The control of traoe impurities in high purity rhodium used for thermocouples has ecome extremely important in recent years. To meet this need a direot optioal emission peotrographic method for determining 14 impurities in high purity rhodium sample has been tudied. The effect of the are ourrent, the eleotrode shapes, the ratios of buffers and the ontrolled atmosphere were studied. The volatilization profiles of all the impurities are shown n this paper.Based on these investigations, a prooedure has been established. The teohnique tilizes a do are operating at 10A and 20A with 1:1 Ar-O_2 atmosphere. The apparatus employed nd the operating conditions are listed. The line pairs used for the 14 impurities and the nalytical ranges are shown in Table l(in Chinese Text).Preparation of standard: All impurities re added to high purity rhodium solution, then ammonium chloride is added. The combined ixture s dried under infrared lamps. The salts are crushed to powder and reduoed in a hydrogen tmosphere.Sample preparation: a weighed sample, with a calculated mixture of ooncentrated ydrochlorio aoid and perhydrol, is sealed in a Pyrex tube, is heated to 140℃ until the sample s completely dissolved. The prooedure that follows are the same as that desoribed in the reparation of standards.The results indicate that 14 elements can be determined with an ccuracy within 30% of the precision limits. The effect of atmophere has also been discussed.
