title: [Determination of Rh in removal solution of the catalyst from HNBR by FAAS].
abstract: The content of Rhodium in extraction solution of the catalyst from HNBR was determined by FAAS. The results showed that this method was simple, rapid, accurate and convenient. Furthermore, this method was used as a means to investigate the optimum process conditions for removing catalyst from HNBR by ligation-extraction technology. When sulfocarbmide was used as a ligation agent and 88% formic acid as an extraction agent, the removal rate of Rh was greater than 98% under the condition of 100 degrees C and two hours of reaction time.
