Abstract

The RRIM test method used in natural rubber nitrogen content analysis was modified for the determination of low levels of nitrogen in raw deproteinised natural rubber. The modified method gives good reproducibility and accuracy as indicated by elemental analysis. FTIR analysis through the measurement of the intensity ratio of N-H stretching to CH out-of-plane deformation band provides a rapid method for the quantification of low nitrogen content of purified natural rubber.
