Applications of Scientific Inquiry Teaching in Instrumental Analysis Courses

为了提高《仪器分析》课程教学质量，该研究在环境工程与制药工程专业的《仪器分析》课程中分别采用了两种教学模式：一种是“填鸭式”的教学，老师讲学生听；另一种是探究式，引导学生对一些知识点进行探索．后者这种教学活动过程包括：设问质疑，做出猜测或假设、交流，得出初步结论．通过一学期的实践与比较，发现探究式的教学效果比传统讲授的教学效果要优越．In order to improve the learning and teaching quality of instrumental analysis courses, two different teaching styles were carried out in two classes of environmental engineering specialty （counterparts） and pharmacy engineering specialty, respectively. One style is to cramming method of teaching： students passively accept their teachers＇ lecture and take notes; another format is a scientific inquiry teaching： to guide the students to explore knowledge point. This teaching style includes the following processes： subse- quently, to assign homework to students before class, to design problem environments, to pilot students to inquire problem on their own, and to propose their guess or hypothesis, to test their hypothesis and conduct deductive reasoning, to motivate students to find law and finally make conclusion in classroom. The investi- gations found that the scientific inquiry teaching was superior to the traditional one through a semester exper- iment.广西高等教育教学改革工程项目(2014GA129);广西民族大学2103年度高等教育教学改革工程项目(2012XJGY23

Preparation and Electrochemical Properties of Phenobarbital

了改善分子印迹传感器的灵敏度,在四丁基高氯酸铵的支持电解质溶液中,以甲基丙烯酸为功能单体,马来松香丙烯酸乙二醇酯为交联剂在纳米氧化铜修饰过的玻碳电极上电聚合了一种苯巴比妥(PB)识别性能的分子印迹传感膜.采用循环伏安(CV)法、差分脉冲伏安(DPV)法及交流阻抗(EIS)法对这种纳米氧化铜修饰过的印迹及非印迹电极的电化学性能进行了研究,结果显示纳米氧化铜修饰过的印迹及非印迹电极的电化学性能完全不同.X射线衍射(XRD)证实纳米粒子为氧化铜.采用扫描电镜(SEM)对纳米氧化铜修饰过的印迹传感器的形貌进行分析,发现纳米氧化铜分散在电极表面,改善了修饰印迹传感器的识别点.差分脉冲伏安法(DPV)表明苯巴比妥的浓度在1.0×10-8-1.8×10-4mol·L-1范围内呈现良好的线性关系(线性相关系数R=0.9994);检出限2.3×10-9mol·L-1(信噪比(S/N)=3).研究结果表明纳米氧化铜修饰过的印迹传感器具有较高灵敏度及选择性.此印迹传感器能用于实际样品中苯巴比妥的检测,加标回收率在95.0%-102.5%.Abstract: To improve the sensitivity of molecular imprinted electrochemical sensors, a molecularly imprinted polymer (MIP) film for the determination of phenobarbital (PB) was electropolymerized on a CuO nanoparticlemodified glassy carbon electrode. Methacrylic acid was used as the functional monomer and ethylene glycol maleic rosinate acrylate as a cross-linking agent in the presence of supporting electrolyte (tetrabutylammonium perchlorate). The electrochemical properties of CuO nanoparticle-modified molecularly imprinted and non-imprinted polymer (NIP) sensors were investigated by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS). The results showed that the electrochemical properties of the CuO nanoparticle-modified MIP sensor were completely different from those of NIP sensors. X-ray diffraction confirmed that the nanoparticles were CuO. The morphology of the CuO nanoparticle-modified MIP sensor was examined under a scanning electron microscope. The CuO nanoparticles were uniformly distributed on the surface of the modified glassy carbon electrode, which improved the recognition sites of the modified MIP sensor. The response value of the DPV peak current showed linear dependence on the PB concentration in the range 1.0×10-8 to 1.8×10-4 mol∙L-1 (linear regression coefficient =0.9994) with a detection limit (S/N=3) of 2.3×10-9 mol∙L-1. The results indicated that the CuO nanoparticle-modified MIP sensor is one of the most sensitive and selective sensors for PB determination. The prepared sensor was successfully applied for the determination of PB in practical samples and the recovery ranged from 95.0% to 102.5%.广西教育厅科研项目(2013YB068);国家自然科学基金(21365004);广西自然科学重点基金(2013GXNSFDA019006);广西高等学校高水平创新团队及卓越学者资助计划(桂教人[2014]7号);广西研究生教育创新计划项目(gxun-chx2014120)资
