可滴定的

In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.

在化合物2中，我们引进了硫原子在冠状醚中，则应对电子密度较低之金属有较好的结合能力，实验结果显示了此分子对铜离子有相当好的选择性和结合能力，萤光增加可达60倍；同时由红外光吸收光谱和核磁共振光谱滴定实验可确知，香豆素衍生物上的两个羰基对金属离子的选择性及结合上扮演相当重要的角色。

The dust was first mixed with NaBH4 powder to adjust the H/Cl ratio. Then, the sample was roasted at low temperature to promote the efficiency of dehalogenation/hydrogenation reaction. By way of Cl- titration, it was found that the roasting temperature (300℃~500℃), roasting time (5 to 25 minutes) and H/Cl ratio (6.0 to 20.0) would change the dissolution of Cl- from 0.0% to 17.5%. After caustic roasting and leaching of the dust, the zinc (17.4 g/l) and lead (1.6 g/l) recovery ratio were found to be 82.7% and 61.8% respectively.

利用NaBH4在低温可促进氯化冶金反应的进行，经由氯离子浓度滴定，发现随著焙烧时间、温度及H/Cl比值之调整，氯离子之溶出量变化亦相对改变，此结果说明在使用NaBH4调配H/Cl比值由6.0~20.0的变化下，烟尘中的氯成分在低温(300℃~500℃)焙烧5~20分钟，可与金属氧化物发生氯化反应，氯离子溶出量显示有0~17.5%不等之变化量。

A modified method was suggested to facilitate the extraction of alkaloidal salts as such from tablets by means of water,aqueous alcohol or other strong polar solvents.

可能代替药典中若干药物的法定含量测定方法，但须注意杂质影响。3。用水或醇自片剂中半微量法滤出有效成分，直接滴定，方法简便，可得满意结果。
