In this research, we address investigation and finding parameters of the two proposed model cascades for separation of multi-component mixtures (Matched-X and Pseudo binary type 1 cascades) in the context of Te-123 isotope separation and comparison of their performance in the condition of changing parameters k, k_1 and k_2. The results show that for a cascade with 10 stages and feed stage 5 and feed flow rate 100 gr/s, the minimum total inter stage flow of the matched-X cascade occurs in the condition k=7, k_1=1 and k_2=3, with the amount of 1881.133 gr/s. In this case, the concentration of Te-123 in the product stream of the cascade is equal to 0.0349 while the maximum product concentration of Te-123 occurs at k=1, k_1=1 and k_2=2 with the amount of 0.0389. In this cascade the total inter stage flow is equal to 2159.914 gr/s. Also, Results represent that in the Pseudo binary type 1 cascade, the minimum total inter stage flow and maximum product concentration of Te-123, occur simultaneously in the condition k=1, k_1=1 and k_2=2 with the amounts of 2159.914 and 0.0389 respectively.
