This Standard specifies a method for the determination of residual acid soluble sulfur (SRAS) in acid sulfate soil after peroxide digestion (AS 4969.3) and the determination of peroxide sulfur (SP) (AS 4969.5). In order to perform this method, AS 4969.3 and AS 4969.5 shall have already been performed on the same test portion.

This Standard specifies a method for the determination of residual acid soluble sulfur (SRAS) in acid sulfate soil after peroxide digestion (AS 4969.3) and the determination of peroxide sulfur (SP) (AS 4969.5).In order to perform this method, AS 4969.3 and AS 4969.5 shall have already been performed on the same test portion.NOTES:1 This extraction procedure recovers the relatively insoluble iron and aluminium hydroxy sulfate compounds (e.g. jarosite, natrojarosite, basaluminite) which are not measured to any significant extent in SP.2 SRAS, unlike SNAS, (AS 4969.11) does not measure significant sulfur from organic matter as this is removed during rinsing of the soil residue. Some laboratories may prefer to perform SNAS analysis for operational reasons.3 This procedure would normally only be performed on a soil with a potassium chloride pH ( 4.5 (pHKCl, (AS 4969.2) or where jarosite/natrojarosite and similar minerals have been identified in the soil when it was sampled.
