Determination of phosphorus in rubber by nitric acid digestion

Norhayati M., . and Jakathesa D., . and Mohd. Ali M. D., . Determination of phosphorus in rubber by nitric acid digestion. pp. 219-222. ISSN 0127-7065

Currently a separate digest is required for the analysis of phosphorous (P) in rubber. This involves extra cost and time. Determination of P using the same digest as for all the other elements was tested and compared to the normal procedure. The concentration of P obtained was comparable with coefficient of variation of less than 10. The regression equation obtained was Y 0.996x - 9.28 with r2 0.924 significant at 0.001. The standard error was 0.014. Based on the results obtained it is thus feasible to analyse P and all the other elements together in a single digestion procedure.
