Cobaltate -, silver rubidium

Robertson [ 57 ] has measured the adsorption of zinc, caesium, strontium, antimony, indium, iron, silver, copper, cobalt, rubidium, scandium, and uranium onto glass and polyethylene containers. Radioactive forms of these elements were added to samples of seawater, the samples were adjusted to the original pH of 8.0, and aliquots were poured into polyethylene bottles, Pyrex-glass bottles and polyethylene bottles contained 1 ml concentrated hydrochloric acid to bring the pH to about 1.5. Adsorption on the containers was observed for storage periods of up to 75 d with the use of a Nal(Tl) well crystal. Negligible adsorption on all containers was registered for zinc, caesium, strontium, and...

The radionuclides commercially available and most commonly used for a number of the foregoing applications include anhmony-125 banum-133, 207 bismuth-207 bromine-82 cadmium-109, 115 m calcium-45 carbon-14 cerium-141 cesium-134, 137 chlorine-36 chromium-51 cobalt-57, 58, 60 copper-64 gadolimum-153 germanium-68 gold-195. 198 hydrogen-3 (tritium) indium-111, 114 m iodine-125, 129, 131 iron-55, 59 krypton-85 manganese-54 mercury-203 molvbdenum-99 nickel-63 phosphorus-32. 33 potassium-42 promethium-147 rubidium-86 ruthenium-103 samarium-151 scandium-46 selenium-75 silver-110 m sodium-22, strontium-85 sulfur-35 technetium-99 thallium-204 thulium-171 tin-113, 119 m, 121 m. titamum-44 ytterbium-169, and zinc-65. 

Salt. When compared on a molar basis, the mineral ion salts (ammonium, calcium, rubidium, copper, silver, lead, manganese, cobalt, potassium, and sodium, and cyclohexylamine salt) were as effective as the free gibberellic acid in promoting stem elongation (10,14). As shown in Figure 1, the potassium and zinc salts of A3 were as active as the acid in promoting the growth of d-1 dwarf maize.

The inclusion of iron, cobalt, nickel, and certain other metals in Group VIII.4 enables the alkali-metals lithium, sodium, potassium, rubidium, and caesium to be placed in their natural position as a subgroup of Group I. of the periodic system, in juxtaposition to the related sub-group containing copper, silver, and gold (p. 3). This arrangement...

A very considerable number of elements has been shown to occur in a wide range of animal tissues and fluids in such minute amounts that they can appropriately be described as traces. Numerous studies of biological materials from widely separated sources have established the fact that copper, manganese, zinc, iodine, cobalt, nickel, aluminum, chromium, tin, silicon, titanium, lead rubidium, lithium, molybdenum, arsenic, fluorine, bromine, barium, and strontium are commonly present in low concentrations in blood, milk, and tissues of higher animals, and other metals, such as silver, gold, boron, cadmium, and cerium are occasionally present. No doubt others will be detected as more-refined analytical methods are developed. 

Variable Micro-constitaents.—Lithium, Rubidium, Caesium, Silver, Beryllium, Strontium, Cadmium, Oermanium, Tin, Lead, Arsenic, Chromium, Cobalt, Nickd, Aluminium, Molybdenum, Barium.—Some of these have only been detected in a few species, and their functions are obscure.
