Application Summary AI generated

This standard specifies the tetrachloromercurate (TCM)-pararosaniline spectrophotometric method for determining sulfur dioxide (SO₂) concentration in ambient air. It is applied in environmental monitoring stations and air quality assessment programs to measure SO₂ levels in outdoor atmospheres, particularly for compliance with ambient air quality standards and pollution control studies. The method is suitable for manual sampling and laboratory analysis of air samples collected from urban, industrial, or background monitoring sites.
