Kinetics Study of Excitation Process on Determination of Unsure by Emission Spectrographic Method

The research aim was to search the rate of reaction equation occurred in the excitation process during the determination of boron and cadmium impurities in U3O8 by emission spectrographic method. It was intended to obtain additional information that could be used to improve the analysis method using emission spectrographic, especially on the excitation process. From the intensity relationship with the carrier concentration, the best carrier concentration obtained was 5%. The relationship between boron and cadmium contained obtained during the excitation being varied with time is used to count the concentration so that a relationship between the concentration and time was obtained. By differential method, the relationship between the rate and concentration was obtained that these reactions followed first orde. This first orde could evaluated with integral method. The rate of reaction equations obtained for boron and cadmium respectively were -rB = - dCB/dt = 0.066 CA1 mg/g.s and -rCd = - dCCd /dt = 0.068 CA1 mg/g.s .(author)
