Preface: Implementation of the environmental protection law of the People's Republic of China, the law of the People's Republic of China on the prevention and control of atmospheric pollution, protect the environment, safeguard human health, standard monitoring method of ammonia, these standards are formulated. This standard on the air quality sodium hypochlorite - salicylic acid spectrophotometric method for determination of the ammonia "(GB/T14679-93) to revise. Since the As of the date of implementation of this standard, the former state environmental protection agency released on October 27, 1993, approved, the state environmental protection standards "air quality sodium hypochlorite - salicylic acid spectrophotometric method for determination of the ammonia" (GB/T 14679-93).   
Description:This standard stimulates the determination of ammonia in the air of sodium hypochlorite - salicylic acid spectrophotometric method.
This standard applies to the determination of ammonia in ambient air, can also be applied to the stench source factory bound the determination of ammonia in the air.
The method detection limit of this international standard is 0.1 mu g / 10 ml of absorption liquid. When the total volume of absorbing liquid to 10 ml, compressed volume of 1 ~ 4 l, ammonia detection limit of 0.025 mg/m < 3 > superscript, determine the lower limit of 0.10 mg / < superscript 3 >, the determination of upper limit of 12 mg/m (superscript 3 >. When the absorption liquid product for 10 ml, sampling volume 25 l, ammonia detection limit of 0.004 mg/m < 3 > superscript, determine the lower limit 0.016 mg/m (superscript 3 >.
