The determination of 2-mercapto-1-methyl-imidazole (MMI) in 5.0 M lithium perchlorate suporting electrolyte has been investigated by the differential pulse polarography. The optimum condition of MMI analysis was as follows; -0.9 volts initial potential, 0.08 mV pulse height, 2 mV/sec scan rate, and medium mercury drop size. Standard calibration curve showed a good linearlity in the range of 1.0 M and the detection limit has been (2.2 M. This method was applicated for the determination of MMI in antithyroid drug without interference of additives. |
