Ozone combined with ultraviolet radiation (A, = 254 nm) has been shown to oxidize atrazine in water. The process can be used to oxidize different organic compounds such as volatile organochlorine substances (e.g., pesticides). Mass transfer and kinetic data have been applied to the mass balance equations of atrazine to obtain corresponding concentrations under varying...

The uncertainty for the determination of e.g. atrazine in water consists of the calibration of several components of uncertainty, such as the uncertainty of the true content of the atrazine standard, uncertainty from dilution of this standard, uncertainty regarding the loss of atrazine in sampling and storage prior to analysis, as well as that associated with the preconcentration step after correction for recovery.

Sym-TRiAZiNE Chromophobe. The spectrum of simazine and atrazine in water (Figure 8) shows a weak band at 263 /x which is to be compared with the 7T — 7T (255 /x) band of benzene. Another intense band at 220 /x is observed which is characteristic of all the substituted m-triazines (Table IX). 

Triazines such as atrazine, propazine or simazine, are widely used herbicides. Currently, the determination of atrazine in water and soil samples is mainly done by GLC (1,2) or HPLC (3-5). However, these procedures require cumbersome cleanup steps which could be avoided by using immunoassays as an alternative approach to residue analysis. Such immunochemical determination based on competitive binding of herbicides or pesticides to an antibody (6,7), has been described recently for s-...
