Lead (II) and cadmium (II) are metal ions what can organ damage to death. Tuna fish bone coated by alginate (TIA) has been used in the sorption of lead (II) and cadmium (II) metal ions in conditions gastric acid pH. TIA has been characterized using Fourier Transform Infrared (FTIR), Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), and X-Ray Diffraction (XRD). TIA has better stability than fish bone (TI), calcium alginate, and alginate in acidic pH as indicated by the reduction data of adsorbent mass in a solution of nitric acid pH 1,2. The adsorption capacity of TIA to lead (II) and cadmium (II) were 26,37, 40,07 and 48,63 mg g-1 and 15,47, 16,06, and 16, respectively, 84 mg g-1 with an adsorbent size of 20, 30, and 60 mesh. The amount of lead (II) absorbed by TIA with the amount of adsorbent 0.1 - 0.5 g is 30,4 - 100% at a concentration of 50 ppm, <br /> <br /> <br /> <br /> 27,9 - 100% at a concentration of 100 ppm, and 78.7 - 100% at a concentration of 200 ppm. The amount of cadmium (II) absorbed by TIA with the amount of adsorbent 0,1 – 0,5 g is 7,3 - 67,1% at concentration 50 ppm, 7,1 - 67,4% at concentration 100 ppm, and 14,8 - 736% at a concentration of 200 ppm. Adsorption of alginate coated bone (TIA) to lead (II) and cadmium (II) ions in gastric acid pH conditions following a pseudo-second kinetics model. <br />
