“…9 Evaluation of 3.6 ppb of U at different pH in the range of 0.5-2.5 and in the presence of 5 ppm of copper and 2.7×10 −3 M EDTA and 9.2×10 −7 M CAA and a very selective method. Almost no interferences are caused either by major cations nor by anions in ground water (Singhal et al 2004). Observed interference caused by deposition of surface active dissolved substances like DOC on Hg electrode is taken care of by the destruction of organic compound by wet digestion.…”

“…This information is vital as metal bioavailability is considered be linked to the truly dissolved fraction, which is operationally defined as the phase with molecules smaller than 10 kDa (~5 nm) [5]. The ultrafiltration technique is neither limited by ionic strength nor by complexation equilibria and it has been used for the uranium speciation measurements in freshwater [6], estuaries [7] and in coastal seawaters [8]. Nevertheless, a vigorous and intricate handling protocol needs to be followed and possible contamination during transport and storage cannot be ruled out.…”
