Magnetic Nanoparticles Impregnated, Cross-Linked, Porous Chitosan Microspheres for Efficient Adsorption of Methylene Blue from Pharmaceutical Waste Water

The study demonstrates the preparation of MnFe2O4 impregnated chitosan-microspheres (CMMS) as adsorbents for efficient removal of cationic thiazine dye, methylene blue. A facile approach with great economic and technical advantages to obtain highly crystalline manganese ferrite nanoparticles by solution combustion method is accounted. CMMS were characterized and evaluated for MB adsorption using linear forms of Freundlich and Langmuir adsorption isotherms, pseudo-first order, pseudo-second order and Elovich kinetic models. Application of CMMS to pharmaceutical waste, desorption of MB and reusability of CMMS are reported. Significantly, MB concentration in treated real sample was reduced by similar to 18 times to that of initial concentration.

Novel Maillard Pigment, Furpenthiazinate, Having Furan and Cyclopentathiazine Rings Formed by Acid Hydrolysis of Protein in the Presence of Xylose or by Reaction between Cysteine and Furfural under Strongly Acidic Conditions

A novel Maillard pigment having partial structures of furan and cyclopentathiazine, named furpenthiazinate, was isolated and identified. Although this pigment was found in an acid hydrolysate of a Maillard reaction solution between soy protein and xylose, the same pigment was also formed by the Maillard reaction under strongly acidic conditions between soy protein and xylose and cysteine and furfural. The structure of its reduced form by NaBH4 was determined by MS, NMR, and X-ray analysis and identified as 7-(2-furany1)-2,3,4,4a,5,6-hexahydrocyclopenta[b][1,4]thiazin-4-ium-3-carboxylate, indicating that the chemical structure of furpenthiazinate is 7-(2-furanyl)-2,3,5,6-tetrahydrocyclopenta[b][1,4]thiazine-3-carboxylic acid. Furpenthiazinate showed an absorption maximum at 400 nm and strong yellow color under acidic and neutral conditions. The color contribution of furpenthiazinate was estimated to be more than 60% in a reaction solution prepared from cysteine and furfural.

Media polarity and concentration roles on the third order nonlinear behaviors of thiazine dyes

Nonlinear optical materials play important roles in optics and photonics. In order to improve the performance of these materials, in this paper, we tried to find effective methods for controlling the nonlinear responses of thiazine dyes. Our experimental results indicate that molecular linear properties, media polarity, concentration and excitation beam properties with different contributions play significant roles on the saturable and reverse saturable absorption characteristics of thiazine dyes. In real, competition between these effective parameters leads to appearance of various third order nonlinear responses. Although by excitation wavelengths near the absorption peaks and at high powers, dye molecules tend to indicate reverse saturable absorption characteristics in polar protic solvents by increasing the concentration, saturable absorption characteristics were observed in polar aprotic solvents. Furthermore, the samples displayed the same behaviors in different solvent media at low powers and for excitation wavelengths far from absorption peaks. Therefore, by controlling the nonlinear responses of thiazine dyes, these materials can indicate both saturable and reverse saturable absorption characteristics that increase their applications in optics and photonics devices.

Dye affinity chromatography for fast and simple purification of fucoidan from marine brown algae

Fucoidan is a sulfated polysaccharide with promising pharmacological applications. Due to its medicinal properties, there is a demand for a separation technique that yields a high purification grade. Here, we present a novel purification tool for recovering fucoidan from the marine brown macroalgae Fucus vesiculosus. The developed method is based on amino-derivatized Sepabeads (R) EC-EA. The beads were modified with toluidine blue (TB), a thiazine derivative, to exploit the strong donor acceptor interactions between the cationic dye and the anionic polysaccharide. The adsorption kinetics and the binding capacity of the resin were analyzed. A Sips model was used to approximate the adsorption isotherm, resulting in a maximum capacity of 127.7 mg fucoidan per g adsorbent. Investigation of the effect of adsorption step’s pH on purity and chemical structure was performed by TB and Fourier transform infra-red spectroscopy assays. Results showed that adsorption at pH 1 and 6 had negligible effects on fucoidan’s chemical structure. However, purity was actually improved by 1.55- and 1.69-fold at pH 1 and 6, respectively, with an average yield of 5 g/100 g dried algae powder. In contrast, only a 1.46-fold increment was observed in fucoidan purified by the traditional method at pH 2, with a yield of 7.5 g/100 g dried algae powder. Furthermore, fucoidan purified by this method at pH 6 complies with, or even exceeds the quality of the commercially available (>= 95% pure) fucoidan (Sigma-Aldrich (R)) with respect to molecular weight and sulfur content. Therefore, dye affinity chromatography provides more advantages than the classically used techniques for fucoidan purification.
