Preface: To carry out the environmental protection law of the People's Republic of China "and the law of the People's Republic of China on the prevention and control of atmospheric pollution, protect the environment, safeguard human health, standardize the determination method of sulfur dioxide in the air, these standards are formulated. This standard is to the environment air so2 determination of formaldehyde absorption by pararosaniline - spectrophotometric method "(GB/T 1 Revision of the 5262-94). Since the date of implementation of this standard, the original approval of the state environmental protection agency on October 26, 1994, the state environmental protection standards issued by the "environmental air so2 determination of formaldehyde absorption by pararosaniline - spectrophotometric method" (GB/T 15262-94).   
Description:This standard stimulates the determination of sulfur dioxide in ambient air formaldehyde absorption by pararosaniline - spectrophotometric method.
This standard applies to the determination of sulfur dioxide in ambient air.
When using 10 ml absorbing liquid, sample volume of 30 l, determination of sulfur dioxide in air of the detection limit of 0.007 mg/m < 3 > superscript, determination of limit of 0.028 mg/m < 3 > superscript, determination of upper limit of 0.667 mg/m (superscript 3 >.
When using a 5 0 ml absorbing liquid, sample volume is 288 l, try a 10 ml, determination of sulfur dioxide in air of the detection limit of 0.004 mg/m < 3 > superscript, determination of lower limit of 0.014 mg/m < 3 > superscript, determination of upper limit of 0.347 mg/m (superscript 3 >.
