Abstract
A method was developed for the determination of mercaptobenzothiazole 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 liquid chromatographic analysis conditions. Extraction and cleanup procedures were developed to provide 79 percent or greater recoveries of mercaptobenzothiazole from the wastewater. An HPLC analysis method with ultraviolet detection was also developed. The final method was applied to Columbus secondary Publicly Owned Treatment Works (POTW) effluent in order to determine the precision and accuracy of the method. The wastewater was spiked with mercaptobenzothiazole at levels of 5 micrograms/l and 100 micrograms/l. Recovery for mercaptobenzothiazole at the 5 microgram/l level was 79 + or - 5 percent. Recovery at the 100 microgram/l level was 87 + or - 4 percent. The method detection limit (MDL) in distilled water was 1.7 micrograms/l. The MDL in wastewaters may be higher due to interfering compounds.
