Absorption of lean formaldehyde from air with Na2SO3 solution

“…Then, the mass transfer coefficients in the reaction system can be determined with the help of Eqs. (5) and (6), t. Table 1 shows the values of these coefficients, together with the parameter used to calculate them. The model derivation starts from the mass transfer rate of formaldehyde into a reaction solution, which can be written as:…”

“…Different researchers have indicated that some catalysts [4][5][6], solid absorbents and adsorbents have effective functions on formaldehyde removal. For instance, metal oxides [7], ammonium salts [8] and Fe-phosphate-ammonium oxalate composites [9] can be good cleaning materials of formaldehyde.…”
