Specifies a method for the analysis of water samples for the following elements: aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, caesium, chromium, cobalt, copper, gallium, germanium, gold, lead, lithium, manganese, mercury, molybdenum, nickel, palladium, platinum, rhodium, rubidium, selenium, silver, strontium, tellurium, thorium, thallium, tin, titanium, uranium, vanadium, and zinc.

Scope

This Standard specifies a method for the analysis of water samples for the following elements: aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, caesium, chromium, cobalt, copper, gallium, germanium, gold, lead, lithium, manganese, mercury, molybdenum, nickel, palladium, platinum, rhodium, rubidium, selenium, silver, strontium, tellurium, thorium, thallium, tin, titanium, uranium, vanadium, and zinc.
NOTES:
1 Other elements may be determined by this method if adequate performance is demonstrated. Depending on the sample pre-treatment, the method is applicable to the determination of dissolved and total recoverable elements. This Standard should be read in conjunction with AS 4873.1.
2 This Standard may be used as a guide for the determination of elements in other matrices provided adequate performance is demonstrated.
3 This method is suitable for the determination of elements in aqueous solutions where suspended or particulate material is <0.1% (w/v).
4 Water samples containing sediment or suspended particulate matter >0.1% (w/v) should be digested using methods for sediment (e.g. aqua regia digestion) before analysis.
5 This method is applicable for the determination of dissolved elements and total recoverable (acid extractable) elements. It is not suitable for the determination of ā€˜total elementsā€™ concentrations unless appropriate procedures have been followed to ensure the dissolution of any silicates present.
6 This method is suitable for non-saline water. For the analysis of saline water, samples should be diluted to reduce dissolved solids to (0.3%. Several elements are prone to interference from polyatomic ions originating from the matrix and appropriate techniques should be used for the determination of such elements.
7 Before any samples are taken, it should be established whether dissolved element concentrations or total recoverable element concentrations, or both, are required.
