This Standard specifies a method for the determination of peroxide pH (pHOX), titratable peroxide acidity (TPA) and excess acid neutralizing capacity (ANCE) in acid sulfate soil following digestion with 30% hydrogen peroxide.NOTES:1 The TPA measurement does not quantitatively recover retained acidity held in iron and aluminium hydroxy-sulfate minerals such as jarosite [KFe3(SO4)2(OH)6] and similar minerals. Methods to determine the retained acidity are given in AS 4969.6 and AS 4969.11.2 The suspension obtained from this method can be analysed subsequently to determine peroxide sulfur, calcium and magnesium (AS 4969.5) followed by the determination of SRAS on the digested soil residue (AS 4969.6).
