Abstract

The manganous sulphate bath method is widely used for measurements of neutron source strength. In this study, the analytical chemistry method based on the argon supported inductively coupled plasmas emission spectrometry was used for examining the impurity contents of domestic $MnSO_4{\cdot}H_2O$ the product of Chemical Industry, to induce $^{55}Mn(n,{\gamma})^{56}$ Mn reactions. From the analytical results, mainly potassium, cobalt, and zinc as well as trace amounts of cadmium, lithium, etc. have turned out to be the relevant impurities absorbing the neutrons, and the fraction of neutrons absorbed by the total impurities was calculated. The value obtained was about 1.37% of the neutrons captured by manganese.
