ISO 9964 Determination of Sodium and Potassium in Water by Flame Emission
The ISO 9964 method is a standardized process used to determine the concentration levels of sodium (Na+) and potassium (K+) ions in water samples. This technique employs flame emission spectroscopy, which allows for precise quantification of these elements by measuring their characteristic emissions at specific wavelengths when excited by heat.
This method is particularly advantageous in sectors such as environmental monitoring, drinking water quality control, and wastewater treatment where accurate measurement of sodium and potassium ions is crucial. Sodium and potassium are essential electrolytes that play vital roles in various biological processes; thus, their presence or absence can indicate the overall purity of a water source.
The method involves several steps including sample preparation, which requires diluting the water sample to ensure it does not exceed the detection limits of the instrument. The diluted samples are then introduced into a flame, where they vaporize and excite the sodium and potassium atoms present. These excited atoms emit light at wavelengths characteristic of their atomic structure.
The emitted light is collected by a spectrometer, which separates the wavelengths to identify the specific emissions corresponding to sodium and potassium. The intensity of these emissions is directly proportional to the concentration of the respective ions in the sample. This allows for quantitative analysis and accurate determination of the ion concentrations in parts per million (ppm).
The ISO 9964 method ensures high accuracy and precision, making it a reliable tool for compliance with international standards such as ISO 3508-1:2017 "Water quality—Determination of sodium and potassium by flame emission spectroscopy" and ASTM D1129. The method’s simplicity and reliability make it suitable for both routine testing in laboratories and field applications.
By adhering strictly to the ISO 9964 protocol, we ensure that all measurements are consistent with internationally recognized standards. This consistency is crucial for maintaining quality control in critical industries such as pharmaceuticals, food processing, and water supply.
