Sodium arsenate, the main component of arsenic-containing solid waste pollutants, causes serious environmental health threats. Crystallization is one of the effective methods for separating and purifying sodium arsenate from arsenic-alkali residue lixivium. However, the crystallization process is limited for its low observability and the lack of separation and purification data. In this work, a laser detection system with a magnetic field generator was designed, and the solubility, metastable zone width, interfacial tension, interfacial entropy factor, crystal nucleation, and growth rate of sodium arsenate were investigated in a constant composition environment. The results showed that the solubility, metastable zone width, interfacial tension, and interfacial entropy factor decreases with the presence of a magnetic field. The magnetic field shortened the crystallization induction time and changed the nucleation and growth rate of sodium arsenate. Under the magnetic field, the nucleation rate increased from 2.43 × 10 16 to 8.98 × 10 17 (s m 3 ) −1 , and the growth rate decreased from 4.94 × 10 −8 to 2.73 × 10 −8 (s m 3 ) −1 , the growth mechanism of sodium arsenate as a continuous growth mode was unchanged. In addition, the X-ray diffraction and infrared showed that the crystal structure of sodium arsenate is unaffected by the magnetic field, indicating that the enhancement of the crystallization process of sodium arsenate with the magnetic field could be a feasible method in engineering application.

“…Zinc plays an important regulatory role in normal physiological functions such as reproduction, and it is critical to the functioning of the nervous, immune, and endocrine systems. Similarly, as a special amino acid with a sulfur‐content nonprotein structure, taurine (2‐aminoethanesulfonic acid, C 2 H 7 NO 3 S) is mainly distributed in some excitable tissues, such as the liver, central nervous system, retina, heart, and skeletal muscle (Han & Chesney, ; Kawagishi et al., ; Wu et al., ). More importantly, taurine functions as an antitumor, anti‐oxidant, and anti‐arrhythmia compound, and it protects the liver, improves the gallbladder, and regulates blood pressure (Bircan, Balabanli, Turkozkan, & Ozan, ; Ijiri et al., ; Ozden et al., ; Sun, Zhao, Gu, & Xu, ).…”

Recently, intensive processing of marine resources has attracted considerable attention. In order to further utilize the byproducts of aquatic shellfish (Pinctada martensii meat) with high value, this study proposes a method of extracting zinc and taurine from P. martensii meat. Zinc was first extracted from P. martensii meat with an ultrasonic crusher, and then taurine was further extracted by ultrasonic-assisted water extraction from the remaining shellfish. After optimization, the biological zinc extraction rate reached 8.63%, and the taurine extraction rate reached 0.71%. Meanwhile, the parameters for cation exchange separation and taurine purification were optimized, in which the injection volume, pH value, and elution rate were set to 8.0 mL, 4.5, and 3.0 mL/min, respectively. Ultimately, the purity the extracted taurine reached 98.16%. This study provides a novel method for the extraction of biological zinc and taurine by deep processing of shellfish meat.

BACKGROUND: 5-hydroxymethylfurfural (HMF) and 5-ethoxymethylfurfural (EMF) are biomass-based value-added chemicals. Various catalytic systems have been studied for converting fructose into HMF and EMF. A more efficient and stable solid acid catalyst is highly desirable for the conversion process. RESULTS: In this study, a novel taurine-involved Ce metal organic framework material (T-CeMOF) was synthesized by coordinating Ce to 1,3,5-benzenetricarboxylic acid (BTC) in the presence of taurine. T-CeMOF was analyzed with Fourier-transform infrared (FTIR) spectroscopy, transmission electron microscoy (TEM), and nitrogen adsorption-desorption analysis. Results showed that the presence of taurine makes T-CeMOF have a much larger specific pore volume than Ce based metal-organic framwork (CeMOF), which was synthesized by coordinating Ce with the ligand BTC in absence of taurine. It is implied that T-CeMOF has many more swinging carboxyl groups on the surface than CeMOF. In addition, the sulfonic acid group of taurine is introduced into T-CeMOF. All of these contribute toward making sure that T-CeMOF is effective for the conversion of fructose to HMF and EMF in ethanol. Under the catalysis of T-CeMOF, the total yield of HMF and EMF reached 78.4% within 1 h. T-CeMOF could be recycled and the catalytic activity of the catalyst was maintained after five cycles. CONCLUSION: T-CeMOF can be synthesized at room temperature and it achieved a high total yield of HMF and EMF in ethanol within 1 h. T-CeMOF opens a new route for one-pot conversion of abundant and cheap fructose-based biomass into promising biochemicals.
