![]() Through reasonable optimization of parameters such as a sodium-potassium analysis spectral line in an ICP emission spectrum, RF power and atomizer flow, and an observation mode and observation height, analysis steps are greatly simplified and analysis precision and accuracy are improved. ![]() The method can realize direct detection of sodium and potassium in low sodium salt, is free of drugs such as acetic acid and turpentine with excitant smells used in the QB2019-2005 standard and other reagents and prevents subtraction method-based Na measurement error caused by impurities. The method comprises dissolving low sodium salt in a proper amount of dilute HNO3, adding water into the solution for volume metering, detecting sodium and potassium content at specific wavelength by ICP subjected to specific parameter adjustment and carrying out conversion from the sodium and potassium content into NaCl and KCl content. The invention belongs to the field of analytical chemistry and relates to a method for detection analysis of sodium and potassium in low sodium salt.
