A new method for determination of potassium in honey samples of different colors was developed as an alternative method for determination of this metal. Analysis of genuine honeys attested by the qualities and quantities tests officially adopted in Brazil, showed that the concentration of potassium ranged from 181 to 315 mg/kg for light honeys, from 393 to 570 mg/kg for medium honeys and from 791 to 915 mg/kg for dark honeys. Recoveries making use of spikes of potassium added to the honey samples and to the deionized distilled water showed results close by hundred percent at pH <= 2,0 under temperature bellow 20°C.
