Abstract
A comparison study was undertaken to evaluate different analytical methods for measuring B concentrations in the geothermal fluid from the Los Alamos Hot Dry Rock Geothermal Energy Project [New Mexico, USA] and from natural waters collected in the vicinity of the project. Three colorimetric techniques, the carmine method and 2 azomethine H methods, were compared with 2 plasma emission spectroscopy methods and with thermal neutron capture .gamma.-spectroscopy. The analytical results from all methods were comparable and acceptable; each method had its own distinct advantages and disadvantages.
