| Abstract |
Description of a method of determining concentration levels of the bactericide sulfadimethoxine and of its intermediates (6-amino-2,4-pyrimidinediol; 4-amino-2,6-dichloropyrimidine; 4-amino-2,6-dimethoxypyrimidine). Analysis is based on diazotisation of the air sample and coupling of the product with resorcinol. Optical density of the resulting pink coloration is in direct proportion to the concentration of sulfadimethoxine, and may be determined by spectrophotometry. The calibration curves for the 3 basic substances are given. |
