Online differential UV aborbance for DBP estimation

差示紫外分光光度法（DUVS）可以作为一种相对简单，快速，低成本的替代品， 受管制的三卤甲烷（THMs）和卤乙酸（哈斯），可以帮助市政当局克服 他们在管理这些有害物质的水平方面的问题。它是基于这样一个原则， 氯化前后在特定波长处的UV吸光度的差异可以与某些 DBP。在线分光光度计“探头”，如水生生物有限公司， 用于现场真实的时间估计、监测和控制消毒副产物的可能性 （消毒副产物）在水处理厂通过DUVS的原则。目前这类应用的瓶颈是 特定环境（即不同的水质特征导致无法概括的紫外光谱），以及 可操作的（例如，絮凝材料或沉淀物阻塞光路）。该项目旨在开发一个 协议，使水生生物有限公司利用水的紫外光谱之间的潜在的强相关性 在处理链的不同阶段（即消毒之前和之后）和目标DBP化合物。

Differential UV spectrophotometry (DUVS) can be used as a relatively simple, fast, and low-cost surrogate for regulated trihalomethanes (THMs) and haloacetic acids (HAAs) that could help municipalities to overcome their problems with managing the levels of these unwanted substances. It is based on the principle that differences in UV absorbance at specific wavelengths before and after chlorination can be correlated to certain DBPs. Online spectrophotometer "probes" such as those from Aquatic Life Ltd. lend themselves particularly useful for the possibility of in situ real time estimation, monitoring and control of disinfection by-products (DBPs) in water treatment plants through the principles of DUVS. Current bottlenecks for such applications are context-specific (i.e. varied water quality characteristics resulting in UV spectra that can't be generalised) and operational (e.g. blockage of light path by flocculent material or precipitates). This project seeks to develop a protocol to enable Aquatic Life Ltd. to exploit the potentially strong correlations between UV spectra of water at different stages of a treatment chain (i.e. before and after disinfection) and DBP compounds of interest.
