An inductively coupled plasma atomic emission spectrometry(ICP-AES) combined with a boron hydride vapour generation device was used for the determination of rhodium in waste catalyst. When the flow rate of sample and sodium borohydride solution was 2 mL/min, waste rate was 6 mL/min, the optimum conditions were as follows: 0.4 L/min of carrier rate, 1.0 mol/L of acidity of nitric acid for vapor generation and concentration of sodium borohydride 1.2(m/V). The study showed that a two-fold increase in the efficiency of rhodium was achieved as compared to nebulization. The detection limit was 6.9 μg/L, which is slight better than that of with nebulization. The linear range for rhodium was 20-1500 μg/L with a correlation coefficient of 0.9986. The mean recovery of sample analysis was 95.5%. Excellent agreement was found between the present method and FAAS.
