氨水

Aminobutyric acid in tea was extracted, isolated and determined. Water achieve a better effect than ethanol in extracting γ-aminobutyric acid, and γ-aminobutyric acid content was enhanced by 20%; 732 positive ion resin columns (2.5×50cm) was used to isolate, citric acid and ammonia water were used as elutes, based on pH linear gradient. Results indicated that γ-aminobutyric acid inelute could reach 39%; thin layer scanner could measure the content of γ-aminobutyric acid.

对茶叶中γ-氨基丁酸的提取、分离及检测方法进行了研究，分别采用水和乙醇作为提取溶剂，结果发现用水提取能达到更好的效果，γ-氨基丁酸含量提高20％；同时采用离子交换树脂对γ-氨基丁酸提取液进行分离，提取液上732阳离子树脂柱(2.5 ×50cm)，使用柠檬酸和氨水缓冲液进行pH线性梯度洗脱，洗脱液中γ-氨基丁酸最高浓度达39％；采用薄层扫描仪对γ-氨基丁酸的含量进行检测，研究并确定了检测的条件及参数。

Studies on the effect of eluting time,temperature and ultrasonic on elution rate are carried out and X-ray fluorescence are used in analysis.

针对硫酸溶液可以有效洗脱树脂上的氰化物和锌，但不能洗脱铜的工艺问题，选择氨水溶液对酸洗后201×7树脂上的铜进行解吸；试验研究了解吸过程的时间、温度以及超声波作用等条件对解吸率的影响，并进行了X射线荧光分析。

Technical grade propylene(92-93 percent,the balance being propane ) and anhydrous fertilizer grade ammonia are satisfactory.

技术级的丙烯（92－93％，平衡剂为丙烷）和无水化肥级氨水就能满足要求。

Despite NH3-H2O is consumed in chemical reaction,(NH4)2SO4 can be directly reclaimed for the chemical fertilizer or ammonia,and ammonia can be recycled as precipitating agent .

与传统的酸法制备铁黄颜料工艺不同的是，本研究用NH_3·H_2O代替NaOH作沉淀剂制晶种，在二步氧化中通过滴加氨水和硫酸亚铁溶液替代铁皮。

This paper introduces how the small fertilizer plant control diluted ammonia waste water by process flow of recovery liquid ammonia product by distillation technology, and also introduces its equipment selection, project investment and benefit analysis.
