  The Demospongiae was used in Kish Island of Persian Gulf as the biologic absorptive with nano fovea  for removing magnesium action and the effect of density, contact time and the size of the absorptive particle was studied in absorption capacity. The absorption capacity of magnesium ion in 10, 30, 50 and 300 mg /l was tested on shaker and the capacities of 0.7, 3, 6.6, 80.3 mg/g were obtained respectively which showed that the absorption capacity increases with density. In addition, the absorption of magnesium ion in the densities of 10, 30 and 50 mg/l,  in contact time of 1 hour without shaker,  were 1.2, 4.2, 11 and in 3 hours,  0.2, 4.6 and 14.5 mg/g,  which showed that the absorption capacity does not increase with contact time. The absorption capacity in absorbent size of 70 meshes and 120 meshes were 80.3, 64.6 and 74.2 mg/g respectively, which showed that the absorption capacity is more when used in pieces. The results of the present research showed that the absorption capacity of magnesium ion by Persian Gulf sponge is 80.3 mg/g and the reported ratio is higher compared to other natural absorbents and is now the highest capacity.
