| 摘 要： | 利用薄层色谱（TLC）、紫外光谱（UV）、反相高效液相色谱（RPHPLC）对多环芳烃（PAHs）萘、蒽、芘的分析方法进行了研究。TLC中使用环己烷：氯仿（5：4，V／V）作为展开剂时，三者的R，值分别为0．78、0．65和0．72；用UV法在溶液中测定了三者的最大吸收波长分别为303、380、338nm；当流动相为甲醇：水（9：1，V／V）时三者在RP—HPLC中的保留时间为4．179、5．190、6．178min，5次重复RSD分别为1．1％、1．8％、0．91％，并用于实际水样中萘、蒽、芘的分析。

| Abstract: | The analytical methods of TLC, UV, RP-HPLC for analyzing three Polycyclic Aromatic Hydrocarbons (PAHs), i.e. naphthalene, anthracene and pyrene, were studied. The Rf values of naphthalene, anthracene and pyrene, were developing agent in TLC. The maximum absorption wavelengths in UV spectra of naphthalene, anthracene and pyrene were 303, 380, 338 nm, respectively. The retention values of naphthalene, anthracene and pyrene in RP-HPLC were 4.179, real water sample were analyzed. |
