| Abstract: | Microwave digestion technique was used in decomposition of polyisoprene rubber and the contents of Titanuium was determined of by ICP . The digestion system, optimizing spectral analysis, transmit power, nebulizer flow, plasma gas flow rate, injection volume and other factors were studied,and the optimal experimental conditions were accomplished. The results show that , the ICP-OES mehtod for detect of titanium in polyisoprene rubber recovery rate between 95-105%. The methods has low detection limit and wide line arrange and is simple quick accurate.It is suitable for the determination of Ti content in polyisoprene. |
