Abstract: The method for the purification of a gas containing pollutants, particularly fumes, comprising the following steps of: providing a purification apparatus comprising a hollow body defining a purification chamber; feeding of a gas to be purified inside the purification chamber; first dispensing operation of nebulized water inside a first portion of the purification chamber to intercept the gas to be purified for the abatement of the organic and/or inorganic compounds present in the gas itself; treatment of the gas coming out of the first portion in a second portion arranged downstream of the first portion in the direction of gas flow; second dispensing operation of nebulized water inside a third portion of the purification chamber, arranged downstream of the second portion in the direction of gas flow; where nebulized water comprises deuterium and where the treatment comprises the formation of electric discharges in the second portion to ionize the gas coming out of the first portion and to obtain a state of pl
