3.2. CMC–metal ion complexes CMC form polymer complexes with transition metal ions. The binding sites in Cr (III) and Ni (II) complexes were the etheroxygen of the hydroxyl group, while in Cu (II) complexes, the binding sites were the oxygen of ethoxyl groups and the primary alcoholic O atom of glucopyranose rings. These complexes would most likely exhibit an octahedral geometry with Cr (III) and Ni (II), but a square planar configuration in the Cu (II) complex [16]. |

CMC-金屬絡(luò)合物 CMC和過度金屬形成高分子絡(luò)合物。 Cr (III) 和 Ni (II)絡(luò)合物中的結(jié)合位點(diǎn)是羥基上的醚氧,而在Cu (II)絡(luò)合物中結(jié)合位點(diǎn)是羥乙基上的氧和吡喃葡萄糖環(huán)上的一級醇化的O原子。這些絡(luò)合物大都傾向于和Cr (III) and Ni (II)形成八面體結(jié)構(gòu),但是在 Cu (II)絡(luò)合物中表現(xiàn)出平面四方型構(gòu)型。 |
