Jhe distribution of beryllium, boron, titanium, vanadium, chromium, cobalt, nickel, copper, zinc, gallium, germanium, tin, molybdenum, yttrium, and lanthanum in the principal coal-producing beds of the Interior Province has been studied by the U. S. Geological Survey. Data, methods of sampling, and analyses are discussed by Zubovic and others (II, 12). This chapter discusses the occurrence of 13 of these elements with respect to geological and geochemical environments of coal deposition and chemical properties of the elements. Zinc and tin are not included in this study because they were detected in only a few samples. 

These alloys are available as wrought or cast alloys. The principal wrought copper alloys are the brasses, leaded brasses, phosphor bronzes, aluminum bronzes, silicon bronzes, bciylhum coppers, cupronickels. and nickel silvers. The major cast copper alloys include the red and yellow brasses, manganese, tin, aluminum, and silicon bronzes, beryllium coppers, and nickel silvers. The chemical compositions range widely. For example, a leaded brass will contain 60% copper, 36 to 40% zinc, and lead up to 4% a beryllium copper is nearly all copper, containing 2.1% beryllium, 0.5% cobalt, or nickel, or in another formulation, 0.65% beryllium, and 2.5% cobalt.

Phenol can be produced directly from benzene by use of N2O as an oxidizing agent in the gas phase. Catalysts are modified ZSM-5 or ZSM-11 materials, containing elements such as antimony, arsenic, beryllium, boron, cobalt, chromium, copper, gaUium, indium, iron, nickel, scandium, vanadium or zinc.

Microcomponents Inorganic microcomponents cover almost the entire periodic table. Here we discuss only those elements that are determined most frequently beryllium, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic, selenium, silver, cadmium, antimony, barium, and lead. The techniques of choice are FAAS, graphite furnace-AAS (GF-AAS), ICP, and hydride generation-AAS (HG-AAS). An ultrasonic nebulizer has recently become commercially available for FAAS and ICP-AES, which decreases the lower determination limits. ICP-mass spectrometry (ICP-MS) is a recent development in which ionization is combined with sensitive mass discrimination. In a further development a graphite furnace is used in front of the ICP-MS. Selective evaporation of elements in the graphite furnace reduces the influence of highly interfering matrices. ICP-MS is expensive, which deters its widespread use. 

Beryllium copper n. Copper containing about 2.7% beryllium and 0.5% cobalt, used for blow molds and insertable injection-mold cavities. The small percentages of Be and Co greatly increase the strength and hardness of the copper whole preserving its high thermal conductivity and corrosion resistance. Beryllium copper is easily pressure cast and bobbed into mold cavities. 

Alloys having litde or no sensitivity are claimed to be 7075-T6 aluminum Haynes 188 (cobalt-base) beryllium copper (copper-base) Types 304, 316, and 310 austenitic stainless steels Type 430 high-hardness ferritic steel and age-hardened austenitic A286 steel. Titanium-base alloy T1-6A1-4V exhibits moderate sensitivity. Alloys with high sensitivity are Haynes 25 (cobalt-base) and iron-base alloys, including medium- and high-strength steels. 

Coordination centers studied include beryllium, lanthanum, cerium, titanium, zirconium, thorium, uranium, chromium, manganese, iron, cobalt, nickel, copper, zinc, cadmium, aluminum, tin, and lead. Many nonmetallic elements have been incorporated into the bridging groups and side groups, so that, in all, some 30 elements have been included in polymers of the phosphinate type. Of most interest are some of the polymers with tetrahedral and octahedral centers. 

Copper/beryllium alloys (thermal conductivity 200 W/mK) and copper/cobalt/ beryllium alloys (225 W/mK) for nozzle casings and tips in applications up to aromid 280 C (see Figure 4.5a) (because of the mechanical strength of the alloy, which rapidly falls when the temperature rises). Treatment involving an overlayer of silicon carbide increases injection abrasion resistance with, for example, PA and GF. Nickel coating eliminates the influence of copper on the melt (electroless nickel plating) ... 

Another type of design is the nozzle with copper/cobalt/beryllium alloy casing located inside a steel body bearing an external load (Figures 4.17b and 4.17c). In a nozzle used with reinforced plastics and plastics with an injection temperature of over 280 °C, the casing is made of molybdenum. The nozzle may have a full- or partial-body 4.17(b).

Samples Analyzed by Inductively Coupled Plasma (ICP) Metals — Where two or more of the following analytes are requested on the same filter, an ICP analysis may be conducted. However, the Industrial Hygienist should specify the metals of interest in the event samples cannot be analyzed by the ICP method. A computer print-out of the following 13 analytes may be typically reported Antimony, Beryllium, Cadmium, Chromium, Cobalt, Copper, Iron, Lead, Manganese, Molybdenum, Nickel, Vanadium, Zinc. Arsenic — Lead, cadmium, copper, and iron can be analyzed on the same filter with arsenic. 

The procedure utilises eriochrome blue black RC (also called pontachrome blue black R Colour Index No. 15705) at a pH of 4,8 in a buffer solution. Beryllium gives no fluorescence and does not interfere iron, chromium, copper, nickel, and cobalt mask the fluorescence fluoride must be removed if present. The method may be adapted for the determination of aluminium in steel.
