摘　　要：The liquid membrane oscillation of a novel water（aqueous tetradecyl trimethyl ammoniumbromide,TTAB and alcohol solution）/oil（picric acid in chloroform solution）/water（aqueous glucose solution） system was investigated by means of a homemade device.The results show that the water（aqueous 7 mmol/L TTAB and 0.5 mol/L n-propanol solution）/oil（0.5 mmol/L icric acid in chloroform solution）/water（0.1 mol/L glucose solution） system performed sustained and stable oscillation at 30℃.The oscillation curve under optimized conditions is considered to be referent.Several oscillation curves were accumulated with the addition of different amino acids.The results showed that the novel system can recognize the added amino acids such as L-tryptophan,L-tyrosine,and D,L-tyrosine.And there is corresponding relationship between the change of curve shape and the quantity of amino acid added.The liquid membrane oscillation of a novel water（aqueous tetradecyl trimethyl ammoniumbromide,TTAB and alcohol solution）/oil（picric acid in chloroform solution）/water（aqueous glucose solution） system was investigated by means of a homemade device.The results show that the water（aqueous 7 mmol/L TTAB and 0.5 mol/L n-propanol solution）/oil（0.5 mmol/L icric acid in chloroform solution）/water（0.1 mol/L glucose solution） system performed sustained and stable oscillation at 30℃.The oscillation curve under optimized conditions is considered to be referent.Several oscillation curves were accumulated with the addition of different amino acids.The results showed that the novel system can recognize the added amino acids such as L-tryptophan,L-tyrosine,and D,L-tyrosine.And there is corresponding relationship between the change of curve shape and the quantity of amino acid added.
