產品詳情

詳細信息(中文)：
銅鐵試劑是一種重要的分析試劑，為N-亞硝基羥胺的銨鹽，俗稱銅鐵靈。通常情況下為白色或淡黃色光亮的鱗片狀結晶，有甜味，久置因慢慢分解而顏色變暗，但實際上還可以在分析上使用。它易溶于水、苯、醇、醚。試劑受熱Chemicalbook分解生成硝基苯。在光和空氣中不穩(wěn)定，需要保存在棕色磨口試劑瓶中，通常瓶內放置少量用紙或布包好的碳酸銨作為防腐劑，放在密封避光陰涼處。可用作銅、鐵、錫、鈦、釩、鉻等元素的沉淀劑和溶劑萃取劑，測定稀土作掩蔽劑

詳細信息(英文)：
Cu-fe reagent is an important analytical reagent, which is the ammonium salt of N-nitrosamine, commonly known as Cu-Fe reagent. Usually white or yellowish shiny scaly crystals, sweet and dark with gradual decomposition, but can actually be used for analysis. It is soluble in water, benzene, alcohol and ether. The reagent is heated to break down Chemicalbook to form nitrobenzene. Unstable in light and air, it needs to be stored in a brown ground reagent bottle, usually a small amount of paper or cloth wrapped ammonium carbonate in the bottle as a preservative, put in a sealed place away from light and shade. It can be used as precipitator and solvent extraction agent for copper, iron, tin, titanium, vanadium, chromium and other elements to determine the rare earth as a masking agent
