Abstract
A method was developed for the determination of MBTS and TCMTB in wastewaters. The method development program consisted of: a literature review; determination of extraction efficiency for each compound from water into methylene chloride; development of a deactivated silica gel cleanup procedure; and determination of suitable high performance liquid chromatographic (HPLC) analysis conditions. Recoveries of MBTS from distilled water ranged from 76 to 94 percent at concentrations ranging from 10 to 1000 micrograms/l. Recoveries of TCMTB from distilled water were greater than 85 percent at concentrations ranging from 10 to 1000 micrograms/l. The method detection limit (MDLs) for MBTS and TCMTB as determined in distilled water were 0.5 and 1.0 micrograms/l, respectively. The MDLs in wastewaters may be higher due to interfering compounds. The final method was applied to Publicly Owned Treatment Works (POTW) secondary effluent to determine the precision and accuracy of the method.
