Mercury has drawn the public's concern due to its bio-accumulative nature and its adverse impact on human health. At the same time, concern for greenhouse gas release has also grown, leading to a range of carbon capture strategies. Previous mercury removal studies, however, focused on either dry techniques or acidic solution conditions, and a major uncertainty is how high alkalinity (which is used in carbon mineralization capture methods) may result in a different mercury removal mechanism. To examine this question in detail, in this study, a lab-scale liquid-gas scrubbing system is manufactured and installed, based on the
