Action of copper sulphate upon iron meteorites

The Action of Copper in Iron Metabolism*

The importance of copper as a supplement to iron for hemoglobin regeneration in anemic rats was first demonstrated 4 years ago by Hart, Steenbock, Waddell, and Elvehjem (1). This work showed definitely that in the presence of copper, soluble inorganic iron salts can be used directly for hemoglobin formation. Since that time a number of workers have studied factors affecting hemoglobin productio...

Microanalysis of Niobium in Iron Meteorites

Introduction: Niobium and tantalum are generally regarded to be lithophile incompatible elements occurring in chondritic relative proportions in planetary materials [1]. Precise Nb/Ta data have indicated that Nb may be depleted in the Earth's mantle [2, 3] which may be evidence for sequestering in an eclogite reservoir [2], or for its removal into the core [3, 4]. Metal-silicate partitioning ex...

Copper Sulphate and Disinfection of Water

lime, which, added in even so small an amount as 0 000426 gramme to a hundred cubic centimetres of water, kills all the micro-organisms within two hours. The bacteria appear to be acted upon much more promptly than the other organic matter present. For the removal of the excess of the agent the addition of sulphite of sodium (0 000209 gm.) suffices, and an excess of this substance up to 50 per ...
