一般說明
硝酸钾是一种常用作氮肥的水溶性无机盐。 它在牙膏中可作为牙齿过敏的脱敏剂。 向生长培养基中添加KNO3已显示出可促进盐胁迫的甜瓜植物的生长。
應用
硝酸钾可被用于通过使用N-溴代琥珀酰亚胺对异喹啉进行溴化来合成5-溴-8-硝基异喹啉。

Direct current (DC) stimulation can be used to influence the orientation and migratory behavior of cells and results in cellular electrotaxis. Experimental work on such phenomena commonly relies on electrochemical dissolution of silver:silver-chloride (Ag:AgCl) electrodes to provide the stimulation via
