Abstract

Cyanotoxin is one of the emerging water contaminants that pose serious health risks to humans. high performance liquid chromatography and liquid chromatography-mass spectrometry (LC-MS) are commonly used analytical tools for the detection and quantification of cyanotoxins. Recommended Environmental Protection Agency drinking water guidelines for majority of cyanotoxins is 1 µμg L and is followed by majority of drinking water treatment plants to ensure public health and safety. Ozone is an effective method for removing cyanotoxins present in water. Some stable cyanotoxin species can be removed by ozone-based advanced oxidation processes. UV irradiation and H2O2 when used along with ozone, and TiO2 catalyzed ozonation can accelerate the cyanotoxin removal process in water. Water chemistry plays an important role in determining the efficiency of advanced oxidation processes. This paper summarizes the recent studies that are carried out targeting the removal of cyanotoxins in water, and evaluates benefits of ozonation as a pre- or post-oxidation process for drinking water desalination plants.
