Sampling and breakthrough studies with plictran.
Chemical Hazards in the Workplace, Measurement and Control, ACS Symp Ser 1981; :109-121
Dual filter combinations for sampling tricyclohexyltin-hydroxide (13121705) (Plictran) were tested. Aerosol samples of Plictran were generated under controlled laboratory conditions. Glass fiber and cellulose ester filters were tested in direct contact in two piece, 37 millimeter field cassettes and separated in three piece, 37 millimeter field cassettes. Filtration sampling was compared to impingement of the sample into concentrations of nitric-acid. A concentration equal to 150 parts per million (ppm) Plictran or 46.2ppm tin(IV) (22537504) was used as the aerosol. The samples were digested and prepared. An atomic absorption spectrophotometer, equipped with a graphite atomizer head, was used to analyze all samples. A tin, hollow cathode lamp was used to generate the desired wavelength. Working tin standard solutions of 0.3 to 1.0 microgram per milliliter were prepared. Concentrated nitric-acid appeared to be the better collector of Plictran than any filter combination. There appeared to be no breakthrough of Plictran from the first filter. Coated filters did not appear to be more efficient than non coated filters, but more data was needed to complete such a comparison. The authors conclude that Plictran can be safely collected with a single glass fiber filter.
