“…Atomic Absorption. Several reports have appeared de-scribing the atomic absorption determination of copper in dissolved steels to which various reagents have been added to reduce interelement effects (62,151,204,464). In several other cases reported, solvent extraction with propylene carbonate (643) and an electrographic technique for surface analysis ( 622) have been used for sample pretreatment.…”

This review covers the period from November 1974 through October 1976, and is a continuation of previous reviews. The search of Chemical Abstracts was aided by the Knowledge Availability Service Center at the University of Pittsburgh. Following nearly all citations in the Literature Cited, the Chemical Abstract (CA) volume and abstract numbers are given.Because of the worldwide interest in manganese nodules, references to the analysis of this material are cited. Special references are also made to papers describing surface-analysis techniques and data acquisition and reduction with the aid of microprocessors and computers.

“…Begak and Pokrovskaya (10) have studied the effects of the concentration of HC1, HNO3, H2SO4, HCIO4, H3PO4, and some binary mixtures of these on the signal strength of Ca in atomic absorption determinations. They determined that HCIO4 (0.02 to 0.3M) increased the absorption, whereas H3PO4 (0.1 to 1.0M) suppressed the absorption.…”
