The impurity removal method removes impurities in an exhaust gas and includes forming a froth layer in a tank, by blowing the exhaust gas into an absorbing liquid contained in the tank via a gas dispersion pipe, wherein, given that a proportion of the gas occupying the froth layer is defined as a gas holdup, impurities such as soot dust included in a gas such as an exhaust gas is removed efficiently and at a low cost by setting a gas holdup in the froth layer to be 0.4&#x2dc;0.9, setting a height of the froth layer to be 0.2&#x2dc;1.8 m, and setting a gas-liquid contact area per unit volume of the froth layer to be 1500&#x2dc;2500 m/m.
