress in applications of starch‐based adsorbents for the removal of dyes from water. The synthesis methods of starch‐based composites and their effects on physicochemical characteristics of produced adsorbents are discussed. The removal of various dyes by starch‐based adsorbents are described in detail, with emphasis on the effect of key parameters, adsorption mechanism and their reusability potential. The key challenges related to the synthesis and applications of starch‐based adsorbents in water purification are highlighted. Based on the research gaps, recommendations for future research are made. The evaluation of starch‐based adsorbents would contribute to the development of sustainable water treatment options in near future.

“…After mixing the K 2 Cr 2 O 7 solution with a suspension of Chlorella vulgaris ZBS1 cells, samples of the solution were taken for analysis for the content of Cr (VI) ions every 20 min, for 120 min. The effect of temperature on the adsorption equilibrium was investigated by varying the temperature from 298 to 328 K. To study the kinetic behavior of the adsorption process of Cr(VI) from aqueous solutions, kinetic models of pseudo-first order, pseudo-second order, the Morris-Weber model describing intraporous diffusion, and the Elovich model were used; calculations were carried out according to formulas (3, 4 , 5 , and 6) [ 3 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 44 ]:

here, q t and q e are the adsorption capacity of Cr (VI) per gram of adsorbent (mg/g), k 1 (1/min)—the constant adsorption rate, k 2 (g/mg·min)—the constant quasi-square velocity of the kinetic model. K int —the constant diffusion rate inside the particles, C i —corresponds to the effects of the boundary layer, α—the initial adsorption rate (mg/g· min), β—the desorption constant (g/mg).…”
