基于感官检验和气相色谱-离子迁移谱法分析食用 油脂加工厂污水处理过程的挥发性物质Analysis of volatile compounds in wastewater treatment process in edible oil plant based on sensory examination and GC-IMS
为高效鉴定食用油脂加工厂污水处理过程的气味组成,采用感官检验以臭阈值量化不同处理工序污水的臭味浓度,并采用气相色谱-离子迁移谱法(GC-IMS)对其挥发性化合物进行分析,并对鉴定出的挥发性化合物进行指纹图谱和主成分分析。结果表明:污水经过处理臭阈值明显降低;GC-IMS鉴定出43种化合物,基本均为含氧有机物,包括酮类、醇类、醛类、酯类、酸类及其他类;总体上各处理工序污水挥发性物质总数和臭阈值的变化规律一致;各处理工序挥发性化合物存在一定差异。综上,GC-IMS是分析食用油脂加工厂污水处理过程气味变化的有效方法。 In order to effectively identify odorant...
