1. Simplicity: ]5% of Sn can be determined by
taking 0.2 g of sample or even an aliquot there
from. This makes the separation simpler and
easier.
2. Selectivity: a single clear-cut precipitation in
combination with masking suffices to eliminate
most of the interferences and render the determination
specific for Sn in most cases.
3. Versatility: provision is made for eliminating
interferences in special cases, such as correction
for Mo and V. This makes it also applicable
to the analysis of Ti alloys.
4. Flexibility: it is flexible in the technique of
sample decomposition and simplifications are
possible in the absence of certain interferents.
Owing to these features the proposed method
will find many industrial applications. The results
for analysis of some simulated and industrial samples
are shown in Tables 4 and 5 respectively.
