Copper (I) iodide, silica powder and calcium sulfate (CaSO_4・1/2H_2O) were mixed and made into tablet as dried Hg-absorbing agent. Absorbing ability was tested in several composition by AAS using silver amalgam. Mixing ratio of each chemicals that showed superior absorbing ability was 1:1:1 in weight. As mercury (I) iodide shows vermilion color, the absorbing ability can be observed easily by surface color change. This tablet can be more easily handled than potassium permanganate-sulfuric acid solution absorbent in wet state.
