Abstract
It has been shown that Sulfarsazen and -5-nitrophenyl)-3-ethyl-5-(2-be
nzoxazolyl)formazan (Formazan VIII) can be used for the photometric de
termination of lead and give identical results at a specified signific
ance level. The detection Limits attained with the use of Sulfarsazen
and Formazan VIII are 0.2 mu g/mL and 0.16 ng/mL, respectively, and th
e latter reagent provides a better precision of determination.
