Determination of microamounts of lead in copper, nickel

1972/8/1Atomic absorption spcctromctry has recently become an increasingly impor- tant tool in a Held of trace analysis for impurities in metals and alloys. Elwell and Gidley1 have reported the determination of larger amounts (0.05-5%) of lead in copper-base alloys and

Direct determination of trace metals in solid samples by

2001/1/1A method for the direct determination of lead in high- and low–alloy steels and in nickel–base alloys has been developed. The solid samples containing 0.2–60 μg Pb g -1, are inserted into a Varian-Techtron CRA90 graphite cup held at constant temperature (1800C).

Determination of trace impurities in some nickel compounds by flame atomic

ties of metallic nickel, nickel-base alloys, compounds and catalysts can be affected by certain impurities [1]. There-fore, the determination of trace impurities in these materi-als is important. The direct determination of lead, bis-muth, gold, palladium, cadmium

Determination of bismuth in nickel

1978/12/1Atomic absorption spectrometry with an induction furnace is applicable'to the determination of bismuth at 0.02–10 μg g-1 levels in 1–30-mg samples of nickel-base alloys dropped into the furnace. Calibration graphs of peak absorbance versus mass of bismuth are constructed by use of standardised alloys.

1996/10/101.1 This test method covers the determination of lead in nickel and nickel alloys in the concentration range of 0.00005 % to 0.001 % by electrothermal atomic absorption spectrometry. Note 1-If this test method is used to test materials having contents less than

Atomic Absorption Determination of Lead, Bismuth,

The determination of lead, bismuth, selenium, tellurium, thallium, and tin was successfully demonstrated by direct atomization from complex, nickel-base alloy chips with commercial atomic absorption furnace equipment. The determination was carried out by first

Determination of lead, bismuth, zinc, silver and antimony in

A fast and simple method of determining lead, bismuth, zinc, silver and antimony in steel and nickel-base alloys has been developed using unmodified commercial atomic-absorption equipment. The method is based on the direct atomisation of solid metal samples in

Determination of trace impurities in iron and nickel

1977/7/1Five approaches to the determination of trace amounts of lead, bismuth, thallium, selenium, tellurium, and silver in iron and nickel-based alloys were investigated. While all procedures produced satisfactory results, direct techniques yielded a significant times advantage over separation schemes.

Determination of trace amounts of thallium and tellurium

A method is described for determining trace amounts of Tl in nickel-base alloys using pre-treatment with ammonia solution and electrothermal atomic absorption spectrometry. Thallium was coprecipitated when the sample solution of a nickel-base alloy was treated

ISO 11437

This part of ISO 11437 specifies an electrothermal atomic absorption spectrometric method for the determination of lead in the range of 0,5 g/tonne to 10,0 g/tonne in nickel alloys. The general requirements concerning the apparatus, sampling, dissolution of the test sample, atomic absorption measurements, calculation and test report are given in ISO 11437-1 .
