Abstract: | A reactor fast neutron activation analysis was used in combinationwith a simple pre-concentration procedure for determining silicon in someiron reference standard materials of Japan Iron and Steel Federation. Thesamples were dissolved with aqua regia and digested with perchloric or sulfuricacid. The precipitated silica was collected on a filter paper and irradiatedin a cadmium case with reactor fast neutrons. Silicon can be determined intool steel SKD6, low-alloy steel Nos 2 and 4 and silico-manganese samplesby a present method measuring 1,273.4 keV rays from 6.63-minute 29Alproduced by 29Si(n,p)29 Al reaction. |
