A radio-release technique for determining traces of elements

摘要: A radio-release technique for the determination of traces elements is described. small amount an insoluble compound fixed on a disc filter paper or other suitable material. The exchangeable ions this are labelled with radioactive isotope and then replaced trace element to be determined in solution. After released from carrier into solution by shaking, activity species measured compared one, or, series standards processed same way. In first communication, method mercury, which applicable contents > 0.25 μg per ml, presence several including bismuth, lead, thallium, cadmium copper, advantages limitations discussed.
