1.1 本试验方法包括使用固相萃取（SPE）从水中提取、使用液相色谱（LC）分离和使用串联质谱（MS/MS）检测的双酚A（BPA）的测定。用该方法对BPA进行了定性和定量测定。该测试方法遵循多重反应监测（MRM）质谱法。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 BPA的方法检测限（MDL）和报告限（RL）列于 表1 。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 首次报道的BPA的合成是通过Zincke使苯酚与丙酮反应。 4. BPA已成为一种重要的大体积工业化学品，用于制造聚碳酸酯塑料和环氧树脂。聚碳酸酯塑料和树脂用于许多产品，包括电气和电子设备、汽车、体育和安全设备、可重复使用的食品和饮料容器、印刷电路板的电气层压板、复合材料、油漆、粘合剂、牙科密封剂、保护涂层和许多其他产品。 5. 5.2 BPA的环境来源主要来自聚碳酸酯塑料和树脂的分解。BPA未被美国环境保护局归类为生物累积型，会被生物降解。据报道，BPA对水生生物有不良影响，并可能通过垃圾填埋场渗滤液和POTW废水以微量水平直接释放到环境水中。该方法已被研究用于地表水和二级和三级POTW出水样品，因此，它仅适用于这些基质。它尚未被研究用于盐水或固体样品基质。

1.1 This test method covers the determination of bisphenol A (BPA) extracted from water utilizing solid phase extraction (SPE), separated using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). BPA is qualitatively and quantitatively determined by this method. This test method adheres to multiple reaction monitoring (MRM) mass spectrometry. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 The method detection limit (MDL) and reporting limit (RL) for BPA are listed in Table 1 . 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The first reported synthesis of BPA was by the reaction of phenol with acetone by Zincke. 4 BPA has become an important high volume industrial chemical used in the manufacture of polycarbonate plastic and epoxy resins. Polycarbonate plastic and resins are used in numerous products including electrical and electronic equipment, automobiles, sports and safety equipment, reusable food and drink containers, electrical laminates for printed circuit boards, composites, paints, adhesives, dental sealants, protective coatings and many other products. 5 5.2 The environmental source of BPA is predominantly from the decomposition of polycarbonate plastics and resins. BPA is not classified as bio-accumulative by the U.S. Environmental Protection Agency and will biodegrade. BPA has been reported to have adverse effects in aquatic organisms and may be released into environmental waters directly at trace levels through landfill leachate and POTW effluents. This method has been investigated for use with surface water and secondary and tertiary POTW effluent samples therefore, it is applicable to these matrices only. It has not been investigated for use with salt water or solid sample matrices.
