| Outline of Final Research Achievements |
For developing arsenic removal adsorbent from water, the hybrid material of cryogels and iron hydroxide oxide(FeOOH) nano-particles, which have an affinity to arsenic, are successfully prepared using in situ particle formation and particle addition methods. The adsorption properties of arsenic(V) were investigated using the batch adsorption and the column flow adsorption systems. The adsorption amount of As(V) per weight of the FeOOH particles in the cryogel increased with a decrease in the FeOOH amount in the cryogel. The FeOOH particles entrapped in the cryogel wall prepared by the particle addition method was an amorphous in which that had higher adsorption capacity of As(V) than that having higher crystallinity by the in situ particle formation method. The arsenic adsorption rate to the cryogel was high enough to keep high adsorption amount of arsenic(V).
