time irrespective of the surface type. Thus, it can be concluded
from the above experiment that formulation A develops excellent
results on aluminium foil immersed in water for up to
30 days. It may also be concluded from the above experiment
that SPR based on basic fuchsin and crystal violet can be a
good substitute to conventional SPR because of their
fluorescent contrasting and non-toxic properties. Results are
presented in Table 3 and Graph 1.
