- W2376729029 abstract "The aluminum manganese alloy sample is melted in sodium peroxide.When the sample completely decomposed,ethanol is added and boiled to reduce the high valence of manganese.Thus the interference of high valence manganese is eliminated.Because Al is amphoteric,the Fe,Mn and Ti in the sample can generate alkaline oxide precipitation and are separated with Al by filtration.A portion of filtrate is acidified and EDTA is added to generates coordination complex with Al.Zinc acetate standard solution is used to backtitrated the excess EDTA.KF is added and quantitative coordinated with Al.Zinc acetate standard solution is then used to titrate the substituted EDTA and get the content of aluminum.The proposed method has only one separation process.It is simple,rapid and accurate,and can be applied to the determination of the aluminum which amount is 10%~50% in the alloy of aluminum and manganese.The relative standard deviation(RSD,n= 5) is less than 0.5% and the recovery is 98.5%~101%." @default.
