IS 3025 : Part 53 : 2024 Methods of Sampling and Test (Physical and Chemical) for Water and Wastewater - Part 53 Iron

ICS 13.060.50

CHD 36

1 SCOPE

1.1 This standard (Part 53) prescribes following four methods for the determination of iron in water and wastewater:

a) 1,10 phenanthroline method (applicable in the range of 75 ìg/1 to 500 ìg/1 of iron);

b) Direct air-acetylene flame atomic absorption spectroscopy (applicable for 0.3 mg/l to 10 mg/l) method;

c) Extraction/air-acetylene flame atomic absorption spectroscopy method; and

d) Inductively coupled plasma spectroscopy method.

1.2 Depending upon the concentration range and interference levels, choice of the method is made.
