Use of zeolites and antibacterial copper ions to synthesize antibacterial zeolites with the methods of liquid and solid ion exchange is discussed in this paper.

HbA 1c; low performance liquid chromatography (LPLC); ion exchange chromatography (IEC).

The extraction of amino acids by ion-exchange, liquid membrane and reverse micelle and their applications in the separation of hair-hydrolyzed amino acids are summarized.
