4. Conclusion
A simple method was proposed for the speciation of Sb(III) and
Sb(V) by adsorptive linear sweep voltammetry using H-point standard
addition method. This study demonstrated that HPSAM can be
useful in speciation analysis, even with highly overlapped voltammograms.
It was also shown that high selectivity was added to high
sensitivity of adsorptive voltammetry methods by using HPSAM.
