| Abstract: | The BCO spectrophotometric method applied to the detection of copper content in aluminium alloys containing nickel has been improved by adding NH 3-NH 4Cl as buffer solution. The results show that the absorbances are very stable and repeatable. The improved method is not only easy and practical, but also especially suitable for the ladle analysis. |
