Abstract

Reaction times for 16 acid sulfate soil materials analysed using a modified chromium-reducible sulfur method varied between 10 and 15 min, regardless of whether the samples had been dried and ground prior to analysis or were analysed without pretreatment. The reaction time for a ground (<63 μm) pyritic rock sample was 20 min. An optimum reaction time of 20 min is recommended for analysing acid sulfate soil using the modified method; this reaction time is much less than the 1 h reaction time used in previous methods.
