In a waste management context, predicting the mobility of contaminants is essential. A key issue entails assessing the applicability of current knowledge on adsorption processes to natural systems. Such is the focus herein for nickel in interaction with Callovo-Oxfordian (COx) clay rock, a formation selected in France for possible radioactive waste disposal. The challenge is to link predictive modeling results with the experimental data characterizing the behavior of the labile and naturally occurring Ni fraction by implementing a new simple method. Retention studies on compact systems serve to complete this work. Combined electron microprobe and laser ablation high-resolution inductively coupled plasma mass spectrometry data show that natural Ni (∼39 mg kg–1) is homogeneously distributed within the clay matrix, which corresponds to the main reservoir (∼70%). Data interpretation of desorption tests yields an in situ K d value of ∼80 L kg–1 and a labile Ni amount of ∼5 mg kg–1, that is, ∼13% of the Ni inventory. Predictive modeling explains the sorption data in considering that only weak clay fraction sites take part in the adsorption. The role of the clay matrix in Ni retention is confirmed by analyzing the Ni-spiked compact COx samples, whereby an increase of the Ni content in the clay fraction is observed following the retention experiment.

“…The obtained sample weights varied from 10 to 40 mg. The digestion procedure has been described elsewhere (Hassan Loni et al, 2019) and proves to be suitable for low-mass samples. The wood sections were washed in 0.1 M HNO3 for about an hour and then dried in an oven for 7 h at 70°C (until achieving constant weight).…”

“…The ablated material was removed from the sample chamber by helium carrier gas, then mixed with argon gas and directly introduced into the hot plasma of the HR-ICP-MS instrument. Operating conditions have been detailed elsewhere (Hassan Loni et al, 2019). The Eu concentration was determined by external calibration using two standard reference materials, i.e.…”
