Patent number: 11975988Abstract: The determination of hydroxyl radical scavenging capacity of contaminated water can be achieved by developing an external calibration model. The model can be prepared using standard solutions where scavenging capacities are determined, and then the solutions are treated with addition of an oxidant and a dye, followed by UV treatment to form hydroxyl radicals that are scavenged by species in the standard solution. The residual dye content can then be measured using absorbance. The absorbance and the scavenging capacity data for the standard solutions are used to build the model, which can then be implemented to determine scavenging capacity of contaminated water. Water samples can be subjected to the same treatment as the standard solutions, the absorbance of the water sample is then obtained, and then the model is used to determine the corresponding scavenging capacity. Determining scavenger capacity of contaminated water can aid in advanced oxidation processing (AOP).Type: GrantFiled: January 17, 2019Date of Patent: May 7, 2024Assignee: THE GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTOInventors: Ronald Hofmann, Chengjin Wang, Erik Rosenfeldt
