- W906278785 abstract "用卟啉类显色剂测定钴的研究还较少,而且已报道的均为水溶性卟啉。鉴于非水溶性卟啉合成及提纯容易、产率高、种类多等优点,本文在研究非水溶性α,β,γ,δ-四苯基卟啉(简称TPP)与Cu(Ⅱ)、Pd(Ⅱ)、Cd(Ⅱ)等配合反应的基础上又研究了该试剂与Co(Ⅱ)的反应。在阴离子表面活性剂十二烷基硫酸钠(SDS)存在下,利用咪唑加速催化Co(Ⅱ)对Cd-TPP配合物的置换反应,使Co(Ⅱ)与TPP形成了很稳定的配合物。e 435 =3.02×10 5 L·mol -1 ·cm -1 。是目前卟啉类试剂测定钴较灵敏的方法,测定维生素B 12 中钴,结果满意。" @default.
