     Abstract A simple, rapid, and sensitive malachite green-based spectrophotometric method for selective trace determination of an iodate is developed and presented for the first time. The reaction mixture was specifically involved in the liberation of iodine in the presence of an excess iodide in acidic condition following the instantaneous reaction between the liberated iodine and malachite green dye. The optimum condition was done with the buffer solution pH 5.2 in the presence of 40 mg L-1 potassium iodide and 1.5x10-5 M malachite green for 5 min incubation time. The iodate contents in some table salt samples were in the range of 26 to 45 mg kg-1, while those of drinking water, tap water, canal water, and seawater samples were not detectable (< 96 ng mL-1 of limits of detection, LOQ) with their satisfied method of recoveries between 93 % and 108 %. Results agreed with those obtained using ICP-OES for comparison.
