  • Title: Diazinon determination using high performance liquid chromatography: a comparison of the ENVI-Carb column with the immunoaffinity column for the pretreatment of water and soil samples.
    Author: Tang J, Zhang M, Cheng G, Lu Y.
    Journal: Bull Environ Contam Toxicol; 2009 Nov; 83(5):626-9. PubMed ID: 19590806.
    Abstract:
    An immunoaffinity chromatography column was developed to remove diazinon from water and soil samples. In this paper, two types of absorbent columns, the immunoaffinity chromatography column and the ENVI-Carb column, were compared. To accomplish this, each of these columns was used to treat water and soil samples that had been spiked with diazinon at concentrations of 2.5 or 5 ng/mL (or ng/g). High performance liquid chromatography was then used to analyze the treated samples. The ENVI-Carb column recovered 87.99%-95.95% of the diazinon from water and soil with CVs of 5.08%-8.06%. The recoveries observed when the immunoaffinity chromatography column was used were slightly lower (52.61%-81.58%); however, it effectively clean up the soil samples.
