Determination of ethoxyquin content by non aqueous titration with perchloric acid was carried out in mixed solvent of glacial acetic acid (50mL) and acetic anhydride (1mL) with crystal violet as indicator .
研究了用高氯酸标准溶液对乙氧基喹含量的非水滴定 ,具体方法为 :精确称乙氧基喹0 2 g ,加 5 0mL冰乙酸、1mL乙酸酐、加 2滴结晶紫指示剂 ,用高氯酸标准溶液滴定至溶液由蓝紫色变为绿色。
Objective:The effect of the linseeds,VE and ethoxyquinoline in feed on the productive performance of the Hailanhong layers and ω-3 PUFA deposition in the yolk of laying eggs was studied.
目的:研究日粮中添加亚麻籽、VE、乙氧基喹啉对海蓝红蛋鸡生产性能及蛋黄中ω-3PUFA富集效果的影响。
