Table 6 Adsorption <strong>of</strong> iodine species in fresh water onto activated charcoal previously washed with double<br />
distilled water and/or ethanol. The total concentration (iodide + iodate + organic iodine) in <strong>the</strong> Danish lake<br />
water used in all experiments was 20.6 ppb. The volume <strong>of</strong> water was 200ml in all experiments.<br />
