Abstract: This article describes the adsorptive behavior of Maifanshi for the Iodine,Calcium and dCTP in the solution. Maifanshi has a Comparatively weak ability to adsorb anion Iodine. only 4.5%of Iodine can be adsorbed. However, Its ability.to adsorb Cation Calcium anddCTP is rather strong. adsorptivity is 85% and 92% respectively. The adsoption for the Iodine will reach the equilibrum value in 4.5%hours. The adsorption for the Calcium will reach the peak Volue in 4.5 hours. In the case of the adsorption for dCTP the eguilibrum value will be achievedLin 22.5 hours.
