| 内容記述 | Cryogel is super-macroporous material prepared by freezing of polymer or monomer solution at low ternperature. The hybrid material of cryogels and iron hydroxide oxide（FeOOH） nano-particles, which have affinity to arsenic, are expected as a safe removal adsorbent of arsenic ions from aqueous solutions. ln this study, polyacrylamide（PAA） cryogels containing FeOOH particles were prepared by freezing the monomer solution of acrylamide cross-linker N,N-methylene bis（acrylamide） dispersing the particles, which were prepared by mixed iron（III） chloride solution （FeCl3） and alkaline aqueous solution, and polymerizing initiated by N,N,N',N'-tetramethyl ethylene diamine and ammonium peroxodisulfate at sub-zero temperatures. The particles formed were observed on a whole of the cryogel wall. The polyacrylamide cryogel containing FeOOH particles successfully adsorbed a large amount of As（V） at both low and high concentrations. The adsorption property showed a Brunauer-Emmett-Teller（BET）-like isotherm. The adsorption of As（V） with the cryogel was not affected by the pH value of the aqueous solution. On the other hand, that of As（lll） with the cryogel was affected by the only pH 12 of the aqueous solution. The FeOOH particles entrapped in the cryogel waIl had a poorly crystaIline. The poorly crystaline FeOOH particles had higher adsorption capacity than the crystalline ones. | |||||
