A New Simulation Chamber for the Study of Atmospheric Iodine Chemistry

Design, construction and characterisation of an atmospheric simulation chamber

Funding Body: Science Foundation Ireland

Project type: PhD

Period:  January 2008 – January 2011

Researcher: Enowmbi Robertina Ashu-Ayem

Project Description

Design, construction and characterisation of an atmospheric simulation chamber. The chamber will consist of an FEP Teflon bag (with a volume of approximately 2.6m3) and a 2kW Xenon arc lamp for photolysis.

An in-situ Incoherent Broadband Cavity Enhanced Absorption Spectroscopy (IBBCEAS) will be used to detect the presence of trace atmospheric gases. Special interest will be on Iodine emitted from a selected species of seaweed. Iodine species such as I2, CH3I and Iodine oxide radicals, IO and OIO will be monitored.
