摘要
酚类属高毒物质,水中挥发酚的含量直接影响人类健康。在用4-氨基安替比林(4-AAP)法测定挥发酚中,影响因素很多,如:样品预处理、试剂纯度、显色萃取操作等问题,在测定过程中操作不当均会给分析结果带来误差。针对挥发酚的测定中可能出现的问题,从三大方面进行研究探讨,为提高测定挥发酚的精密度和准确度提供科学依据。
Volatile phenols were highly toxic substances and it's content in water directly affected human health. There were many influencing factors on tlhe determination of volatile phenols by 4 - aminoantipyrene (4 - AAP ) spectrophotometry, such as sample pretreatment, reagent purity, coloration and extraction operation, etc. The improper operation can led an inaccurate result. To :solve the problems which may happen on the process of the determination of volatile phenols, three aspects were researclh to provide the scientific basis to improve it~ precision and accuracy.
