Abstract
A method for the determination of selenium by preconcentration and thermal neutron activation is presented. Selenium is adsorbed on active charcoal after reduction to the elemental state. By varying the conditions of the reduction, it is possible to measure the total selenium content and tetravalent selenium separately. The contribution of hexavalent selenium is obtained by substraction. The lower limit of determination is 5 ng°1−1. About 40 samples per day can be handled by one analyst. The preconcentration can be performed at the sampling site resulting in samples, which can be stored easily for later analyses by neutron activation.
