“…In the determination of trace elements in iron and steel, the separation from the matrix is effected by the use of anionexchange procedures using hydrochloric acid solutions (292,473). A preconcentration on an anion-exchange resin was used in the determination of parts per billion amounts of chromium in water (449). An anion-exchange method was also used as the separation procedure for the determination of chromium in tungsten (21 1 ) .…”

“…Radionuclide (for example, 131I) losses occur during evaporation on a water bath. Because the weak emitters (14C,3H,210Pb,90Sr, 95Nb, and 228Ra) cannot be detected with common detectors, the routine determination of the total beta activity in water can be designated only as an approximation method.…”
