Permeation of a malathion formulation through butyl gloves

摘要

The factors that determined the permeation kinetics of a commercial malathion formulation (Prent) and its reconstituted cocktail of malathion and its xylene-range fraction inert ingredients at Prent concentrations (Recon) were investigated for an unlined unsupported butyl industrial type Glove in an ASTM-type permeation cell with liquid 2-propanol collection and subsequent analysis By gas chromatography/mass spectrometry. For both Prent and Recon. The steady-state perme- Ation rate P_s corrleated inversely with the logarithm of the breakthrugh time t_b, as did log P_s With log T_b. P_s, log p_s, P_s/t_1 and log P_)s/T_1 (where t_1 is the lag time) versus the logarithm of the Weight percentage o component divided by the total weight were linear too.
