Process water from oil sand operations contains chemicals such as scale or corrosion inhibitors added during bitumen processing as well as soluble organics from the bitumen. Under a zero discharge policy, all process water must be stored on-site in tailings ponds. Since the environmental fate of many of these chemicals is unknown, their widespread use has raised increasing concerns due to their potential impact on downstream aquatic ecosystems when the water containing these chemicals seeps into the environment during operations or when it is discharged into the environment after operations (although some sort of water treatment will almost certainly be needed before such release is allowed). To determine the fate of these chemicals, one should selectively detect them and quantify their amount in the environment. In this study, a new HPLC-MS/MS method was developed to measure some typical process chemicals. Using this method, inorganic salts were separated from the chemicals without any sample pre-treatment, and the ionic and non-ionic surfactants were detected and quantified. This method will be useful in the determination of potential impacts of individual process chemicals on the environment.

使用HPLC-MS / MS定量测定水中多种表面活性剂

油砂作业产生的工艺水包含在沥青加工过程中添加的化学物质(例如水垢或腐蚀抑制剂)以及沥青中的可溶性有机物。根据零排放政策,所有过程用水必须在尾矿池中现场存储。由于许多此类化学品的环境命运尚不得而知,因此,当含有这些化学物质的水在作业过程中渗入环境或在作业后排放到环境中时,会对下游水生生态系统产生潜在影响,因此它们的广泛使用引起了越来越多的关注。 (尽管几乎肯定会在允许释放之前进行某种水处理)。为了确定这些化学物质的命运,应该有选择地检测它们并量化其在环境中的含量。在这项研究中,开发了一种新的HPLC-MS / MS方法来测量一些典型的过程化学品。使用这种方法,无需进行任何样品预处理即可从化学品中分离出无机盐,并对离子型和非离子型表面活性剂进行检测和定量。该方法在确定单个过程化学品对环境的潜在影响时将很有用。
