Inductively coupled plasma atomic emission spectrometric determination of arsenic, antimony, tin, bismuth, selenium and tellurium in leads and refined coppers

Abstract

Methods were developed for the determination of As, Sb, Sn, Bi, Se and Te in leads and refined coppers using both direct sample solutions and the hydride generation technique. For hydride generation in coppers, prior separation of the matrix was necessary owing to the inhibiting effect of copper on hydride formation. For leads, it is possible to generate hydrides for As, Sb, Bi and Se directly from test solutions. Tin and Te require prior separation of the matrix in order to avoid lead precipitation in the hydrochloric medium suitable for the generation of the tin hydride in the former instance and the inhibition produced by lead in the latter. The dissolution of samples, separation processes, sample treatment, choice of analytical lines and measurable concentration levels were investigated.

Determination of 22 trace elements in high-purity copper including Se and Te by ETV-ICP OES using SF6, NF3, CF4and H2as chemical modifiers

“…[42][43][44] Inductively coupled plasma optical emission spectrometry (ICP OES) and ICP-MS are mostly accepted analytical methods for the multielement trace determination in solutions of decomposed pure metals. ICP OES was used for pure copper 45,46 also combined with the hydride generation technique. 47 The capability of HR-ICP-MS for multielement trace determination in high purity copper was investigated 35,36,48,49 and compared with those of ICP-MS and ICP OES.…”

Determination of trace elements in high-purity copper by ETV-ICP OES using halocarbons as chemical modifiers

“…[39][40][41] Today inductively coupled plasma optical emission spectrometry (ICP OES) and inductively coupled plasma mass spectrometry (ICP-MS), the latter one in combination with quadrupole mass spectrometers (ICP-QuMS) or with high resolution sector field spectrometers (ICP-HR-MS), are mostly accepted analytical methods for the multielement trace determination in solutions of decomposed pure metals. The ICP OES can be applied to the determination of many trace elements in pure copper 42,43 also in combination with the hydride generation technique. 44 Matschat et al investigated the capability of ICP-HR-MS for the multielement trace determination in pure metals, among them copper, 45,46 and they compared it with the analytical capability of ICP-QuMS and ICP OES.…”
