“…The reason behind the unique magnetic properties of the prepared SPIONs may be their tiny size. 47,48 The magnetization saturation of the adsorbent (69.47 emu g −1 ) is higher than that of the SPIONs (74.92 emu g −1 ), indicating that coating the SPIONs with the as-prepared AD did not affect their magnetic strength. Therefore, the obtained ADFS can be easily separated from the solution by an external magnetic field.…”

“…Adsorbents/catalysts to remove these are highly important, which can be obtained from biological sources 9 . SPIONs are much utilized nanoparticles for effective removal of these dyes 10 , the efficiency could be increased while coating with a biopolymer, where Samrot et al 11 found chitosan coated SPIONs to remove chromium efficiently than the naked SPIONs.…”

Latex, a milky substance found in a variety of plants which is a natural source of biologically active compounds. In this study, Latex was collected from raw Carica papaya and was characterized using UV–Vis, FTIR and GC–MS analyses. Super Paramagnetic Iron Oxide Nanoparticles (SPIONs) were synthesized, coated with C. papaya latex (PL-Sp) and characterized using UV–Vis, FT-IR, SEM–EDX, XRD, VSM and Zeta potential analyses. SPIONs and latex coated SPIONs (PL-Sp) were used in batch adsorption study for effective removal of Methylene blue (MB) dye, where (PL-Sp) removed MB dye effectively. Further the PL-Sp was used to produce a nanoconjugate loaded with curcumin and it was characterized using UV–Vis spectrophotometer, FT-IR, SEM–EDX, XRD, VSM and Zeta potential. It showed a sustained drug release pattern and also found to have good antibacterial and anticancer activity.

“…Dyes concentrations were determined by double-beam spectrophotometer (JENWAY 6800 UV/VIS). Crystal violet was measured at wavelength 590 nm [26], methylene blue at 664 nm [27] and methyl orange at 463 nm [28]. The adsorbed quantity of dyes expressed as (q eq ) and the removal percent detected on the word of the following (Eq.1&2) respectively:…”

Organic dyes are major elements in wastewater effluents, caused serious environmental damage and human health dangers for that we use of factorial design software to evaluate efficiently factors influencing the adsorption capacity of iron oxide nanoparticles alginate beads (SP-IONPs-ALG) to remove crystal violet (CV), methylene blue (MB) and methyl orange (MO) from aqueous solution. The current work included prepared SP-IONPs-ALG by using green synthesized iron oxide nanoparticles (IONPs) using Spirulina platensis, then coated by alginate. SP-IONPs-ALG characterized by using EDX and SEM then used it as adsorbent for uptake CV, MB and MO from aqueous solution. A 2 4 (CCD) based on single-factor experiments and a four-variables, pH (x 1 ), interaction time (x 2 ), dyes conc. (x 3 ) and sorbent dosage (x 4 ) used to evaluate efficiency of SP-IONPs-ALG for adsorption of CV, MB and MO from aqueous solution. The outlined results inferred that pH, contact time and adsorbent dosage had positive effect in dyes remove with high removal percentage for CV, MB and MO (93.46%, 96.47% and 94.4%; respectively). Freundlich model was fitting for description adsorption of CV & MB with maximum adsorption capacity (Q max ) 344.82 mg g -1 , 416.6 mg g -1 respectively but Langmuir isotherm model more fit to describe the experimental data for representing the adsorption process of MO with maximum adsorption capacity 370.3 mg g -1 . The kinetic model fitted well with a pseudo second order rate equation. Furthermore, the reusability of SP-IONPs-ALG was successfully achieved by using HCl and NaOH for (CV & MB) and MO, respectively. Keywords Iron, nanoparticles, Spirulina platensis, alginate beads, crystal violet and dyes removal.
