皮革.用液相色谱法对皮革中防腐剂（TCMTB PCMC OPP OIT）含量的化学测定.第2部分:人工汗液提取法

[中文适用范围]： 本标准规定了采用液相色谱法测定皮革中下列防腐剂水可萃取物含量的人工汗液水萃取试验方法： ——2-(硫氰基甲硫基)-苯并噻唑(TCMTB)； ——4-氯-3-甲基苯酚（PCMC）； ——2-苯基苯酚（OPP）； ——2-辛基异噻唑-3(2H)-酮（OIT）；该方法还可用于测定这些防腐剂的分解产物，这些防腐剂可保护皮革免受微生物侵袭。 [外文原描述]： This document specifies a test method by artificial perspiration solution aqueous extraction for the determination of the aqueous extractable content of the following preservative agents in leather by liquid chromatography: — 2-(thiocyanomethylthio)-benzothiazole (TCMTB); — 4-chloro-3-methylphenol (PCMC); — 2-phenylphenol (OPP); — 2-octylisothiazol-3(2H)-one (OIT); This method can also be used to determine breakdown products of these preservative agents, which protect leather from microbiological attack.
