Abstract

Complexation of nickel with fulvic material in groundwater taken from the Drigg research site has been studied using a high pressure size exclusion (HPSEC) technique involving GPC-60 and GPC-100 size exclusion columns. The groundwater was preconcentrated by rotary evaporation by a factor of ten, doped with 63Ni and allowed to reach equilibrium. The water showed three major peaks. The organic peak eluted first has been identified as fulvic acid. The two subsequent peaks have narrow UV absorbances and are ascribed to inorganic nickel complexes, possibly Ni(OH)(+) and free Ni, i.e. Ni(H(2)O(6))(2+).
