Water analysis

Instrumental analysis in waste water treatment

“…Another disadvantage is that only one metal can be determined at a time. Various techniques for dealing with these problems have been widely reported in the literature, and reviews have been published in this JOURNAL (7,8).…”

“…Increasing interest in ultra trace concentrations of metals in the environment has resulted in the use of several techniques for enhancing the sensitivity of AAS analyses. Perhaps the best known are the various microsam-pIe devices consisting of various electrically or flame-heated boats, ribbons, cups, and furnaces (7,8). By far, the most popular has been the electrically heated graphite tube based on the original concept ofL'Vov (9).…”

Water analysis

“…It is removed by extraction with methyl isobutyl ketone before addition of thenoyltrifluoroacetone. At 5 and 50 Mg/L relative standard deviations are 7 and 1%, respectively. Satake et al (27B) used the combination of chelating ion-exchange separation and atomic absorption spectrometry to determine manganese in brackish and coastal waters.…”

Pneumatoamperometric determination of parts-per-billion dissolved species by gas evolving reactions

“…The high toxicity and low allowable limits for these and other toxic species illustrate the need for sensitive analytical methods. Numerous articles describing methods for these and related analyses have appeared in recent years and are reviewed biannually (2)(3)(4).…”
