AbstractWe herein report a facile, ‘green’ one- step synthesis of a series of monodispersed water-soluble selenide nanoparticles at room temperature. The capping ligands used include, cysteine, methionine, ascorbic acid and starch which function as agents of solubilisation, stabilization and conjugation sites for biomolecules. The synthetic approach involves the addition of an appropriate volume of selenide ion produced via the reduction of selenium powder in water to an aqueous solution containing the ligand- metal salt (MCl2 M = Zn or Cd). Optical spectroscopy shows that the particles are of high quality while the transmission electron microscopy (TEM) of the samples shows variation in shapes ranging from dots to rods of high and low aspect ratios.

Significant Factors

Background: Zeolitic imidazolate frameworks with three metals Zn, Co and Ag (ZIF-3M) and ZIF-67 were synthesized at room temperature and characterized with different techniques such as FESEM, BET, EDX and XRD. Then, the synthesized nanoparticles were successfully applied for the removal of levofloxacin from aqueous solutions. Methods: To optimize the significant factors (i.e., pH, adsorbent dose and contact time), the response surface methodology (RSM) was implemented based on Box-Behnken design (BBD) in each step, an appropriate amount of adsorbent was added to 30 ppm of a solution containing levofloxacin and the pH was adjusted to the desired value with 0.1 M HCl or 0.1 M NaOH. The mixture was stirred at room temperature and then centrifuged at 7500 rpm for 3 min. Results: The optimal conditions for each variable were performed using Box-Behnken design. Results revealed that ZIF-3M nanoparticles more efficiently remove levofloxacin than ZIF-67 in aqueous solution. Conclusion: In this research, new three metals ZIF (ZIF-3M) nanoparticles were synthesized with Ag, Zn and Co in aqueous solution and characterized by different techniques. Results indicated successful synthesis with preserving ZIF framework. Results indicated that ZIF-3M has more ability for the removal of levofloxacin than ZIF-67. Isotherm studies showed that the most suitable model for the adsorption of levofloxacin onto ZIF-3M has a good agreement with the Langmuier model.

The phospha-Brook rearrangement of dialkyl 1-aryl-1-hydroxymethylphosphonates (HPs) to the corresponding benzyl phosphates (BPs) has been elaborated under solid-liquid phase transfer catalytic conditions. The best procedure involved the use of triethylbenzylammonium chloride as the catalyst and Cs2CO3 as the base in acetonitrile as the solvent at room temperature. The substrate dependence of the rearrangement has been studied, and the mechanism of the transformation under discussion was explored by quantum chemical calculations. The key intermediate is an oxaphosphirane. The one-pot version starting with the Pudovik reaction has also been developed. The conditions of this tandem transformation were the same, as those for the one-step HP→BP conversion.
