摘要
采用氯化钠和氢氧化钠联合一次性沉淀锰、铁、钛等干扰元素,铝离子与EDTA络合后,用硫酸铜滴定氟盐取代释放的与铝络合的EDTA,测定铝锰合金中之铝.
NaCl and NaOH are used in combination to precipitate the interference elements such as manganese,iron and titanium.After the aluminum ion and EDTA are complexed,sodium fluoride substitutes the aluminum-complexed,released EDTA by titrating with cupric sulfate,thus the aluminumcontent in Al-Mn alloy was determined.
