| 1 | This standard (Part 45) prescribes following five methods for determination of sodium and potassium in water and wastewater: a) Flame emission photometric method using either a flame photometer or an atomic absorption spectrophotometer in the flame emission mode; b) Atomic absorption spectrometric method using an atomic absorption spectrophotometer in flame absorption mode (0.20 mg/l to 4.0 mg/l for potassium and 0.20 mg/l to 3.0 mg/l for sodium); and c) Gravimetric method for determination of sodium and colorimetric method for determination of potassium. d) Determination of potassium using Ion-selective electrode method; and e) Inductively coupled plasma spectroscopy. | |
