In this HOT paper António Rangel from Universidade Católica Portuguesa, Portugal, and colleagues have developed an automated optosensor to determine levels of bromate in drinking water. The sensor was based on the formation of a colored radical cation after oxidation of chlorpromazine by bromate. Bromate is a by-product of chemical water treatment, and this new sensor can detect levels that meet the requirements of current EU and USA legislation.
