In this work, the utilization of iron(II) hydroxide (Fe(OH) 2 ) slurry as the absorbent in wet flue gas desulfurization was investigated. The most important reason for selecting Fe(OH) 2 is that iron sulfate, formed by captured sulfur dioxide, can be converted back to Fe(OH) 2 . First, in the experiments, a bubble column was used with continuous gas and liquid flow. Second, perforated plates were used in the same column. Lastly, a magnetic field was applied to this multiplate bubble column so that the flow of Fe(OH) 2 slurry could be affected by the magnetic field because of the electric charge of Fe 2+ . It was found that the multiplate bubble column performed better than the single‐stage bubble column, and application of the magnetic field further enhanced the absorption efficiency.
