가죽 — 액체 크로마토그래피에 의한 가죽 내 방부제(TCMTB, PCMC, OPP, OIT) 함량의 화학적 측정 — 제2부: 인공 땀액 추출법 皮革液相色谱法测定皮革中防腐剂(TCMTB、PCMC、OPP、OIT)含量的化学方法第2部分:人工排汗法
发布日期: 2023-11-16
该标准规定了人工汗水溶液提取法的试验方法,以通过液相色谱法测定皮革中下列防腐剂的水溶性提取物含量。2-(赛奥西亚诺甲基赛奥)-苯并噻唑[2-(thiocyanome thylthio)-benzothiazole)](TCMTB);-4-氯-3-甲基苯酚(4-chloro-3-methylphenol)(PCMC);-2-苯酚(2-phenylphenol phenol)(OPP);-2-辛基异噻唑-3(2H)-lon[2-octylisothiazol-3(2H)-one](OIT);该方法也可用于测定保护皮革免受微生物攻击的这些防腐剂的分解产物。
이 표준은 액체 크로마토그래피에 의해 가죽 내 다음의 방부제의 수용성 추출물 함량을 측정하기 위해 인공 땀 수용액 추출법에 의한 시험방법에 대하여 규정한다. —2-(싸이오시아노메틸싸이오)-벤조씨아졸[2-(thiocyanomethylthio)-benzothiazole)](TCMTB); —4-클로로-3-메틸페놀(4-chloro-3-methylphenol)(PCMC); —2-페닐페놀(2-phenylphenol)(OPP); —2-옥틸아이소씨아졸-3(2H)-론[2-octylisothiazol-3(2H)-one](OIT); 이 방법은 미생물 공격으로부터 가죽을 보호하는 이러한 방부제의 분해 산물을 측정하는 데에도 사용할 수 있다.
