增塑剂对1,1,1-三[1′-(2′-氧杂-4′-氧代-5′-氮杂-5′-甲基)十二烷基]丙烷PVC膜钠离子电极性能的影响 总被引:2,自引:0,他引:2
以1,1,1-三[1′-(2′-氧杂-4′-氧代-5′-氮杂-5′-甲基)十二烷基]丙烷(即ETH 227,Fluka No.71732)为中性载体的钠离子选择电极由于具有较强的抗钾离子干扰的能力,因而颇受注意。Guggi等首先用邻硝基苯辛醚和癸二酸二丁酯增塑,以合成的ETH227制成了K_((Na)~+,K~+)~(pot),<<10~(-2)的PVC膜钠离子电极.Jenny等以癸二酸二异辛酯为增塑剂, 相似文献

The complexes of rare earth picrate with N,N,N',N'-tetraphenyl-3,6-dioxaoctanediamide(TDD),Eu(picc(TDD)] 2CH3CN and [ Y(pic)3(TDD)],have been synthesized.The crystal structures reveal that TDD at is as n tetradentate ligand,forming a ring-like coordination structure with its oxygen atoms together with one oxygen atom of the bidentate pterate In the Eu(Ⅲ) complex,the europium ion with a larger ionic radius lies out of the ring,while in the Y(Ⅲ) complex,the yttrium ion with a smaller ionic radius enters the cavity of the ligand.The structures of the complexes are greatly affected by the ionic radii due to participation of the picrates in coordination. 相似文献
