SUMMARY Gamma radiation as an alternative sterilization technique for silt and clay suspensions is evaluated. It is compared to autoclaving in regard to sterility and changes in physical and chemical properties of the suspensions. A minimum radiation dose rate of 5 kGy s?1 led to sterilization and no changes in lattice structure or precipitation of the suspensoids were observed. The adsorbed ionic composition of the silt and clay particles was, however, altered and should be rectified before radiated suspensoids are used. Autoclaving resulted in sterility, but irreversible precipitation of the suspensoids made it less applicable where the colloidal properties of the clay and silt are to be maintained. 相似文献

1. The rule of addition of solubilities is applicable to the differentiation of the oxyhemoglobins of not too closely related species. 2. The oxyhemoglobins of the horse, dog, rat, and guinea pig show differences when tested by this method. The oxyhemoglobins of the donkey and horse show a similarity which is best explained by the assumption of isomorphism. 相似文献
