酚酞

6 To the bottles resered as blanks, melt the ice, add 6 to 8 drops of the phenolphthalein indicator solution to the bottles and titrate to a pink end point.

10.1.6 保留空白样品的瓶子，直接加入融化的冰，在瓶子里加入6到8滴的酚酞指示剂溶液来标示滴定终点。

8 Add 6 to 8 drops of the phenolphthalein indicator to each bottle and titrate with 0.1 N H2SO 4 just to the disappearance of the pink color.

10.1.8 在每个瓶子中加入6到8滴酚酞溶液，再逐步加入0.1mol/lH2SO 4至粉红色消失

Through chloromethylated, aminate and hydrolytic reaction, OH-form quaternized PES-C membranes were synthesized.

通过氯甲基化、胺化、水解等反应，制得了OH型季胺化酚酞型聚醚砜阴离子交换膜。

At the same time, using bromocresol green - methyl red indicator and phenolphthalein indicator control instructions with the free acid end of the titration end sensitive and accurate.

同时，采用溴甲酚绿-甲基红指示剂与酚酞指示剂配合指示调控游离酸的终点，使滴定终点灵敏、结果准确。

A mixed indicator composed of bromocresol green, methyl red and phenalphthalein was used as indicator in titration of boron after the inteterience of cobalt was masked by EDTA.

采用甘露醇强化硼酸滴定硼时，以EDTA为掩蔽剂，可消除二价钴对硼分析的干扰；改用溴甲酚绿-甲基红-酚酞三元混合指示剂作为测定硼的指示剂，使滴定终点灵敏，准确。

Optimized technical conditions results from experimental analysis is as follows: Temperature is 60 ℃, limed phenothalin alkalinity is 0.9, CO_2 Charging time is 30 min.

通过单因素试验分析结果，确定正交试验方案，经实验分析、讨论、确定最佳工艺条件为：温度为60℃，加灰酚酞碱度0.9，饱充时间30min。

By the use of standard substance, a standard spectrum library was established for 10 drugs, metformin, ephedrine, pseudoephedrine, caffeine, phenformin, fenfluramine, indapamide, phenolphthalein, fluoxetine and sibutramine. The identification for illegally added drugs was performed by comparing the accordance of retention time and the three-grade mass spectrum with the standard spectrum library.

利用标准物质建立10种药物（二甲双胍、麻黄碱、伪麻黄碱、咖啡因、苯乙双胍、芬氟拉明、吲达帕胺、酚酞、氟西汀、西布曲明）标准谱库，通过与标准谱库保留时间和三级质谱图的比较对非法添加的药物进行定性鉴别。
