Maximum efficiency of water treatment programs requires precise control of chemical concentrations. Detecting low levels of non-oxidizing biocides can be difficult in the field and is further complicated by water turnover and, in some cases, the natural degradation of the chemical. At the same time, ever-increasing concerns about effluent toxicity make it desirable to have this capability. An antibody-based immunoassay has recently been developed for the industrial biocide 2,2-dibromo-3-nitrilopropionamide (DBNPA) which provides for the fist time a sensitive and selective field-friendly method of analysis.
Keywords: 2,2-Dibromo-3-nitrilopropionamide, DBNPA, immunoassay, antibody.
