摘要：
依据2009—2015年间武汉市COD排放量、GDP、人口等基本数据,对武汉市COD排放的时序特征、人均COD排放量、万元GDP COD排放量进行了分析并建立了武汉市COD排放的环境学习曲线。结果表明武汉市COD排放量、人均COD排放量、万元GDP COD排放量总体呈现下降的趋势,COD排放的环境学习曲线方程为y=0.026x-1.276 9,并得出在"十三五"末武汉市的COD排放量约为13.395万吨。武汉市经济质量整体偏好,但COD减排的压力依然较大。

摘要：
环境工程微生物学是环境类专业的学科基础课,该课程对学生的知识架构以及应用技能的培养起到了重要支撑作用。为了实现该课程定位目标,达到课程的学习预期,我们将成果导向教育理念(Outcomes-based education,OBE)引入到环境工程微生物学课程教学改革实践中,提出在环境工程微生物学课程教学中实施逆向设计、正向实施的原则,即根据课程定位制定环境工程微生物学的预期学习产出,在预期学习产出的基础上优化教学过程,如对教学内容进行取舍,增强环境工程微生物学与其他课程的协调性,在教学实施中强化学生的主体地位,通过教学方法的改革促成预期学习产出,构建合理的学习评价体系。尽管将OBE理念引入到教学实施中取得了一些成效,但该体系的建设还有待于进一步完善。

摘要：
A novel Sc(iii) ion-imprinted polymers (Sc-IIP) sorbent was prepared by using Sc(iii) ion-8-hydroxyquinoline complex as the template molecule and methacrylic acid, ethylene glycol dimethacrylate (EGDMA) as the functional monomer and cross-linker, respectively. In the present work, a new method using a microcolumn packed with Sc-IIPs as a solid-phase extraction adsorbent was developed for the selective separation and preconcentration of trace amounts of scandium(iii) prior to the determination by inductively coupled plasma mass spectrometry. Various factors influencing the separation and preconcentration of trace scandium, such as pH, sample flow rate and breakthrough volume, elution concentration and volume were investigated in detail. Scandium can be quantitatively retained on the IIPs sorbent at pH 4.0-6.5 from sample volume up to 300 mL and then eluted efficiently with 5 mL 3% HNO3 solution, therefore an enrichment factor of 60 was accomplished. The maximum adsorption capacity of the ion-imprinted and non-imprinted sorbent was 12.8 mg g -1 and 3.5 mg g-1, respectively. Under optimal conditions, the detection limit for scandium was 0.013 ng L-1 in water, 0.46 ng g-1 in geological sample, and the relative standard deviation was 3.2% (n = 11) at the 0.5 μg L-1. The recoveries of Sc in the spiked environmental water samples ranged from 98.0% to 103% with 100 mL of water sample. The proposed method was validated using certified reference materials and applied to the determination of trace scandium in geological samples and environmental water samples with satisfactory results. © 2013 The Royal Society of Chemistry.

摘要：
A novel method that uses chemically modified persimmon powder for solid extraction of Au prior to the determination by inductively coupled plasma-mass spectrometry (ICP-MS) was investigated. Experimental conditions such as acid concentration, sample flow rate and volume, eluent conditions and interfering ions were carefully examined. Gold can be quantitatively adsorbed on the new sorbent from solution of 3% (v/v) aqua regia, and then the trace gold adsorbed on the microcolumn can be effectively eluted with a mixture of 2.0% thiourea and 0.12 mol L-1 HCl. The transition- and heavy-metal ions did not interfere with either the separation/preconcentration or the determination. The maximum adsorption capacity of the sorbent was 25.3 mg g-1. Under optimal conditions, the detection limit for gold was 1.32 ng L-1 in the geological sample, and the relative standard deviation was 0.83% (n = 11) at 1.0 μg L-1. The proposed method was validated by analyzing three certified reference materials and applied to the preconcentration and determination of trace gold in geological samples with satisfactory results. © 2013 The Royal Society of Chemistry.

摘要：
A chicken eggshell membrane (ESM) was used as a solid-phase extraction adsorbent for the separation and preconcentration in combination with inductively coupled plasma-mass spectrometry (ICP-MS) for the determination of trace gold in geological samples. Gold (Au) was quantitatively separated and preconcentratcd in 1.2 mol L-1 HC1 at a sample flow rate of 2.0 mL min.1 using the ESM microcolumn system. The gold adsorbed on the microcolumn was effectively eluted with a mixture of 1% thiourea and 0.12 mol L1 HCL The effects of acid concentration, sample flow rate and volume, eluent conditions and interfering ions were carefully investigated. The transition- and heavy-metal ions did not interfere with either the separation/preconcentration or the determination. The limit of detection of the method for Au was 0.92 ng L-1. The method was validated using certified reference materials and applied to the determination of trace Au in geological samples with satisfactory results.

摘要：
The air-steam catalytic gasification of rice husk for hydrogen-rich gas production was experimentally investigated in a combined fixed bed reactor with the newly developed nano-NiO/γ-Al2O3 catalyst. A series of experiments have been performed to explore the effects of catalyst presence, catalytic reactor temperature, the equivalence ratio (ER), and steam to biomass ratio (S/B) on the composition and yield of gasification gases. The experiments demonstrated that the developed nano-NiO/γ-Al2O3 catalyst had a high activity of cracking tar and hydrocarbons, upgrading the gas quality, as well as yielding a high hydrogen production. Catalytic temperature was crucial for the overall gasification process, a higher temperature contributed to more hydrogen production and gas yield. Varying ER demonstrated complex effects on rice husk gasification and an optimal value of 0.22 was found in the present study. Compared with biomass catalytic gasification under air only, the introduction of steam improved the gas quality and yield. The steam/biomass ratio of 1.33 was found as the optimum operating condition in the air-steam catalytic gasification. © 2010 Professor T. Nejat Veziroglu.

摘要：
The determination of chlorpyrifos at low ngL-1 levels in wastewater requires highly selective and sensitive analytical procedures. The removal of matrix components during sample preparation results in significant benefits towards reducing the matrix effects during GC analysis. Therefore this work describes a simple method to enrich and clean up chlorpyrifos from sewage water using molecularly imprinted solid phase extraction (MISPE). Final analysis was performed by gas chromatography. The performance of this method has been evaluated in water samples in terms of recovery, precision, and method quantification limit. Recovery for chlorpyrifos ranged between 99 and 105% with RSD values below 7.9%. The performance of the method was further emphasized by the study of different water samples. In these samples, chlorpyrifos were detected in concentration above method quantification limits ranging from 50 to 3000 ngL-1. © (2010) Trans Tech Publications, Switzerland.
