Cornell, S. Aksoyoglu] Batch sorption experiments using nickel have been carried out on marl, a sedimentary, carbonaceous rock. All experiments were performed with a synthetic water of pH 7.3 and in an atmosphere of N2/1% CO2. Over the equilibrium nickel concentration range of 10−11-10−5M, sorption was linear and reversible with Rd of 819 ml g−1. Owing to the linear sorption behavior, Rd was independent of rock/water ratio (r/w=1/5-1/100). The data suggested that at [Ni] lower than 10−7M an isotope exchange mechanism operated, whereas at higher [Ni], sorption involved ion exchange. Sorption experiments on some of the components of marl indicated that nickel adsorbs mainly on the clay minerals and on the trace of iron hydroxide present; sorption on calcite and quartz was low.
