1. Synthesis of a novel polysuccinimide based resin for the ultrahigh removal of anionic azo dyes from aqueous solution
Muhammad Mansha, Abdul Waheed, Tauqir Ahmad, Izzat Wajih Kazi, Nisar Ullah Environ Res. 2020 May;184:109337. doi: 10.1016/j.envres.2020.109337. Epub 2020 Mar 3.
A novel hyper-cross-linked polyamide resin (PSI-PA) has been synthesized for the ultrahigh removal of Congo red (CR) and Eriochrom Black T (EBT) from aqueous solution. The mesoporous resin, having a specific surface area (98.80 m2 g-1), showed maximum adsorption capacity (Qmax) of 522.18 mg g-1 for CR (pH 9.0) and 460.34 mg g-1 for EBT (pH 6) at room temperature. The adsorption of these dyes was rapid and the equilibrium was attained within 4 h. The kinetic data was well-fitted by pseudo-second-order rate equation. Analysis of the surface chemical composition of loaded PSI-PA by XPS revealed the appearance of a new peak at around 166.0 eV (S 2p), confirming the adsorption of the sulfur-based dyes onto the resin. Examination of experimental data of dyes adsorption by a variety of non-linear adsorption isotherms and kinetic models suggested that the Langmuir model exhibited the best fit with high correlation coefficients for both CR (R2 = 0.9966) and EBT (R2 = 0.9934). PSI-PA has been extensively characterized by FT-IR, solid state 13C (CP-MAS) NMR, EDS, TGA and BET analysis. Moreover, PSI-PA exhibited 82% removal efficiency for dyes in simulated effluents, manifesting its promise and utility for treating industrial effluent.
2. A new method for determination of cocamidopropyl betaine synthesized from coconut oil through spectral shift of Eriochrome Black T
Ali Gholami, Mahshid Golestaneh, Zeinab Andalib Spectrochim Acta A Mol Biomol Spectrosc. 2018 Mar 5;192:122-127. doi: 10.1016/j.saa.2017.11.007. Epub 2017 Nov 10.
Cocamidopropyl betaine (CAPB) is a zwitterionic surfactant that is synthesized using coconut oil and usually supplied in form of an aqueous solution with 25-37% w/w. In this study, a novel method based on UV-visible spectroscopy is developed for an accurate determination of CAPB synthesized from coconut oil. Eriochrome Black T (EBT) as a specific color indicator was added to CAPB and a red shift and color change were observed. This shift leads in increasing wavelength selectivity of the method. The change in the color intensity depends on the concentration of CAPB. By measuring the absorbance of a solution containing CAPB, its concentration was measured. After optimizing all the effective parameters, CAPB was detected in commercial real samples. Using the proposed approach, limit of quantification (LOQ) and relative standard deviation (RSD) were obtained about 4.30×10-5M and 4.8% respectively. None of unreacted materials or by-products, which were produced in the synthesis of CAPB, showed any interference in the determination of CAPB. This shows that the proposed method is specific and accurate, and can potentially be used for quantitative determination of CAPB in commercial samples with satisfactory results.
3. Degradation of the phenolic β-ether lignin model dimer and dyes by dye-decolorizing peroxidase from Bacillus amyloliquefaciens
Juan Yang, Tongguo Gao, Yaru Zhang, Shuo Wang, Hongya Li, Shuna Li, Shuxiang Wang Biotechnol Lett. 2019 Sep;41(8-9):1015-1021. doi: 10.1007/s10529-019-02696-0. Epub 2019 May 27.
Objective: The dye-decolorizing peroxidase from Bacillus amyloliquefaciens, BaDyP, was identified to be an efficient catalyst for the degradation of phenolic β-ether lignin model dimer guaiacylglycerol-β-guaiacyl ether (GGE) and dyes. Results: Efeb gene encoding BaDyP from B. amyloliquefaciens MN-13 consisted of 1257 bp and the open reading frame encoded 418 amino acids. The efeb gene was expressed in Escherichia coli BL21 and a recombinant BaDyP of 50 kDa was achieved. The BaDyP exhibited activity in oxidizing GGE and decolorizing azo and triphenylmethane dyes. At pH 4.5 and 30 °C the BaDyP not only completely degraded GGE by the cleavage of β-O-4 ether bond and Cα-Cβ bond, and Cα oxidation without any oxidative mediator, but also decolorized four synthetic dyes, including congo red, bromine cresol green, eriochrome black T and crystal violet. This was achieved with decolorization rates of 65.7%, 70.62%, 80.06% and 62.09%, respectively, after 72 h of incubation. Conclusions: BaDyP was identified as a bacteria peroxidase with great potential for the degradation of lignin and bioremediation of dye-contamination.
