Some problems may arise with respect to As and Hg. Cu, Cd and Ni can only be determined if present in high concentrations. Separation by adsorption on charcoal in presence of complexing agents gives yields between 75 and 100% for the following elements in sea water: Ag, Au, Cd, Ce, Co, Cr, Eu, Fe, Hg, La, Mo, Sc, Se, U, Zn (As 67%, Sb 56'%). Activation or use of labelled ions and study of exchange give information about mobility of trace elements in suspended matter.en0022-4081Journal of radioanalytical chemistry19772717726Kluwer Academic Publishershttp://doku.b.tu-harburg.de/doku/lic_ohne_pod.phpNeutron activation as a routine method for the determination of trace elements in waterJournal Articleurn:nbn:de:gbv:830-tubdok-459810.15480/882.38511420/38710.1007/BF0251938410.15480/882.385930767671Other
