IUVA Education Resource Center

Research Repository

Our Guiding Principles

The resources will include important past publications that cover some fundamental findings in UV applications. The co-Chairs are experts in environmental/water applications, so input will be sought from experts in other relevant areas as needed to identify important resources.

Newer groundbreaking studies will also be linked. The top journals will be reviewed for relevant research and the expertise of the area co-Chairs will be used to decide which studies are selected to be linked. Access to some of the resources may require subscription. The resources will also include important protocols and standardization approaches used in UV research.

Roberta Hofman-Caris, KWR Water Research Institute

Olya Keen (PE), University of North Carolina

Roberta Hofman-Caris is a Senior Scientist at KWR Water Research Institute, associate professor at Utrecht University of Applied Sciences and visiting scientist at Wageningen University and Research, all located in the Netherlands.. Dr. Hofman-Caris started out as a scientific journalist, and then spent two decades as a chemical researcher before moving into water treatment. Today she focuses on both drinking water and wastewater treatment with emphasis on advanced oxidation processes, and resource recovery. She’s currently involved in research for drinking water treatment, especially UV oxidation techniques and adsorption processes for the removal of micropollutants, resource recovery, remediation and lifecycle assessment. She is a member of the IUVA Board of Directors.

Olya Keen (PE) is an Associate Professor of Civil and Environmental Engineering at the University of North Carolina at Charlotte. Dr. Keen’s research expertise areas are photolysis and advanced oxidation processes for water and wastewater treatment. She has been involved in this research field since 2009 with her early work focused on the fate of contaminants of emerging concern in AOP and on fundamental chemistry and photochemistry of the process, with the more recent efforts focused on standardization, method development and process improvement for UV-based AOPs.

Vacuum UVAbsorption Coefficients of Water Vapor in the Vacuum UltravioletWatanabe, K, Zelikoff, Murray

Absorption coefficients of water vapor in the region 1060–1860A were obtained by a photoelectric method described previously. Pressures (0.08 to 8 mm Hg) of water vapor in the absorption cell were measured with an Alphatron gauge. In the region 1860–1500A, the absorption coefficients were between the values reported by two groups of investigators.
