空气中丙烯酰胺的测定曾有报道羟胺一氯化铁比色法,但该法灵敏度低,采样量大,现场采样不方便。本文根据丙烯酰胺能与溴水反应生成α,β—二溴丙酰胺的原理,试验了空气中丙烯酰胺的气相色谱法。并对方法的溴化条件,采样效率及样品的稳定性进行了实验,现将方法及实验结果报告于后。 Determination of acrylamide in the air has been reported hydroxylamine ferric chloride colorimetric method, but the method of low sensitivity, sample size, on-site sampling inconvenient. In this paper, based on the principle that acrylamide can react with bromine water to produce α, β-dibromopropionamide, the gas chromatographic method of acrylamide in air was tested. And the method of bromination conditions, sampling efficiency and stability of the sample were tested, the method and the experimental results are reported later.
