Abstract
|
|
|
Aluminium and chromium in its base metal were determined by colorimetry of Bismark Brown R without using of any masking agents, Cu( I[), Fe (jjj), Zn(M and HfQV) were interfered with the determination of Al(M)and Cr(jj[) in the concentration range of 1,000 X 10-´ M but they were not interfered in 1,000 X10-´ M.
Tartrate and citrate ions had to be removed from the sample solation because of interfering.
