American Journal of Analytical Chemistry 2012年第2期3卷 106-112页

A comparison of voltammetric behavior of bisoprolol fumarate (BF) at edge and basal plane pyrolytic graphite electrodes (EPPGE/BPPGE) has been made with single wall carbon nanotube modified glassy carbon. The electrochemical properties are investigated exercising the cyclic voltammetry and square wave voltammetry (SWV). Enhanced peak current associated with bisoprolol fumarate oxidation at EPPGE is due to its better electron transfer property. Quantification of bisoprolol fumarate was carried out at pH 7.2 at both the pyrolytic graphite electrodes. Well-defined peak has been observed at ~ 792 and 954 mV at EPPGE and BPPGE respectively for bisoprolol fumarate oxidation. The detection limit is found to be 2.8 × 10–7 M and 7.3 × 10–7 M for EPPGE and BPPGE respectively. A comparison of common quantification parameters for bisoprolol at carbon nanotube modified glassy carbon electrode and bare BPPGE and EPPGE has been made and it is observed that carbon naotube modified glassy carbon exhibits sensitivity and detection limit close to that observed at bare basal plane pyrolytic graphite electrode. The method developed is applicable for determination of bisoprolol fumarate in pharmaceutical preparations and real samples.

anoop singh先生出席开幕式并发表主旨演讲,他表示,资本帐户的开放和货币可自由兑换,并非是人民币加入SDR的必要要求,这是第一次采取了这样的模式,相当于承认持续性的发展是至关重要的。他认为,人民币国际化仍旧处于初级阶段。在人民币市场中,系统性波动取决于市场预期,而市场预期近几年发生了变化。IMF将人民币入篮,是为了加速结构性改革,使经济重减少对于信贷的一来,并进一步推进消费升级、提振市场力量。因此,需要关注经济发展的方向。人民币国际化的基石,就是经济发展和新的增长模式逐步确立。

阿努普·辛格先生在论坛开幕式上,以中国资本账户对外开放所面临的问题为题发表演讲。他指出,鉴于人民币国际化可能会引起人民币离岸与在岸市场汇率波动,应当对中国的宏观金融风险进行防范;中国资本账户的进一步开放,需要稳健的资本市场和健康的金融机构来保障宏观经济的稳定运行;人民币加入SDR后需要中国央行与IMF成员国保持沟通,更加广泛地参与国际事务,强化人民币在SDR篮子中的地位。最后,他强调,人民币的对外开放会减少资本账户的波动性,有利于构建一个完善的资本市场。以下为演讲实录:
