“…(1 ppb) is attained. He (47,48) has also described the polarographic analysis of reactor water to the ppb level through the use of ethylenediaminetetraacetic acid (EDTA). Pohl points out that the usual control of water purity by conductivity fails by an order of magnitude to provide the needed sensitivity and that oxide corrosion products are not detected by the measurement.…”

The analysis of ultra-pure water by quiescent evaporation in Teflon (Du Pont) followed by spectrography of the residue isdescribed. The preparation of ultra-pure water by distillation and by deionization is reviewed. The product attained by deionization in metal apparatus is shown to be subject to significant contamination by metallic constituents, presumably present in nonionized form. This contamination may not be revealed by measurement of conductivity. The necessity for a specific analysis for contaminants is indicated. The desirability of constructing apparatus from inert materials (fused quartz, polyethylene, Teflon) is emphasized. Water having as metallic contaminants no more than approximately 1 ppb each of Ca, Mg, AI, and Si may be prepared by appropriate techniques of distillation or ion exchange.

“…Regular control of reactor coolant and moderator water is necessary in order to detect cations, the presence of which is "forbidden" for technical and for health safety reasons. A method based on measurements of electrical conductivity is insufficient when the impurities are present in nonionized form [1). Chemical analyses are too tedious and time-consuming for routine use.…”

An adaptation of the copper spark excitation method of spectrochemical analysis is presented for the determination of boron and strontium in reactor waters. The Intensities of the analytical lines BII‐3451.41A and SrII‐4077.714A were determined photometrically and related to the concentrations of B and Sr. The method covers the ranges 5 × 10−7 to 7.5 × 10−6% and 2.5 × 10−7 to 5 × 10−6% for B and Sr respectively. The method was extended to lower concentrations by five superimposed exposures (the limits of detection then being 10−7% for B and 5 × 10−8% for Sr), and it can be extended even further, when necessary, by use of a greater concentration factor and/or mote superimposed exposures. The method is simple and rapid, and yet adequately sensitive and precise. The coefficients of variation for single determinations of B and St content are about 10% and 14% respectively.
