Absorption of nitrogen dioxide in organic solvents.
The absorption of NO(2) at low levels in nitrogen, by N,N-dimethylformamide (DMF) and dimethyl sulphoxide (DMSO), has been investigated. Parts-per-million levels of NO(2), were collected with an efficiency of 90% in DMF and 65-70% in DMSO. The absorption efficiency in DMF depends on the gas flow-rate and the bubbling time, but in DMSO it is independent of time.
