Special Report No. 80-07: A Laboratory Examination of the Use of the ASTM/APHA Spectrophotometric Method for the Measurement of Methyl Mercaptan in Kraft Pulp Mill Workspace Atmosp

Special Report No. 80-06 described the findings of a laboratory examination of the utility of commercially available detector tubes for the measurement of methyl mercaptan in the kraft mill workspace. This special report is a companion to Special Report No. 80-06 and describes the laboratory examination of the ASTM/APHA spectrophotometric method for the measurement of methyl mercaptan in kraft pulp mill workspace atmospheres. The study showed that the method, when slightly modified, was capable of satisfactory recovery of methyl mercaptan.
