“…Overall, the Ms (magnetization saturation) value was still lower (93 emu•g −1 ) than bulk Fe 2 O 3, which might be due to the increase in surface area during manganese modification and surface bonding on biochar, according to previous observation. [50][51][52][53] The magnetization behavior in MF-BC could be due to formation of iron oxides during pretreatment and fabrication.…”

BACKGROUND: In the current work, the conventional pyrolysis technique was replaced by new concentrated solar power (CSP) driven technique to fabricate and modify biochar (BC) for more sustainable, energy independent, cost-effective, and ecofriendly pyrolysis processes. Double-glazed vacuum tube was used as a reactor for pyrolysis along with solar tracking system on CSP plant, meanwhile nitrogen flow was maintained during pyrolysis to create an inert environment. Further, a novel approach was used to modifying BC by loading bimetal oxide (Mn-Ferrite) on pristine biochar (P-BC) using pre-and posttreatment to enhance its sorption capacity for anionic aromatic pollutant i.e., Eriochromie Black T (EBT) dye from aqueous solution. RESULTS: Ferric chloride hexahydrate (FeCl3•6H 2 O) and Ferrous sulfate heptahydrate (FeSo 4 •7H 2 O) were used to develop magnetic nanoparticles (MNPs) γ-Fe 2 O 3 by co-precipitation technique. Both Biomass and P-BC were treated with MnCl 2 •4H 2 O and MNPs to fabricate an innovative bi-metal oxide (MnFe 2 O 4 ) biochar. The characterization of modified biochars via Elemental analyzer, SEM (scanning-electron-microscopy), BET (Brunauer-Emmet-Teller), XPS (X-ray-photoelectron-spectroscopy), FTIR (Fourier-transform-infrared-spectra), and VSM (Vibrating-sample-magnetometer), ensured the loading of magnetic bimetal oxide over P-BC. Various kinetic and isotherm models were employed from which pseudo-second-order have proven to be the best fit kinetic model on all types of BCs with highest correlation coefficient value (R 2 = 0.999). While among isotherm models, Langmuir demonstrated best regression coefficient (R 2 = 0.98) and Qmax for EBT was up to 121.95 mg•g −1 .CONCLUSIONS: Altogether, the results indicated that innovative Mn-ferrite loaded BC has better sorption ability to EBT than simple metal oxide of Mn and Fe.

“…However, there are deficiencies apparent in the recovery, separation, and reuse of heavy metal adsorbents. The magnetic nanomaterial makes up for these deficiencies to a certain extent owing to the easy phase separation after treatment (Moazzen et al, 2019;Venkateswarlu et al, 2015;Wei et al, 2012). Among many nano-magnetic materials, magnetic Fe 3 O 4 is the most common and widely used, which can achieve magnetic separation in a short time under the action of an external magnetic field (Zhang et al, 2013).…”

A Review: Adsorption and Removal of Heavy Metals Based on Polyamide-amines Composites

et al. 2022

In recent years, the problem of heavy metal pollution has become increasingly prominent, so it is urgent to develop new heavy metal adsorption materials. Compared with many adsorbents, the polyamide-amine dendrimers (PAMAMs) have attracted extensive attention of researchers due to its advantages of macro-molecular cavity, abundant surface functional groups, non-toxicity, high efficiency and easy modification. But in fact, it is not very suitable as an adsorbent because of its solubility and difficulty in separation, which also limits its application in environmental remediation. Therefore, in order to make up for the shortcomings of this material to a certain extent, the synthesis and development of polymer composite materials based on PAMAMs are increasingly prominent in the direction of solving heavy metal pollution. In this paper, the application of composites based on PAMAMs and inorganic or organic components in the adsorption of heavy metal ions is reviewed. Finally, the prospects and challenges of PAMAMs composites for removal of heavy metal ions in water environment are discussed.

Death from tuberculosis has resulted in an increased need for early detection to prevent a tuberculosis (TB) epidemic, especially in closed and crowded populations. Herein, a sensitive electrochemical DNA biosensor based on functionalized iron oxide with mercaptopropionic acid (MPA-Fe3O4) nanoparticle and nanocellulose crystalline functionalized cetyl trimethyl ammonium bromide (NCC/CTAB) has been fabricated for the detection of Mycobacterium tuberculosis (MTB). In this study, a simple drop cast method was applied to deposit solution of MPA-Fe3O4/NCC/CTAB onto the surface of the screen-printed carbon electrode (SPCE). Then, a specific sequence of MTB DNA probe was immobilized onto a modified SPCE surface by using the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide (EDC/NHS) coupling mechanism. For better signal amplification and electrochemical response, ruthenium bipyridyl Ru(bpy)32+ was assigned as labels of hybridization followed by the characteristic test using differential pulse voltammetry (DPV). The results of this biosensor enable the detection of target DNA until a concentration as low as 7.96 × 10−13 M with a wide detection range from 1.0 × 10−6 to 1.0 × 10−12 M. In addition, the developed biosensor has shown a differentiation between positive and negative MTB samples in real sampel analysis.
