Title: [The improvement of determination method of carbon disulfide in workplace air with gas chromatography].
Abstract: Establishment of determination method of carbon disulfide in charcoal tube with low toxicity solvents desorption-gas chromatography.Four types of solvent with low toxicity are applied respectively as substitution of benzene to desorb the carbon disulfide in samples of charcoal tube. The signal strength and desorption efficiency of the detector are compared by using different solvents.Chloroform has been considered as the best alternative solvent of benzene. Carbon disulfide has a good linearity (R = 0.9997) over the concentration of 0 ∼ 54.7 µg/ml, detection limit can reach 0.2 µg/ml. When the sampling volume is 3.0 L, the minimum detectable concentration is 0.07 mg/m(3).With the use of chloroform, the health hazard to laboratory personnel and environment pollution as well as the costs of experiments are reduced.
