This standard specifies two methods for the determination of sulfur ion content in coal mine water: p-aminodimethyl aniline Colorimetry and iodimetry. P-aminodimethyl aniline Colorimetry is suitable for the determination of sulfur Ion concentration in the range of 0.08 to 1.00 mg/L, while iodimetry is suitable for the determination of sulfur Ion concentration above 1.00 mg/L. The principles, required reagents and related steps of the two methods are described in detail.
