球墨铸铁及铜合金中稀土总量的分析已经有了高速分析方法。高合金钢中由于含有多量铬、镍、钼、铜、钒、钛、钨、钴、锰、铝及铌、锆等,需用氟化物沉淀使稀土分离后进行测定,不能在几分钟内完成操作。由于生产上的迫切须要,我们进行了高合金钢中稀土总量高速分析方法的研究。铜合金中稀土的高速分析是用铜试剂分离干扰元素的。在微酸性溶液中能与铜试剂生成沉淀的元素有铁、铬、镍、钴、铜、锰、钨、钒、铌、钼、铅、铋、锡、
Analysis of the total rare earths in ductile iron and copper alloys already has a high-speed analytical method. Due to the large amount of chromium, nickel, molybdenum, copper, vanadium, titanium, tungsten, cobalt, manganese, aluminum, niobium and zirconium in high-alloy steel, the rare earth should be separated after being precipitated by fluoride and can not be finished within several minutes operating. Due to the urgent need of production, we conducted a high-speed analysis of high-alloy steel rare earth total analysis method. Copper alloy rare earth high-speed analysis is the use of copper reagents to interfere with the separation of elements. Elements that can be precipitated with copper reagents in slightly acidic solutions include iron, chromium, nickel, cobalt, copper, manganese, tungsten, vanadium, niobium, molybdenum, lead, bismuth, tin,
