Abstract:
A simple and sensitive method for extracting an inorganic element, including toxic metals such as lead or antimony or non-metallic elements such as arsenic, selenium or tellurium from animal blood, including human blood, is provided by the present invention. The sample of blood or portion of blood, such as red cells, is first mixed with an neutral salt solution. The mixture of cells and buffer is then exposed to a chelating resin which removes the inorganic element, such as lead, from solution. Thereafter, the resin is packed in a column and the element, such as lead, is eluted. The amount of eluted element, such as lead, is measured by conventional methods, such as atomic absorption spectrophotometry.
