Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°22 (Novembre 2008) . - p. 8888–8893 Titre : New cuprous adsorbent prepared by a bioreduction method for SO2 removal at low temperature Type de document : texte imprimé Auteurs : Lishan Jia, Auteur ; Hao Song, Auteur ; Qingbiao Li, Auteur ; Weiping Fang, Auteur Année de publication : 2008 Article en page(s) : p. 8888–8893 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Bioreduction  Method  SO2 Résumé : A new cuprous adsorbent was prepared by bioreduction method with biomass R08 and its desulfurization ability and regenerative property at low temperature were studied. The results indicated that the amount of SO2 adsorbed on the adsorbent was lower than that on Cu/γ-Al2O3 prepared by chemical method at low temperature; however, it can be easily regenerated and the regenerative adsorbent still has a good SO2 adsorption ability, higher than 87% of that in fresh adsorbent after six regenerations. XPS and FTIR analysis showed that biomass can reduce Cu2+ to Cu+ by aldose and keep the valence of copper exposed to O2 and H2O atmosphere. Furthermore, SO2 is adsorbed on the sorbent with chemical complexation bonds so that it can be desorbed by increasing temperature which is different from γ-Al2O3, Cu(II)/γ-Al2O3 and Cu(I)/γ-Al2O3 that sulfate species are formed.

Optimization of green synthesis of potassium diformate and its potential as a mold Iinhibitor for animal feed / Wenshuang Lin in Industrial & engineering chemistry research, Vol. 49 N° 13 (Juillet 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 13 (Juillet 2010) . - pp. 5981–5985 Titre : Optimization of green synthesis of potassium diformate and its potential as a mold Iinhibitor for animal feed Type de document : texte imprimé Auteurs : Wenshuang Lin, Auteur ; Huixuan Wang, Auteur ; Qingbiao Li, Auteur Année de publication : 2010 Article en page(s) : pp. 5981–5985 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Potassium  diformate Résumé : Potassium diformate (KDF) has been regarded as an alternative to antibiotic growth promoters for animals. This paper delineates a 100% atom economical process for the preparation of KDF from formic acid and potassium formate. Parametric optimization of the synthesis was conducted with respect to reaction time, reaction temperature, and molar ratio of the reactants by employing orthogonal design of experiment method. The results manifested a molar ratio of HCOOH to HCOOK of 1.3, reaction temperature of 65 °C, and reaction time of 30 min as the optimal conditions with a KDF product yield of 94.0%. Efforts were also made to explore the antimold performance of KDF on animal feed using the plate count method. Compared with sodium diacetate (SDA), the widely used mold inhibitor, KDF exhibited even better antimold performance for animal feed. To our knowledge, this work first proved the applicability of KDF as a mold inhibitor for animal feed.

Synthesis of gold nanoplates with bioreducing agent using syringe pumps / Guowu Zhan in Industrial & engineering chemistry research, Vol. 51 N° 48 (Décembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 48 (Décembre 2012) . - pp. 15753-15762 Titre : Synthesis of gold nanoplates with bioreducing agent using syringe pumps : A kinetic control Type de document : texte imprimé Auteurs : Guowu Zhan, Auteur ; Lanting Ke, Auteur ; Qingbiao Li, Auteur Année de publication : 2013 Article en page(s) : pp. 15753-15762 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Kinetics  Pump Résumé : Anisotropic Au nanoplates are particularly important owing to their unusual properties. Herein, we describe a plant-mediated bioreduction method to increase the yield of Au nanoplates and shorten the reaction time through a kinetically manipulated procedure. More specifically, the reduction rate was controlled by modulating experimental factors such as the addition mode and rate of the feed solutions, the temperature, and the pH based on a syringe-pumps apparatus. The dimensions of the obtained Au nanoplates were measured using TEM and AFM. The single-crystalline structure was demonstrated by HRTEM, SAED, and XRD. The results of XPS, FTIR, and TG analyses indicated strong affinity of the biomolecules binding to the Au nanoplate facets. In particular, the nanoplate films exhibited strong surface plasmon absorbance in the near-infrared range of 700―3000 nm, vital for optical applications. Furthermore, we propose a mechanism for this formation following the time-resolved studies.
