IMMOBILIZATION OF CESIUM BY CRYSTALLINE ZIRCONIUM PHOSPHATE WITH THREE DIMENSIONAL NETWORK STRUCTURE

以ZROCl2、H3PO4和H2C_2O_4为原料，CSNO_3/HZR_2(PO_4)_3=0.4为固定化产物，经水热反应预先合成NH_4Zr_2(PO_4)_3，经700℃热分解制得HZR_2(PO_4)_3。含有最大固载量的CS(CSNO_3/HZR_2(PO_4)_3的摩尔比为0.4wt%，约相当于CS的10wt%)，在高压反应釜中，在160℃的几种溶剂中，CS的浸出率最低。产品中CS离子浸出率分别为1.0×10~(-6)、1.0×10~(-6)、10~(-6)、4.7×10~(-5)、2.2×10~(-4)和2.1×10~(-3)天。在去离子水、海水、0.1MOL L-1-1-HCl、0.5MOL L-1-HCl、1MOL L-1-HCl、1.5MOL L-1-HCl和1MOL L^-1&>NH_3中，HZR_2(PO_4)_3与CSNO_3反应生成稳定的CS固定化产物。而SR(NO_3)_2/HZR_2(PO_4)_3=0.2700℃热处理的固定化产物具有最大的AMO…更多的固定SR(SR(N0_3)_2/HZR_2(PO_4)_3的0.2摩尔比，约相当于SR的4WT%)在160℃的几种溶剂中有最小的SR释放速率，表明HZR_2(PO_4)_3与SR(NO_3)_2反应得到稳定的SR固定化产物。设H是一个有限维点Hopf代数，作用在质环R上，Q是R的对称马丁德商环，K是Q，K的中心U是R的中间子环，A是包含K的K#H的右余模子代数。首先，对S.Westreich在1999年给出的关于H在R上作用的Galois-型对应理论的一个结果，我找到了一个反例。作为与Westreith联合工作的一个结果，我们证明了关于Q#H的(R#H，U)-子双模的一个性质的I Emma，这意味着给出Galois对应的映射是内射的。我们还证明了如果基域的特征为零，则Λ是某个右余模子代数上的分裂扩张。由此，我们给出了一个新的证明，证明了对应映射是满射的，并在特征为零的情况下，得到了有限维点Hopf代数在素环上的X-外作用的Caiois型对应理论。较少

HZR_2(PO_4)_3 WAS PREPARED BY THE THERMAL DECOMPOSITION OF NH_4ZR_2(PO_4)_3, WHICH WAS SYNTHESIZED IN ADVANCE BY A HYDROTHERMAL REACTION FROM A STIRRED SOLUTION OF ZROCL_2, H_3PO_4 AND H_2C_2O_4-THE CSN0_3 / HZR_2(PO_4)_3 = 0.4 IMMOBILIZED PRODUCT, TREATED AT 700℃, CONTAINING THE MAXIMUM AMOUNT OF IMMOBILIZED CS (A 0.4 MOLAR RATIO OF CSN03 / HZR_2(PO_4)_3 EQUATES TO APPROXIMATELY 10 WT% OF CS) WAS MINIMAL CS LEACHING RATES IN SEVERAL SOLVENTS AT 160℃ IN AN AUTOCLAVE. THE LEACHING RATE OF CS ION FROM THAT PRODUCT WAS <10^<-6>, 1.0 x l0^<-3>, <10^<-6>, <10^<-6>, 4.7 x 10^<-5>, 2.2 x l0^<-4> AND 2.1 x 10^<-3> G M^<-2> DAY^<-1> IN DEIONIZED WATER, SEAWATER, 0.1 MOL L^<-1> HCL, 0.5 MOL L^<-1> - HCL, 1 MOL L^<-1> - HCL, 1.5 MOL L^<-1> - HCL AND 1 MOL L^<-1> NH_3, RESPECTIVELY, INDIOATING THAT HZR_2(PO_4)_3 REACTS WITH CSN03 TO GIVE A STABLE CS-IMMOBILIZED PRODUOT. ON THE OTHER HAND, THE SR(N0_3)_2 / HZR_2(P0_4)_3 = 0.2 IMMOBILIZED PRODUCT THERMALLY TREATED AT 700℃, CONTAINING THE MAXIMUM AMO … More UNT OF IMMOBILIZED SR (A 0.2 MOLAR RATIO OF SR(N0_3)_2 / HZR_2(P0_4)_3 EQUATES TO APPROXIMATELY 4 WT% OF SR), WAS MINIMAL SR LEACHlNG RATES IN SEVERAL SOLVENTS AT 160℃ INANAUTOCLAVE, INDICATING THAT HZR_2(P0_4)_3 REACTS WITH SR(N0_3)_2 TO GIVE A STABLE SR-IMMOBILIZED PRODUCT.Let H be a finite dimensional pointed Hopf aigebra acting on a prime ring R in an X-outer way, Q the symmetric Martindal e quotient ring of R, K the center of Q, U an intermediate subring of R and A a right comodule subalgebra of K#H containing K. First, I found a counterexample to a result on a Galois-type correspondence theory for the action of H on R given by S. Westreich in 1999. As a resul t of a joint wcrk with Westreith, we showed a I emma on a property of (R#H, U)-subbimodules of Q#H, which implies that the map giving a Galois correspondence is injectivb. We also proved that if the characteristics of the base field is zero, then Λ is a cleft extension over a certain right comodule subalgebra. From this fact, we can give a new proof showing that the correspondence map is surjective and obtain a Caiois-type correspondence theory for X-outer actions of fini te dimensional pointed Hopf algebras on prime rings in the case the characteristics is zero.
