In this investigation, as an altemative to the traditional use of low rank coals, we prepared cationic xanthated exchangers from a subbituminous coal (67.6% C, 4.6% H, 22.4% O, 0.6% S, 3.2% ashes and 46.2% volatile matter) of Montelibano-Córdoba; this exchanger showed better exchange capacities for cadmium and lead (1.8 meq/g) than traditional sulphonated exchangers (0.56 and 1.11 meq/g for cadmium and lead respectively). Xanthation was verified at 30 ºC and at 5-10 ºC with NaOH and CS2. Toe best performance of xanthation, determined by Infrared spectrometry and ion exchange experiments, occurred at low temperatures maybe due to CS2 volatility. By diminishing the particle size of coal the exchange capacity increased. The exchange capacity was evaluated by flame atomic absorption spectrometry.
