Hypothesis
A new method using hydrazine hydrate can accurately determine elemental sulphur in rubber samples.
Conclusion
The study developed a sensitive method for determining sulphur in rubber that shows less interference than previous methods.
Supporting Evidence
- The method showed reproducibility with a standard deviation of 0.0005.
- The results were accurate when compared to the Proske method.
- The method requires less time and has fewer interferences than previously reported methods.
Takeaway
This study found a new way to measure sulphur in rubber that is quick and doesn't get confused by other chemicals.
Methodology
The method involved using d.c. polarography, cyclic voltammetry, and millicoulometry with hydrazine hydrate as a solvent.
Limitations
The method may have limitations in the presence of interfering substances that were not fully explored.
