摘要
The reaction of cefalexine anions (Cpx−) with Mn2+, Co2+, Ni2+, Zn2+, and Cd2+ ions in aqueous solution at 20°C and ionic strength 0.1 was studied by pH-metry. In weakly alkaline medium, unstable complexes MCpx+ and M(OH)Cpx are formed, in which Cpx− behaves as a monodentate lidand coordinated through the amino group.
