Abstract
Silicon determination in sixteen botanical and biological standard ref erence materials is described using the Si-29(n, p)Al-29 reaction thro ugh instrumental epithermal neutron activation analysis and Compton su ppression gamma-ray spectroscopy. By simultaneous utilization of both cadmium and boron epithermal filters along with anticoincidence gamma- counting, detection limits as low as 12 ppm were obtained for certain matrices, much lower than previously reported values for this type of analysis. The method is applicable to many botanical and biological ma trices and is attractive with its interference free, purely instrument al nature, compared with methods using the Si-28(n, p)Al-28 reaction o r chemical separation techniques.
