Abstract
Two methods were compared for quantitative determination of phosphine present on fumigated food and materials. The rate of desorption of PH3 by using a purge-and-trap method was shown to be much slower when compared with sulfuric acid treatment and was also simpler. Application of the modified sulfuric acid treatment for real samples is described.
摘要
比较了两种定量测定熏蒸食品和材料中磷化氢的方法。结果表明，与硫酸处理相比，采用吹扫捕集法时PH3的解吸速率要慢得多，而且也更简单。描述了改进的硫酸处理方法在实际样品中的应用。
