[Capillary gas chromatographic determination of residual benzene, toluene and DMF in acrylic fabrics].

Jin Mc, Fu Zm, L Wang

Abstract

A simple method for the analysis of residual benzene, toluene and N,N-dimethyl formamide (DMF) in acrylic fabrics by wide-bore capillary gas chromatography is presented. The sample was extracted by carbon disulfide (CS2) for an hour. The results showed that this is a rapid and sensitive method with less interferences and fairly good precision. The detection limits were 0.1, 0.1 and 2.0 ng for benzene, toluene and DMF respectively. The recoveries were 93.3%-101.8% and coefficients of variation were 2.0%-3.4%.
