Abstract ：
难处理金精矿的生物氧化浸出过程是一种新型、低污染、清洁的生产工艺。该生物氧化过程是在气液固三相生物搅拌釜反应器中进行的。在气液固三相生物搅拌釜反应器中,离底悬浮状态具有较低剪应力、较低能耗和较高相间传质系数的特点,是保证生物反应持续高效进行的一个优化条件。为了优化设置搅拌桨离底高度以实现生物氧化浸出反应过程的节能和高效,本文提出了一种通用的计算离底悬浮转速的公式,并采用实验数据进行验证。结果表明:针对精金矿体系气液固三相离底悬浮转速的计算误差低于20%,所提出的公式和研究方法能够快速地确定工程设计的优化参数,以实现节能和减少生物浸出的污染。

Abstract ：
Bio-oxidation technology for leaching sulfide mineral of refractory gold concentrate is cleaner than conventional methods. Although liquid agitation can maintain cells and particles in suspension, thereby improving the mass transfer efficiency of oxygen, carbon dioxide, and nutrients, it also generates shear stress, which can reduce bio-oxidation reaction efficiency by destroying shear sensitive cells. In this study, a multiphase Eulerian model with the standard k-epsilon equation and auxiliary models were evaluated based on previously conducted experiments investigating two and three phase flows of gas-liquid, solid-liquid and gas-liquid-solid. The predicted shear stress on bacteria, gas holdup, bubble diameter and turbulence energy dissipation rate were then calculated by these models to reveal the key factors influencing bio-leaching efficiency and to analyze the primary region in which cell death occurs. The results showed that shear stress on bacteria in the impeller region is higher than in other regions. Based on the results of the study, an optimal operation condition was applied to bio-oxidation technology investigations. Comparing with classic roasting technology, bio-oxidation technology completely eliminates toxic gas emissions, reduces 4.3tons of wastewater per ton of refractory gold concentrate and reduces the leaching toxicity of total arsenic in the solid waste from 0.57 mg/L to 0.36 mg/L. It is demonstrated that bio-oxidation technology is cleaner and more eco-friendly than classic roasting technology. This work provides guidance for further study and designation of the stirred bioreactor scaleup in both biochemical and environmental engineering applications. (C) 2018 Elsevier Ltd.

Abstract ：
A new stable cobalt-organic framework, namely [Co-2(oba)(2)(H(2)Me(4)bPz)](n) (1) (H(2)oba = 4.4'-oxydibenzoic acid, H(2)Me(4)bpz = 3.3',5,5'-tetramethyl-4,4'-bipyrazole), has been synthesized by combining the mixed H(2)oba and H(2)Me(4)bpz with Co(CH3COO)(2)center dot 4H(2)O under solvothermal conditions, which was characterized by infrared spectroscopy, single-crystal X-ray diffraction, powder X-ray diffraction, and thermogravimetric analyses. Single-crystal X-ray diffraction analysis reveals that 1 features a three-dimensional framework, which is built from interesting tetrahedral cages. The thermal stability of the complex has also been investigated. (C) 2016 Elsevier B.V. All rights reserved.

Abstract ：
A unique Rh/TiO2 solid acid catalyst modified with H2SO4 was synthesized and evaluated in the esterification reaction of propylene glycol methyl ether and decomposition of methyl orange (MO) in aqueous phase under halogen lamp irradiation. For this purpose, rhodium (Rh) nanoparticles were loaded on SO42-/TiO2 via the photo-deposition method. It was found that SO42-/Rh-TiO2 exhibited stronger catalytic activity than SO42-/TiO2. The new catalysts were characterized by X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET), Transmission electron microscopy (TEM) and high-resolution (HRTEM), X-ray photoelectron spectroscopy (XPS) and Fourier Transform infrared spectroscopy (FTIR). Results from XRD and BET show that SO42-/Rh-TiO2 has higher specific surface area and smaller pore size than SO42-/TiO2. The distribution of loaded Rh was found to be uniform with a particle size of 2-4 nm. Data from XPS reveal that Rh primarily exists as Rh-0 and Rh3+ in Rh-TiO2 and SO42-/Rh-TiO2. These valence forms of Rh likely contribute to the enhanced catalytic activity. Furthermore, FT-IR spectra of the catalysts show an abundance of surface hydroxyl groups, which help the formation of hydroxyl radicals and the enhancement of surface acid density. The results show that more acid sites are formed on the sulfated Rh-TiO2, and these acidic sites are largely responsible for improving the catalytic performance. This superior SO42-/Rh-TiO2 catalyst has potential applications in reactions requiring efficient acid catalysts, including esterification reactions and waste water treatment.

Abstract ：
TiO2 has been widely used as a key catalyst in photocatalytic reactions; it also shows good catalytic activity for esterification reactions. Different sulfated M-TiO2 nanoparticles (M = Ag, Au, Rh, and Pt) were prepared by photodeposition and ultrasonic methods. The results show that the noble metal nanoparticles, which were loaded onto a TiO2 surface, slightly affected the crystal phase and particle size of TiO2. Among all the catalysts, SO42-/Au-TiO2 exhibited the best catalytic activity in the esterification reaction for the synthesis of citric acid n-butyl acetate and in the decomposition of methyl orange, as confirmed by a high conversion rate of up to 98.2% and 100% degradation rate, respectively. This can be attributed to an increase in the Lewis acidity of the catalyst and increased separation efficiency of electron-hole pairs. This superior catalyst has great potential applications in esterification reactions and wastewater treatments.

Abstract ：
Solvothermal reaction of Pb(NO3)(2)center dot 6H(2)O with rigid linear ligand terephthalic acid (H(2)pta) in N,N-dimethylformamide (DMF) produced a new three-dimensional (3D) lead(II) coordination polymer [Pb-2(pta)(1.5)(mu(4)-OH)(DMF)](n) 1, and its structure was characterized by single-crystal X-ray diffraction analyses. In polymer 1, the mu 4-OH bridges the nearby lead(II) ions into an infinite one-dimensional (1D) chain, and then the organic ligand pta(2-) joins the neighbored chains into a 3D structure by two similar connection modes in different configurations. The solid-state photoluminescent studies revealed that 1 exhibits a strong greenish emission mainly originating from ligand-to-metal charge transfer between the delocalized pi bonds of the aromatic carboxylate ligand pta(2-) and the p orbitals of the Pb2+ centers.

Abstract ：
Porous cocoanut activated carbon was modified using tree chemical methods: tetraethylenepentamine (TEPA) modified directly (AC), firstly oxidized by HNO3solution (10%) for 4 h at 353 K then TEPA modified (HNO3+TEPA) and firstly alkalified by KOH solution (5 mol/L) for 4 h at 353 K then TEPA modified (KOH+TEPA). The results show that KOH reduction on AC improved the effect of the modification, HNO3oxidation on AC has no significant effect on modification. The CO2adsorption capacity of OH-TEPA-AC measured using a thermogravimetric analyzer (TGA) in simulated flue gas conditions (10vol% CO2, 90vol% N2) was about 1.182 mmol/g at 303 K, the dynamic adsorption capacity was between 1.192-1.215 and 0.970-1.152 mmol/g with or without the presence of water during ten cycles of adsorption/desorption. Dynamics analysis shows that the average isosteric heat of adsorption was about -52 kJ/mol, so OH-TEPA-AC was likely to be satisfactory in practical applications of capturing CO2. ©, 2015, Journal of Functional Materials.
