“…3 revealed that the percentage removal of Orange 2G dye is gradually increased by time and reached a steady state after 12 h of contact time. As can be clearly seen from Table-4, the values of Qe that were calculated using pseudo-second order model were closer to the experimental one than using the first order model, assuming that chemisorption process has been taken out and the given data were suitably fitted with pseudosecond order kinetic model [23]. …”

In the current study, the removal of Orange 2G dye founded in aqueous solutions using titanium dioxide-based nanoparticles has been investigated. Titanium dioxide nanoparticles were successfully prepared using tetrabutyl ammonium bromide (TTAB) as a surfactant by sol-gel method and characterized by X-ray diffraction, BET surface area, IR and TEM spectroscopy. The experimental data is most fitting with Freundlich isotherm model indicating heterogeneity of sorbent surface. Langmuir data revealed that the maximum removal capacity of Orange 2G equals to 85.47 mg g -1 . Kinetic studies disclosed that intraparticle diffusion is not the only rate-determining step and the removal process is organized by a chemical reaction as well.

“…The ionic radius for Tb 3+ is 106.3 pm while 115 pm for La 3+ . The stability of the forming complex is anticipated to be less convenient for species of bigger extent; this is reliable with previous research [ 17 , 34 – 36 ].…”

Lanthanide metal ions make distinctive and essential contributions to recent global proficiency. Extraction and reuse of these ions is of immense significance especially when the supply is restricted. In light of sorption technology, poly(amidoxime-hydroxamic) acid sorbents are synthesized and utilized for the removal of various lanthanide ions (La3+, Nd3+, Sm3+, Gd3+, and Tb3+) from aqueous solutions. The sorption speed of trivalent lanthanides (Ln3+) depending on the contact period is studied by a batch equilibrium method. The results reveal fast rates of metal ion uptake with highest percentage being achieved after 15–30 min. The interaction of poly(amidoxime-hydroxamic) acid sorbent with Ln3+ ions follows the pseudo-second-order kinetic model with a correlation coefficient R2 extremely high and close to unity. Intraparticle diffusion data provide three linear plots indicating that the sorption process is affected by two or more steps, and the intraparticle diffusion rate constants are raised among reduction of ionic radius of the studied lanthanides.

“…Iminodiacetate (IDA) is a common transition-metal-chelating ligand that has been utilized in commercial chelating resins for heavy-metal removal from water − and immobilized onto a variety of materials for ion and protein separation applications. − ,− IDA is a tridentate metal chelator with a total of three metal chelating sites, two carboxylates and a tertiary amine. Its high affinity for iron (log K = 10.72 for Fe 3+ ) and copper (log K = 10.57 for Cu 2+ ), and low stability constant for other multivalent ions common in food, such as calcium (log K = 2.59 for Ca 2+ ) and magnesium (log K = 2.98 Mg 2+ ), support its specificity toward transition metals responsible for oxidative degradation in foods.…”

The introduction of metal-chelating ligands to the food-contact surface of packaging materials may enable the removal of synthetic chelators (e.g., ethylenediamine tetra-acetic acid (EDTA)) from food products. In this study, the metal-chelating ligand iminodiacetate (IDA) was covalently grafted onto polypropylene surfaces to produce metal-chelating active-packaging films. The resulting films were able to chelate 138.1 ± 26 and 210.0 ± 28 nmol/cm(2) Fe(3+) and Cu(2+) ions, respectively, under acidic conditions (pH 3.0). The films demonstrated potent antioxidant efficacy in two model food systems. In an emulsified-oil system, the chelating materials extended the lag phase of both lipid hydroperoxide and hexanal formation from 5 to 25 days and were as effective as EDTA. The degradation half-life of ascorbic acid in an aqueous solution was extended from 5 to 14 days. This work demonstrates the potential application of surface-grafted chelating IDA ligands as effective antioxidant active food-packaging materials.
