Abstract
A method was developed for the determination of oryzalin in wastewaters. The method development program consisted of a literature review; determination of extraction efficiency of oryzalin from water into methylene chloride; development of a deactivated Florisil cleanup procedure; and determination of suitable liquid chromatographic analysis conditions. A method to determine oryzalin in wastewaters was developed. Extraction and cleanup procedures were developed to provide 85 percent or greater recoveries of oryzalin from wastewater. A high performance liquid chromatography (HPLC) method of analysis with ultraviolet detection (UVD) was also developed. The final method was applied to a relevant industrial wastewater in order to determine the precision and accuracy of the method. The method detection limit (MDL) for oryzalin in distilled water was 0.5 micrograms/l. The MDL in wastewaters may be higher due to interfering compounds.
